122-557: Morris Ranch is a ghost town , located 8.5 miles (13.7 km) southwest of Fredericksburg in Gillespie County , in the U.S. state of Texas . The area was begun as a thoroughbred horse ranch by New Yorker Francis Morris in 1856, and the town grew up around it. In 1962, the school district was merged with Fredericksburg Independent School District , and the Morris Ranch School ceased operations. The Morris Ranch Schoolhouse

244-420: A "bust" (e.g., catastrophic resource price collapse). A gold rush often brought intensive but short-lived economic activity to a remote village, only to leave a ghost town once the resource was depleted. Boomtowns can often decrease in size as quickly as they grew. Sometimes, all, or nearly all, of the population can desert the town, resulting in a ghost town. The dismantling of a boomtown can often occur on

366-465: A concern as well, and where enforced, modern practices have significantly improved safety in mines. Unregulated, poorly regulated or illegal mining , especially in developing economies , frequently contributes to local human rights violations and environmental conflicts . Mining can also perpetuate political instability through resource conflicts . Since the beginning of civilization, people have used stone , clay and, later, metals found close to

488-636: A hopper and a shaking screen or trommel which frees the desired minerals from the waste gravel. The minerals are then concentrated using sluices or jigs. Large drills are used to sink shafts, excavate stopes, and obtain samples for analysis. Trams are used to transport miners, minerals and waste. Lifts carry miners into and out of mines, and move rock and ore out, and machinery in and out, of underground mines. Huge trucks, shovels and cranes are employed in surface mining to move large quantities of overburden and ore. Processing plants use large crushers, mills, reactors, roasters and other equipment to consolidate

610-703: A host ore deposit exhausted by mining ). The town may have also declined because of natural or human-caused disasters such as floods , prolonged droughts, extreme heat or extreme cold, government actions, uncontrolled lawlessness, war, pollution, or nuclear and radiation-related accidents and incidents . The term can sometimes refer to cities, towns, and neighborhoods that, though still populated, are significantly less so than in past years; for example, those affected by high levels of unemployment and dereliction. Some ghost towns, especially those that preserve period-specific architecture, have become tourist attractions. Some examples are Bannack, Montana and Oatman, Arizona in

732-875: A mass of actual rock. Both types of ore deposit, placer or lode, are mined by both surface and underground methods. Some mining, including much of the rare earth elements and uranium mining , is done by less-common methods, such as in-situ leaching : this technique involves digging neither at the surface nor underground. The extraction of target minerals by this technique requires that they be soluble, e.g., potash , potassium chloride , sodium chloride , sodium sulfate , which dissolve in water. Some minerals, such as copper minerals and uranium oxide , require acid or carbonate solutions to dissolve. Explosives in Mining Explosives have been used in surface mining and sub-surface mining to blast out rock and ore intended for processing. The most common explosive used in mining

854-426: A mining operation. Once the analysis determines a given ore body is worth recovering, development begins to create access to the ore body. The mine buildings and processing plants are built, and any necessary equipment is obtained. The operation of the mine to recover the ore begins and continues as long as the company operating the mine finds it economical to do so. Once all the ore that the mine can produce profitably

976-503: A more sustainable future, the demand for metals is set to skyrocket. Between 2022 and 2050, an estimated 7 billion metric tons of metals will need to be extracted. Steel will account for the largest portion of this total at 5 billion tons, followed by aluminum at 950 million tons, copper at 650 million tons, graphite at 170 million tons, nickel at 100 million tons, and other metals. Notably, the energy expenditure required to extract these metals will soon surpass that of coal mining, highlighting

1098-499: A one-room schoolhouse. Another example of infrastructure remaining is the former town of Weston, Illinois , that voted itself out of existence and turned the land over for construction of the Fermi National Accelerator Laboratory . Many houses and even a few barns remain, used for housing visiting scientists and storing maintenance equipment, while roads that used to cross through the site have been blocked off at

1220-586: A part in the abandonment of settlements within Europe. Two examples are Pripyat and Chernobyl . After the Chernobyl disaster of 1986, both cities were evacuated due to dangerous radiation levels within the area. As of today, Pripyat remains completely abandoned, and Chernobyl has around 500 remaining inhabitants. Another example is Todoque in the Canary Islands, Spain. During the 2021 Cumbre Vieja volcanic eruption ,

1342-444: A planned basis. Mining companies nowadays will create a temporary company town to service a mine site, building all the accommodations, shops and services required, and then remove them once the resource has been extracted. Modular buildings can be used to facilitate the process. In some cases, multiple factors may remove the economic basis for a community; some former mining towns on U.S. Route 66 suffered both mine closures when

1464-448: A recent economic and holiday population surge. Another town, Sungai Lembing , Malaysia, was almost deserted due to closure of a tin mine in 1986 was revived in 2001 and has become a tourist destination since then. Foncebadón , a village in León , Spain, that was mostly abandoned and only inhabited by a mother and son, is slowly being revived owing to the ever-increasing stream of pilgrims on

1586-434: A result of a natural or human-made disaster or other causes; they restrict the term to settlements that were deserted because they were no longer economically viable. Some believe that any settlement with visible tangible remains should not be called a ghost town; others say, conversely, that a ghost town should contain the tangible remains of buildings. Whether or not the settlement must be completely deserted, or may contain

1708-518: A school, a cotton gin , and a flour mill. Approximately 200 mares and ten stallions were at the ranch, with yearling colts either being sold or boarded at the Morris stables in Winchester Park, Maryland . Adjacent to the ranch was a racetrack and living quarters for the jockeys , where Hall of Fame Thoroughbred racehorse trainer Max Hirsch got his start. Anti-gambling legislation passed by in

1830-422: A shift towards fly-in fly-out arrangements over building a company town , in order to avoid the development of ghost towns once a mining resource has been fully extracted. The Middle East has many ghost towns and ruins that were created when the shifting of politics or the fall of empires caused capital cities to be socially or economically unviable, such as Ctesiphon . The rise of real-estate speculation and

1952-420: A small population, is also a matter for debate. Generally, though, the term is used in a looser sense, encompassing any and all of these definitions. American author Lambert Florin defined a ghost town as "a shadowy semblance of a former self." Factors leading to the abandonment of towns include depleted natural resources, economic activity shifting elsewhere, railroads and roads bypassing or no longer accessing

2074-634: A string of ghost towns in areas such as the Solana Valley . Traditional agricultural practices such as sheep and goat rearing, on which the mountain village economy was based, were not taken over by the local youth, especially after the lifestyle changes that swept over rural Spain during the second half of the 20th century. Examples for ghost towns in Italy include the medieval village of Fabbriche di Careggine near Lago di Vagli , in province of Lucca , in Tuscany ,

2196-408: A strong inducement to extract these metals or to lease the deposits and collect royalties from mine operators. English, German , and Dutch capital combined to finance extraction and refining . Hundreds of German technicians and skilled workers were brought over; in 1642 a colony of 4,000 foreigners was mining and smelting copper at Keswick in the northwestern mountains. Use of water power in

2318-464: A town's life. In 1944, occupying German Waffen-SS troops murdered almost the entire population of the French village Oradour-sur-Glane . A new settlement was built nearby after the war, but the old town was left depopulated on the orders of President Charles de Gaulle , as a permanent memorial. In Germany, numerous smaller towns and villages in the former eastern territories were completely destroyed in

2440-635: Is ammonium nitrate . Between 1870 and 1920, in Queensland Australia, an increase in mining accidents lead to more safety measures surrounding the use of explosives for mining. In the United States of America, between 1990 and 1999, about 22.3 billion kilograms of explosives were used in mining quarrying and other industries; Moreover " coal mining used 66.4%, nonmetal mining and quarrying 13.5%, metal mining 10.4%, construction 7.1%, and all other users 2.6%". Artisanal and small-scale mining (ASM)

2562-811: Is a blanket term for a type of subsistence mining involving a miner who may or may not be officially employed by a mining company but works independently, mining minerals using their own resources, usually by hand. While there is no completely coherent definition for ASM, artisanal mining generally includes miners who are not officially employed by a mining company and use their own resources to mine. As such, they are part of an informal economy . ASM also includes, in small-scale mining, enterprises or individuals that employ workers for mining, but who generally still use similar manually-intensive methods as artisanal miners (such as working with hand tools). In addition, ASM can be characterized as distinct from large-scale mining (LSM) by less efficient extraction of pure minerals from

2684-506: Is dependent on investment, labor, energy, refining, and transportation cost. Mining operations can create a negative environmental impact, both during the mining activity and after the mine has closed. Hence, most of the world's nations have passed regulations to decrease the impact; however, the outsized role of mining in generating business for often rural, remote or economically depressed communities means that governments often fail to fully enforce such regulations. Work safety has long been

2806-476: Is done by removing surface vegetation, dirt, and bedrock to reach buried ore deposits. Techniques of surface mining include: open-pit mining , which is the recovery of materials from an open pit in the ground; quarrying , identical to open-pit mining except that it refers to sand, stone and clay; strip mining , which consists of stripping surface layers off to reveal ore underneath; and mountaintop removal , commonly associated with coal mining, which involves taking

2928-613: Is mining upward, creating a sloping underground room, long wall mining , which is grinding a long ore surface underground, and room and pillar mining, which is removing ore from rooms while leaving pillars in place to support the roof of the room. Room and pillar mining often leads to retreat mining , in which supporting pillars are removed as miners retreat, allowing the room to cave in, thereby loosening more ore. Additional sub-surface mining methods include hard rock mining , bore hole mining, drift and fill mining, long hole slope mining, sub level caving, and block caving . Heavy machinery

3050-484: Is much more common, and produces, for example, 85% of minerals (excluding petroleum and natural gas) in the United States, including 98% of metallic ores. Targets are divided into two general categories of materials: placer deposits , consisting of valuable minerals contained within river gravels, beach sands, and other unconsolidated materials ; and lode deposits , where valuable minerals are found in veins, in layers, or in mineral grains generally distributed throughout

3172-413: Is not of immediate interest to the miner. The total movement of ore and waste constitutes the mining process. Often more waste than ore is mined during the life of a mine, depending on the nature and location of the ore body. Waste removal and placement is a major cost to the mining operator, so a detailed characterization of the waste material forms an essential part of the geological exploration program for

3294-471: Is now home to more than four million people. Wars and rebellions in some African countries have left many towns and villages deserted. Since 2003, when President François Bozizé came to power, thousands of citizens of the Central African Republic have been forced to flee their homes as a result of the escalating conflict between armed rebels and government troops. Villages accused of supporting

3416-584: Is recovered, reclamation can begin, to make the land used by the mine suitable for future use. Technical and economic challenges notwithstanding, successful mine development must also address human factors. Working conditions are paramount to success, especially with regard to exposures to dusts, radiation, noise, explosives hazards, and vibration, as well as illumination standards. Mining today increasingly must address environmental and community impacts, including psychological and sociological dimensions. Thus, mining educator Frank T. M. White (1909–1971), broadened

3538-634: Is the largest producer of diamonds in Africa, with an estimated 12 million carats in 2019. Other types of mining reserves in Africa include cobalt , bauxite , iron ore , coal, and copper . Gold and coal mining started in Australia and New Zealand in the 19th century. Nickel has become important in the economy of New Caledonia . In Fiji , in 1934, the Emperor Gold Mining Company Ltd. established operations at Vatukoula , followed in 1935 by

3660-423: Is to conduct a feasibility study to evaluate the financial viability, the technical and financial risks, and the robustness of the project. This is when the mining company makes the decision whether to develop the mine or to walk away from the project. This includes mine planning to evaluate the economically recoverable portion of the deposit, the metallurgy and ore recoverability, marketability and payability of

3782-419: Is used in mining to explore and develop sites, to remove and stockpile overburden, to break and remove rocks of various hardness and toughness, to process the ore, and to carry out reclamation projects after the mine is closed. Bulldozers, drills, explosives and trucks are all necessary for excavating the land. In the case of placer mining , unconsolidated gravel, or alluvium , is fed into machinery consisting of

3904-460: The Sperrgebiet ("forbidden zone"), effectively criminalizing new settlement. The small mining towns of this area, among them Pomona , Elizabeth Bay and Kolmanskop , were exempt from this ban, but the denial of new land claims soon rendered all of them ghost towns. The town of Dhanushkodi , India is a ghost town. It was destroyed during the 1964 Rameswaram cyclone and remains uninhabited in

4026-464: The Chernobyl disaster of 1986, dangerously high levels of nuclear contamination escaped into the surrounding area, and nearly 200 towns and villages in Ukraine and neighbouring Belarus were evacuated, including the cities of Pripyat and Chernobyl . The area was so contaminated that many of the evacuees were never permitted to return to their homes. Pripyat is the most famous of these abandoned towns; it

4148-464: The Greek author Diodorus Siculus , who mentions fire-setting as one method used to break down the hard rock holding the gold . One of the complexes is shown in one of the earliest known mining maps. The miners crushed the ore and ground it to a fine powder before washing the powder for the gold dust known as the dry and wet attachment processes. Mining in Europe has a very long history. Examples include

4270-684: The Interstate highway system replaced the railroads as the favored means of transportation. Ghost towns are common in mining or mill towns in all the western states, and many eastern and southern states as well. Residents are compelled to leave in search of more productive areas when the resources that had created an employment boom in these towns were eventually exhausted. Sometimes a ghost town consists of many abandoned buildings as in Bodie, California , or standing ruins as in Rhyolite, Nevada , while elsewhere only

4392-554: The Köppen climate classification system, Morris Ranch has a humid subtropical climate , abbreviated "Cfa" on climate maps. Ghost town A ghost town , deserted city , extinct town , or abandoned city is an abandoned settlement, usually one that contains substantial visible remaining buildings and infrastructure such as roads. A town often becomes a ghost town because the economic activity that supported it (usually industrial or agricultural) has failed or ended for any reason (e.g.

4514-581: The National Register of Historic Places . Starting in 2002, an attempt to declare an official ghost town in California stalled when the adherents of the town of Bodie and those of Calico , in Southern California , could not agree on the most deserving settlement for the recognition. A compromise was eventually reached—Bodie became the official state gold rush ghost town, while Calico was named

4636-576: The Stanford Battle Area , were commandeered by the War Office for use as training grounds for British and US troops. Although this was intended to be a temporary measure, the residents were never allowed to return, and the villages have been used for military training ever since. Three miles or 5 km southeast of Imber is Copehill Down , a deserted village purpose-built for training in urban warfare . Disasters & natural disasters have played

Spain was one of the most important mining regions, but all regions of the Roman Empire were exploited. In Great Britain the natives had mined minerals for millennia , but after the Roman conquest , the scale of the operations increased dramatically, as

The oldest-known mine on archaeological record is the Ngwenya Mine in Eswatini (Swaziland) , which radiocarbon dating shows to be about 43,000 years old. At this site Paleolithic humans mined hematite to make the red pigment ochre . Mines of a similar age in Hungary are believed to be sites where Neanderthals may have mined flint for weapons and tools. Ancient Egyptians mined malachite at Maadi . At first, Egyptians used

The ranch was inherited by John's sons Alfred and David and eventually by Alfred's son Captain John A. Morris. Clayton Morris succeeded Charles Morris as manager, and in 1902 sold the horses and subdivided

5124-505: The 21st century begins, a globalized mining industry of large multinational corporations has arisen. Peak minerals and environmental impacts have also become a concern. Different elements, particularly rare-earth minerals , have begun to increase in demand as a result of new technologies. In 2023, 8.5 billion metric tons of coal were extracted from the Earth's crust. However, as the global economy transitions away from fossil fuels and toward

5246-663: The 7th century to the 14th century. Gold was often traded to Mediterranean economies that demanded gold and could supply salt , even though much of Africa was abundant with salt due to the mines and resources in the Sahara desert . The trading of gold for salt was mostly used to promote trade between the different economies. Since the Great Trek in the 19th century, after, gold and diamond mining in Southern Africa has had major political and economic impacts. The Democratic Republic of Congo

5368-524: The Earth's surface. These were used to make early tools and weapons; for example, high quality flint found in northern France , southern England and Poland was used to create flint tools . Flint mines have been found in chalk areas where seams of the stone were followed underground by shafts and galleries. The mines at Grimes Graves and Krzemionki are especially famous, and like most other flint mines, are Neolithic in origin (c. 4000–3000 BC). Other hard rocks mined or collected for axes included

5490-595: The French crown to operate mines in 1733, becoming "the first practical miner on Lake Superior"; seven years later, mining was halted by an outbreak between Sioux and Chippewa tribes. Mining in the United States became widespread in the 19th century, and the United States Congress passed the General Mining Act of 1872 to encourage mining of federal lands. As with the California Gold Rush in

5612-630: The Loloma Gold Mines, N.L., and then by Fiji Mines Development Ltd. (aka Dolphin Mines Ltd.). These developments ushered in a “mining boom”, with gold production rising more than a hundred-fold, from 931.4 oz in 1934 to 107,788.5 oz in 1939, an order of magnitude then comparable to the combined output of New Zealand and Australia's eastern states. During prehistoric times, early Americans mined large amounts of copper along Lake Superior 's Keweenaw Peninsula and in nearby Isle Royale ; metallic copper

5734-477: The Romans needed Britannia 's resources, especially gold , silver , tin , and lead . Roman techniques were not limited to surface mining. They followed the ore veins underground once opencast mining was no longer feasible. At Dolaucothi they stoped out the veins and drove adits through bare rock to drain the stopes. The same adits were also used to ventilate the workings, especially important when fire-setting

5856-589: The Spanish to pulverize ore after being mined. This device was powered by animals and used the same principles used for grain threshing . Much of the knowledge of medieval mining techniques comes from books such as Biringuccio 's De la pirotechnia and probably most importantly from Georg Agricola 's De re metallica (1556). These books detail many different mining methods used in German and Saxon mines. A prime issue in medieval mines, which Agricola explains in detail,

Stennis Space Center (SSC), a rocket testing facility in Hancock County, Mississippi (on the Mississippi side of the Pearl River , which is the Mississippi – Louisiana state line). This required NASA to acquire a large (approximately 34-square-mile or 88-square-kilometre) buffer zone because of the loud noise and potential dangers associated with testing such rockets. Five thinly populated rural Mississippi communities (Gainesville, Logtown, Napoleon, Santa Rosa, and Westonia), plus

6100-730: The Umm el-Sawwan site; gypsum was used to make funerary items for private tombs. Other minerals mined in Egypt from the Old Kingdom (2649-2134 BC) until the Roman Period (30 BC-AD 395) including granite , sandstone , limestone , basalt , travertine , gneiss , galena , and amethyst . Mining in Egypt occurred in the earliest dynasties. The gold mines of Nubia were among the largest and most extensive of any in Ancient Egypt. These mines are described by

6222-545: The United States, and Canada, where housing is often used as an investment rather than for habitation. Railroads and roads bypassing or no longer reaching a town can also create a ghost town. This was the case in many of the ghost towns along Ontario's historic Opeongo Line , and along U.S. Route 66 after motorists bypassed the latter on the faster moving highways I-44 and I-40 . Some ghost towns were founded along railways where steam trains would stop at periodic intervals for repairs or to take on water. Amboy, California ,

T. Lindsey Baker, author of Ghost Towns of Texas , defines a ghost town as "a town for which the reason for being no longer exists." Some writers discount settlements that were abandoned as

6466-420: The acreage for horse breeding. Charles was ranch manager until 1910. Francis Morris died in 1886. The land was inherited by his son John A. Morris , who spent $ 500,000 on capital improvements and converted the property into a community dedicated to the business of raising thoroughbred horses. The improvements included a hotel for entertaining influential and important individuals, a general store and post office,

6588-406: The aftermath. Many abandoned towns and settlements in the former Soviet Union were established near Gulag labour camps to supply necessary services. Since most of these camps were abandoned in the 1950s, the towns were abandoned as well. One such town is located near the former Gulag camp called Butugychag (also called Lower Butugychag). Other towns were deserted due to deindustrialisation and

6710-521: The bright green malachite stones for ornamentations and pottery . Later, between 2613 and 2494 BC, large building projects required expeditions abroad to the area of Wadi Maghareh in order to secure minerals and other resources not available in Egypt itself. Quarries for turquoise and copper were also found at Wadi Hammamat , Tura , Aswan and various other Nubian sites on the Sinai Peninsula and at Timna . Quarries for gypsum were found at

6832-508: The country, were wiped out due to the Great Famine in the latter half of the 19th century, and the years of economic decline that followed. Catastrophic environmental damage caused by long-term contamination can also create a ghost town. Some notable examples are Times Beach, Missouri , whose residents were exposed to a high level of dioxins , and Wittenoom, Western Australia , which was once Australia's largest source of blue asbestos , but

6954-417: The cutter-head is progressively launched further into the coal seam. High wall mining can produce thousands of tons of coal in contour-strip operations with narrow benches, previously mined areas, trench mine applications and steep-dip seams. Sub-surface mining consists of digging tunnels or shafts into the earth to reach buried ore deposits. Ore, for processing, and waste rock, for disposal, are brought to

During World War II it was an important partisan base and it was definitively abandoned in the 1980s, when the last family who lived here, left the village. . Two projects have been proposed for

7198-725: The development of ghost towns. Tyneham , in Dorset , was requisitioned for military exercises during the Second World War , and remains unpopulated, being littered with unexploded munitions from regular shelling. A few ghost towns have managed to get a second life, and this happens through a variety of reasons. One of these reasons is heritage tourism generating a new economy able to support residents. For example, Walhalla, Victoria , Australia, became almost deserted after its gold mine ceased operation in 1914, but owing to its accessibility and proximity to other attractive locations, it has had

7320-624: The economic crises of the early 1990s attributed to post-Soviet conflicts – one example being Tkvarcheli in Georgia, a coal mining town that suffered a drastic population decline as a result of the War in Abkhazia in the early 1990s. Although in 2010s Chinese ghost cities became a frequent feature of discourse regarding China's economy and urbanization , under-occupied cities filled up. Writing in 2023, academic and former UK diplomat Kerry Brown described

7442-410: The edges of the property, with gatehouses or barricades to prevent unsupervised access. Construction of dams has produced ghost towns that have been left underwater. Examples include: Some towns become deserted when their populations were massacred , deported, or expelled. Examples include Kayaköy, an ancient Greek city abandoned in 1923 as result of population exchange between Greece and Turkey and

7564-431: The entire population to flee. Upon seizing the city, Armenian forces destroyed much of the town to discourage Azerbaijanis from returning. More damage occurred in the following decades when locals looted the abandoned town for building materials. It is currently almost entirely ruined and uninhabited. Natural and human-made disasters can create ghost towns. For example, after being flooded more than 30 times since their town

7686-698: The focus to the “total environment of mining”, including reference to community development around mining, and how mining is portrayed to an urban society, which depends on the industry, although seemingly unaware of this dependency. He stated, “[I]n the past, mining engineers have not been called upon to study the psychological, sociological and personal problems of their own industry – aspects that nowadays are assuming tremendous importance. The mining engineer must rapidly expand his knowledge and his influence into these newer fields.” Mining techniques can be divided into two common excavation types: surface mining and sub-surface (underground) mining . Today, surface mining

7808-481: The form of water mills was extensive. The water mills were employed in crushing ore, raising ore from shafts, and ventilating galleries by powering giant bellows . Black powder was first used in mining in Selmecbánya , Kingdom of Hungary (now Banská Štiavnica , Slovakia) in 1627. Black powder allowed blasting of rock and earth to loosen and reveal ore veins. Blasting was much faster than fire-setting and allowed

7930-500: The foundations of former buildings remain as in Graysonia, Arkansas . Old mining camps that have lost most of their population at some stage of their history such as Aspen , Deadwood , Oatman , Tombstone and Virginia City are sometimes referred to as ghost towns although they are presently active towns and cities. Many U.S. ghost towns, such as South Pass City in Wyoming are listed on

8052-400: The growing importance of sustainable metal extraction practices. The process of mining from discovery of an ore body through extraction of minerals and finally to returning the land to its natural state consists of several distinct steps. The first is discovery of the ore body, which is carried out through prospecting or exploration to find and then define the extent, location and value of

8174-578: The idea of Chinese ghost cities as a popular bandwagon which was shown to be a myth. The town of Namie , along with several other towns in Fukushima Prefecture , Japan, was temporarily evacuated as a result of the Fukushima Daiichi nuclear disaster following the 2011 Tohoku earthquake and tsunami . Following ongoing decontamination works, several portions of Namie have been fully reopened to residents, allowing reconstruction and renovation of

8296-519: The last two years of the war. These territories later became part of Poland and the Soviet Union , and many of the smaller settlements were never rebuilt or repopulated, for example Kłomino ( Westfalenhof ), Pstrąże ( Pstransse ), and Janowa Góra ( Johannesberg ). Some villages in England were also abandoned during the war, but for different reasons. Imber , on Salisbury Plain , and several villages in

Hundreds of buildings were destroyed, including the parish Church of Saint Pius X, the health center, the headquarters of the neighborhood association, the School of Early Childhood Education, and Los Campitos Elementary School and the Todoque Elementary and the Infant Education School, and by October 10, new lava flows destroyed the remaining buildings that were still standing, leaving

8540-525: The metals due to the difficulties of transporting them, but the copper was eventually traded throughout the continent along major river routes. In the early colonial history of the Americas, "native gold and silver was quickly expropriated and sent back to Spain in fleets of gold- and silver-laden galleons", the gold and silver originating mostly from mines in Central and South America. Turquoise dated at 700 AD

8662-753: The mid-19th century, mining for minerals and precious metals, along with ranching , became a driving factor in the U.S. Westward Expansion to the Pacific coast. With the exploration of the West, mining camps sprang up and "expressed a distinctive spirit, an enduring legacy to the new nation"; Gold Rushers would experience the same problems as the Land Rushers of the transient West that preceded them. Aided by railroads, many people traveled West for work opportunities in mining. Western cities such as Denver and Sacramento originated as mining towns. When new areas were explored, it

8784-442: The mid-sixteenth century. On the continent, mineral deposits belonged to the crown, and this regalian right was stoutly maintained. But in England, royal mining rights were restricted to gold and silver (of which England had virtually no deposits) by a judicial decision of 1568 and a law in 1688. England had iron , zinc , copper , lead , and tin ores. Landlords who owned the base metals and coal under their estates then had

8906-432: The minehead, where the water was stored in large reservoirs and tanks. When a full tank was opened, the flood of water sluiced away the overburden to expose the bedrock underneath and any gold-bearing veins. The rock was then worked by fire-setting to heat the rock, which would be quenched with a stream of water. The resulting thermal shock cracked the rock, enabling it to be removed by further streams of water from

9028-431: The mining of previously impenetrable metals and ores. In 1762, one of the world's first mining academies was established in the same town there. The widespread adoption of agricultural innovations such as the iron plowshare , as well as the growing use of metal as a building material, was also a driving force in the tremendous growth of the iron industry during this period. Inventions like the arrastra were often used by

9150-471: The most notable are Anyox , Kitsault , and Ocean Falls . Some ghost towns have revived their economies and populations due to historical and eco-tourism, such as Barkerville ; once the largest town north of Kamloops , it is now a year-round provincial museum. In Quebec, Val-Jalbert is a well-known tourist ghost town; founded in 1901 around a mechanical pulp mill that became obsolete when paper mills began to break down wood fibre by chemical means, it

9272-514: The nation's second-largest city with 1 million people, was a village of only a few thousand people before colonization. Alexandria , the second-largest city of Egypt, was a flourishing city in the Ancient era, but declined during the Middle Ages. It underwent a dramatic revival during the 19th century; from a population of 5,000 in 1806, it grew into a city of more than 200,000 inhabitants by 1882, and

9394-464: The northern portion of a sixth ( Pearlington ), along with 700 families in residence, had to be completely relocated away from the facility. Sometimes the town might cease to officially exist, but the physical infrastructure remains. For example, the five Mississippi communities that had to be abandoned to build SSC still have remnants of those communities within the facility itself. These include city streets, now overgrown with forest flora and fauna, and

9516-458: The official state silver rush ghost town. Mining Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation or restoration of the land after the mine is closed. Mining materials are often obtained from ore bodies, lodes , veins , seams , reefs , or placer deposits . The exploitation of these deposits for raw materials

9638-405: The ore body. This leads to a mathematical resource estimation to estimate the size and grade of the deposit. This estimation is used to conduct a pre-feasibility study to determine the theoretical economics of the ore deposit. This identifies, early on, whether further investment in estimation and engineering studies is warranted and identifies key risks and areas for further work. The next step

9760-462: The ore concentrates, engineering concerns, milling and infrastructure costs, finance and equity requirements, and an analysis of the proposed mine from the initial excavation all the way through to reclamation. The proportion of a deposit that is economically recoverable is dependent on the enrichment factor of the ore in the area. To gain access to the mineral deposit within an area it is often necessary to mine through or remove waste material which

9882-442: The ore, lower wages, decreased occupational safety, benefits, and health standards for miners, and a lack of environmental protection measures. Artisanal miners often undertake the activity of mining seasonally. For example, crops are planted in the rainy season , and mining is pursued in the dry season . However, they also frequently travel to mining areas and work year-round. There are four broad types of ASM: Surface mining

10004-621: The original French village at Oradour-sur-Glane which was destroyed on 10 June 1944 when 642 of its 663 inhabitants were killed by a German Waffen-SS company. A new village was built after the war on a nearby site, and the ruins of the original have been maintained as a memorial. Another example is Aghdam , a city in Azerbaijan . Armenian forces occupied Aghdam in July 1993 during the First Nagorno-Karabakh War . The heavy fighting forced

10126-556: The overhead tanks. The Roman miners used similar methods to work cassiterite deposits in Cornwall and lead ore in the Pennines . Sluicing methods were developed by the Romans in Spain in 25 AD to exploit large alluvial gold deposits, the largest site being at Las Medulas , where seven long aqueducts tapped local rivers and sluiced the deposits. The Romans also exploited the silver present in

10248-464: The ranch into tenant cotton farms. Clayton's son Reginald inherited the ranch from his father, but it was no longer a vital business. Although some of the original buildings were still standing in the year 2000, the population began a decline after the subdivision happened. By 1968, no population was listed. When the Morris Ranch post office opened in 1893, Guy D. Anderson was the first postmaster. He

10370-522: The reason for abandonment can arise from a town's intended economic function shifting to another, nearby place. This happened to Collingwood, Queensland , in Outback Australia when nearby Winton outperformed Collingwood as a regional centre for the livestock-raising industry. The railway reached Winton in 1899, linking it with the rest of Queensland , and Collingwood was a ghost town by the following year. More broadly across Australia, there has been

10492-564: The reason for their complete abandonment. Examples are Marinka and Soledar in Donbas in Ukraine . Canada has several ghost towns in parts of British Columbia , Alberta , Ontario , Saskatchewan , Newfoundland and Labrador , and Quebec . Some were logging towns or dual mining and logging sites, often developed at the behest of the company . In Alberta and Saskatchewan, most ghost towns were once farming communities that have since died off due to

10614-503: The rebels, such as Beogombo Deux near Paoua , are ransacked by government soldiers. Those who are not killed have no choice but to escape to refugee camps. The instability in the region also leaves organized and well-equipped bandits free to terrorize the populace, often leaving villages abandoned in their wake. Elsewhere in Africa, the town of Lukangol was burnt to the ground during tribal clashes in South Sudan . Before its destruction,

10736-756: The recovery of the village: in 2011 the proposal of Movimento Libero Perseo "Roveraia eco - lab", based on sustainability, and in 2019 there was a proposal aiming to recover the village with a mix of functions called "Ecomuseum of Pratomagno". In the United Kingdom, thousands of villages were abandoned during the Middle Ages, as a result of Black Death , revolts, and enclosure , the process by which vast amounts of farmland became privately owned. Since there are rarely any visible remains of these settlements, they are not generally considered ghost towns; instead, they are referred to in archaeological circles as deserted medieval villages . Sometimes, wars and genocide end

10858-431: The remaining part of a coal seam previously exploited by other surface-mining techniques has too much overburden to be removed but can still be profitably exploited from the side of the artificial cliff made by previous mining. A typical cycle alternates sumping, which undercuts the seam, and shearing, which raises and lowers the cutter-head boom to cut the entire height of the coal seam. As the coal recovery cycle continues,

10980-536: The removal of the railway through the town or the bypass of a highway. The ghost towns in British Columbia were predominantly mining towns and prospecting camps as well as canneries and, in one or two cases, large smelter and pulp mill towns. British Columbia has more ghost towns than any other jurisdiction on the North American continent, with more than 1,500 abandoned or semi-abandoned towns and localities. Among

11102-502: The resources were depleted and loss of highway traffic as US 66 was diverted from places like Oatman, Arizona , onto a more direct path. Mine and pulp mill closures have led to many ghost towns in British Columbia, Canada, including several relatively recent ones: Ocean Falls , which closed in 1973 after the pulp mill was decommissioned; Kitsault , whose molybdenum mine shut down after only 18 months in 1982; and Cassiar , whose asbestos mine operated from 1952 to 1992. In other cases,

11224-458: The resulting possibility of real-estate bubbles (sometimes due to outright overbuilding by land developers) may also trigger the appearance of certain elements of a ghost town, as real-estate prices initially rise (whereupon affordable housing becomes less available) and then later fall for a variety of reasons that are often tied to economic cycles and/or marketing hubris. This has been observed to occur in various countries, including Spain, China,

11346-639: The road to Santiago de Compostela . Some ghost towns (e.g. Riace , Muñotello ) are being repopulated by respectively refugees and homeless people . In Riace, this was accomplished by a scheme funded by the Italian government which offers the housing to refugees and in Muñotello it was accomplished through an NGO ( Madrina Foundation ). In Algeria, many cities became hamlets after the end of Late Antiquity . They were revived with shifts in population during and after French colonization of Algeria . Oran , currently

11468-446: The shafts could no longer be pumped dry with the available technology. Although an increased use of banknotes , credit and copper coins during this period did decrease the value of, and dependence on, precious metals , gold and silver still remained vital to the story of medieval mining. Due to differences in the social structure of society, the increasing extraction of mineral deposits spread from central Europe to England in

11590-558: The silver mines of Laurium , which helped support the Greek city state of Athens . Although they had over 20,000 slaves working them, their technology was essentially identical to their Bronze Age predecessors. At other mines, such as on the island of Thassos , marble was quarried by the Parians after they arrived in the 7th century BC. The marble was shipped away and was later found by archaeologists to have been used in buildings including

11712-474: The surface through the tunnels and shafts. Sub-surface mining can be classified by the type of access shafts used, and the extraction method or the technique used to reach the mineral deposit. Drift mining uses horizontal access tunnels, slope mining uses diagonally sloping access shafts, and shaft mining uses vertical access shafts. Mining in hard and soft rock formations requires different techniques. Other methods include shrinkage stope mining , which

11834-590: The tomb of Amphipolis. Philip II of Macedon , the father of Alexander the Great , captured the gold mines of Mount Pangeo in 357 BC to fund his military campaigns. He also captured gold mines in Thrace for minting coinage, eventually producing 26 tons per year. However, it was the Romans who developed large-scale mining methods, especially the use of large volumes of water brought to the minehead by numerous aqueducts . The water

11956-448: The top of a mountain off to reach ore deposits at depth. Most placer deposits, because they are shallowly buried, are mined by surface methods. Finally, landfill mining involves sites where landfills are excavated and processed. Landfill mining has been thought of as a long-term solution to methane emissions and local pollution. High wall mining, which evolved from auger mining, is another form of surface mining. In high wall mining,

12078-614: The top slats. Many examples of such devices have been found in old Roman mines and some examples are now preserved in the British Museum and the National Museum of Wales . Mining as an industry underwent dramatic changes in medieval Europe . The mining industry in the early Middle Ages was mainly focused on the extraction of copper and iron . Other precious metals were also used, mainly for gilding or coinage. Initially, many metals were obtained through open-pit mining , and ore

12200-563: The town had a population of 20,000. The Libyan town of Tawergha had a population of around 25,000 before it was abandoned during the 2011 civil war , and it has remained empty since. Many of the ghost towns in mineral-rich Africa are former mining towns. Shortly after the start of the 1908 diamond rush in German South-West Africa , now known as Namibia , the German Imperial government claimed sole mining rights by creating

12322-535: The town practically erased from the map. An example in the UK of a ghost village which was abandoned before it was ever occupied is at Polphail , Argyll and Bute . The planned development of an oil rig construction facility nearby never materialised, and a village built to house the workers and their families became deserted the moment the building contractors finished their work. War activities, displacements and complete destruction of cities as result of intense fighting were

12444-553: The town's buildings to be undertaken and resettlement of the area to take place. Urbanization – the migration of a country's rural population into the cities – has left many European towns and villages deserted. An increasing number of settlements in Bulgaria are becoming ghost towns for this reason; at the time of the 2011 census, the country had 181 uninhabited settlements. In Hungary, dozens of villages are also threatened with abandonment. The first village officially declared as "dead"

12566-406: The town, human intervention, disasters, massacres, wars, the shifting of politics or fall of empires, and volcanic eruptions. A town can also be abandoned when it is part of an exclusion zone due to natural or human-made causes . Ghost towns may result when the single activity or resource that created a boomtown (e.g., nearby mine, mill or resort) is depleted or the resource economy undergoes

12688-461: The world's gold, followed by the establishment of large mines such as the Mount Morgan Mine , which ran for nearly a hundred years, Broken Hill ore deposit (one of the largest zinc-lead ore deposits), and the iron ore mines at Iron Knob . After declines in production, another boom in mining occurred in the 1960s. In the early 21st century, Australia remains a major world mineral producer. As

12810-468: The world, which was increasingly demanding copper for electrical and household goods. Canada's mining industry grew more slowly than did the United States due to limitations in transportation, capital, and U.S. competition; Ontario was the major producer of the early 20th century with nickel, copper, and gold. Meanwhile, Australia experienced the Australian gold rushes and by the 1850s was producing 40% of

12932-455: Was Gyűrűfű  [ hu ] in the late 1970s, but later it was repopulated as an eco-village . Some other depopulated villages were successfully saved as small rural resorts, such as Kán , Tornakápolna , Szanticska , Gorica , and Révfalu . In Spain, large zones of the mountainous Iberian System and the Pyrenees have undergone heavy depopulation since the early 20th century, leaving

13054-482: Was abandoned due to an uncontainable mine fire , which began in 1962 and still rages to this day; eventually the fire reached an abandoned mine underneath the nearby town of Byrnesville , which caused that mine to catch on fire too and forced the evacuation of that town as well. Ghost towns may also occasionally come into being due to an anticipated natural disaster – for example, the Canadian town of Lemieux, Ontario ,

13176-582: Was abandoned in 1991 after soil testing revealed that the community was built on an unstable bed of Leda clay . Two years after the last building in Lemieux was demolished, a landslide swept part of the former town-site into the South Nation River . Two decades earlier, the Canadian town of Saint-Jean-Vianney , Québec, also constructed on a Leda clay base, had been abandoned after a landslide on 4 May 1971, which swept away 41 homes, killing 31 people. Following

13298-518: Was abandoned when the mill closed in 1927 and re-opened as a park in 1960. Many ghost towns or abandoned communities exist in the American Great Plains , the rural areas of which have lost a third of their population since 1920. Thousands of communities in the northern plains states of Montana , Nebraska , North Dakota , and South Dakota became railroad ghost towns when a rail line failed to materialize. Hundreds of towns were abandoned as

13420-573: Was built for the workers of the Chernobyl Nuclear Power Plant and had a population of almost 50,000 at the time of the disaster. Significant fatality rates from epidemics have produced ghost towns. Some places in eastern Arkansas were abandoned after more than 7,000 Arkansans died during the Spanish flu epidemic of 1918 and 1919. Several communities in Ireland, particularly in the west of

13542-577: Was designated a Recorded Texas Historic Landmark in 1980, and added to the National Register of Historic Places listings in Texas , on March 29, 1983. In 1856, New York City broker Francis Morris bought 23,000 acres (93.08  km ; 35.94  sq mi ) of land in Gillespie and Kerr counties for twenty-five cents an acre. He eventually sold off all but 16,000 acres (64.75  km ; 25.00  sq mi ), and hired his nephew Charles Morris to manage

13664-579: Was founded in 1845, residents of Pattonsburg, Missouri , decided to relocate after two floods in 1993. With government help, the whole town was rebuilt 3 miles or 5 km away. Craco , a medieval village in the Italian region of Basilicata , was evacuated after a landslide in 1963. Nowadays it is a filming location for many movies, including The Passion of The Christ by Mel Gibson , Christ Stopped at Eboli by Francesco Rosi , The Nativity Story by Catherine Hardwicke and Quantum of Solace by Marc Forster . In 1984, Centralia, Pennsylvania ,

13786-612: Was mined in pre-Columbian America; in the Cerillos Mining District in New Mexico , an estimate of "about 15,000 tons of rock had been removed from Mt. Chalchihuitl using stone tools before 1700." In 1727 Louis Denys (Denis) (1675–1741), sieur de La Ronde – brother of Simon-Pierre Denys de Bonaventure and the son-in-law of René Chartier – took command of Fort La Pointe at Chequamegon Bay ; where natives informed him of an island of copper. La Ronde obtained permission from

13908-667: Was part of one such series of villages along the Atlantic and Pacific Railroad across the Mojave Desert . River re-routing is another factor, one example being the towns along the Aral Sea . Ghost towns may be created when land is expropriated by a government, and residents are required to relocate. One example is the village of Tyneham in Dorset, England, acquired during World War II to build an artillery range. A similar situation occurred in

14030-576: Was primarily extracted from shallow depths, rather than through deep mine shafts. Around the 14th century , the growing use of weapons , armour , stirrups , and horseshoes greatly increased the demand for iron. Medieval knights , for example, were often laden with up to 100 pounds (45 kg) of plate or chain link armour in addition to swords , lances and other weapons. The overwhelming dependency on iron for military purposes spurred iron production and extraction processes. The silver crisis of 1465 occurred when all mines had reached depths at which

14152-557: Was shut down in 1966 due to health concerns. Treece and Picher , twin communities straddling the Kansas – Oklahoma border, were once one of the United States' largest sources of zinc and lead , but over a century of unregulated disposal of mine tailings led to groundwater contamination and lead poisoning in the town's children, eventually resulting in a mandatory Environmental Protection Agency buyout and evacuation. Contamination due to ammunition caused by military use may also lead to

14274-406: Was still present near the surface in colonial times. Indigenous peoples used Lake Superior copper from at least 5,000 years ago; copper tools, arrowheads, and other artifacts that were part of an extensive native trade-network have been discovered. In addition, obsidian , flint , and other minerals were mined, worked, and traded. Early French explorers who encountered the sites made no use of

14396-462: Was succeeded by Charles Morris in 1894, who was subsequently succeeded by Clayton Morris in 1910. Clayton Morris served as postmaster until the post office closed in 1954 when the Morris Ranch store was shut down. The town has been the subject of a ghost story involving the death of Morris Ranch resident Mary Elizabeth Simmons Byrd in 1948. The climate in this area is characterized by hot, humid summers and generally mild to cool winters. According to

14518-411: Was the removal of water from mining shafts. As miners dug deeper to access new veins, flooding became a very real obstacle. The mining industry became dramatically more efficient and prosperous with the invention of mechanically- and animal-driven pumps. Iron metallurgy in Africa dates back over four thousand years. Gold became an important commodity for Africa during the trans-Saharan gold trade from

14640-403: Was used for a variety of purposes, including removing overburden and rock debris, called hydraulic mining , as well as washing comminuted , or crushed, ores and driving simple machinery. The Romans used hydraulic mining methods on a large scale to prospect for the veins of ore, especially using a now-obsolete form of mining known as hushing . They built numerous aqueducts to supply water to

14762-461: Was used. At other parts of the site, they penetrated the water table and dewatered the mines using several kinds of machines, especially reverse overshot water-wheels . These were used extensively in the copper mines at Rio Tinto in Spain, where one sequence comprised 16 such wheels arranged in pairs, and lifting water about 24 metres (79 ft). They were worked as treadmills with miners standing on

14884-539: Was usually the gold ( placer and then lode ) and then silver that were taken into possession and extracted first. Other metals would often wait for railroads or canals, as coarse gold dust and nuggets do not require smelting and are easy to identify and transport. In the early 20th century, the gold and silver rush to the western United States also stimulated mining for coal as well as base metals such as copper, lead, and iron. Areas in modern Montana, Utah, Arizona, and later Alaska became predominant suppliers of copper to
