170-583: A national monument in and around Death Valley on February 11, 1933, setting aside almost two million acres (8,100 km ) of southeastern California and small parts of Nevada. The Civilian Conservation Corps (CCC) developed infrastructure in Death Valley National Monument during the Great Depression and on into the early 1940s. The CCC built barracks, graded 500 miles (800 km) of roads, installed water and telephone lines, and

255-399: A dry camp, which was used by a return team and the cycle repeated. The teams hauled more than 20 million pounds (9,100 t) of borax out of Death Valley in the six years of operation, with Pacific Coast Borax shipping their borax by train starting in 1898. Horses were the wheelers , the two closest to the wagon. They were ridden by one of the two men generally required to operate

340-511: A shakedown outing in a 1998 Boron, California , parade. The company spent $ 100,000, refitting the 115-year-old wagons and obtaining harnesses and mules for the performance. There were no plans for additional public appearances for advertising purposes, as the company no longer had a retail product line. U.S. Borax put out a paperback publication titled The Last Ride, the Borax Twenty Mule Team 1883–1999 that included many details about

425-513: A short series of prospecting mines failed to yield evidence of significant ore (these mines now dot the entire area and are a significant hazard to anyone who enters them). The boom towns which sprang up around these mines flourished during the first decade of the 1900s, but soon declined after the Panic of 1907 . The first documented tourist facilities in Death Valley were a set of tent houses built in

510-468: A survivor from much wetter times. UNESCO included Death Valley as the principal feature of its Mojave and Colorado Deserts Biosphere Reserve in 1984. A series of Native American groups inhabited the area from as early as 7000 BC, most recently the Timbisha around 1000 AD who migrated between winter camps in the valleys and summer grounds in the mountains. A group of European-Americans, lost in

595-594: A third wagon for food and water, drawn by a 24-mule team over a 160-mile (260 km) stretch of desert between Columbus, Nevada and Wadsworth, Nevada . The twenty-mule-team wagons were designed to carry 10 short tons (9.1 tonnes) of borax ore at a time. The rear wheels were seven feet (2.1 m) high, and fitted with 1-inch-thick (25 mm) iron tires . The solid oak wagon beds measured 16 feet (4.9 m) long by 6 feet (1.8 m) deep, and weighed 7,800 pounds (3,500 kg) empty. Due to their rugged construction, none ever broke down in transit. The first wagon

680-537: A total of 76 buildings. Trails in the Panamint Range were built to points of scenic interest, and an adobe village, laundry and trading post were constructed for the Timbisha Shoshone Tribe . Five campgrounds, restrooms, an airplane landing field and picnic facilities were also built. The creation of the monument resulted in a temporary closing of the lands to prospecting and mining. However, Death Valley

765-523: Is 9b with an average annual extreme minimum temperature of 28.0 °F (−2.2 °C). Death Valley is the hottest and driest place in North America due to its lack of surface water and low relief. It is so frequently the hottest spot in the United States that many tabulations of the highest daily temperatures in the country omit Death Valley as a matter of course. On the afternoon of July 10, 1913,

850-457: Is available, an abundance of vegetation is usually present. These zones and the adjacent desert support a variety of wildlife species , including 51 species of native mammals , 307 species of birds , 36 species of reptiles , 3 species of amphibians , and 2 species of native fish . Small mammals are more numerous than large mammals, such as bighorn sheep , coyotes , bobcats , kit foxes , cougars , and mule deer . Mule deer are present in

935-625: Is being withdrawn. The highest range within the park is the Panamint Range, with Telescope Peak being its highest point at 11,049 feet (3,368 m). The Death Valley region is a transitional zone in the northernmost part of the Mojave Desert and consists of five mountain ranges removed from the Pacific Ocean. Three of these are significant barriers: the Sierra Nevada , the Argus Range , and

1020-540: Is different from Wikidata All article disambiguation pages All disambiguation pages Death Valley National Park Death Valley National Park is a national park of the United States that straddles the California – Nevada border, east of the Sierra Nevada . The park boundaries include Death Valley , the northern section of Panamint Valley , the southern section of Eureka Valley and most of Saline Valley . The park occupies an interface zone between

1105-536: Is known about the history of the oldest exposed rocks in the area due to extensive metamorphism (alteration of rock by heat and pressure). Radiometric dating gives an age of 1,700 million years for the metamorphism during the Proterozoic . About 1,400 million years ago a mass of granite now in the Panamint Range intruded this complex. Uplift later exposed these rocks to nearly 500 million years of erosion. The Proterozoic sedimentary formations of

1190-606: Is the second-lowest depression in the Western Hemisphere (behind Laguna del Carbón in Argentina ), while Mount Whitney , only 85 miles (137 km) to the west, rises to 14,505 feet (4,421 m) and is the tallest mountain in the contiguous United States . This topographic relief is the greatest elevation gradient in the contiguous United States and is the terminus point of the Great Basin 's southwestern drainage. Although

1275-465: The Borate and Daggett Railroad . The wagons were among the largest ever pulled by draft animals, designed to carry 10 short tons (9 metric tons ) of borax ore at a time. In 1877, six years before twenty-mule teams would be introduced in Death Valley, Scientific American reported that Francis Marion Smith and his brother had shipped their company's borax in a 30-ton load using two large wagons, with

1360-538: The Ediacara fauna and trilobites , the evolution of the latter being part of the Cambrian Explosion of life. The sandy mudflats gave way about 550 million years ago to a carbonate platform (similar to the one around the present-day Bahamas ), which lasted for the next 300 million years of Paleozoic time (refer to the middle of the timescale image ). Death Valley's position was then within ten or twenty degrees of

1445-603: The Golden Gate Bridge dedication, according to "The Last Ride, the Borax Twenty Mule Team 1883–1999". A short item in the June 1940 edition of Desert Magazine mentioned that two of the original borax wagons were en route to the New York World's Fair. The item followed with the note that muleskinner "Borax Bill" Parkinson had driven an original wagon from Oakland, California , to New York City in 1917, spending two years on

1530-530: The Mojave Desert to the nearest railroad spur, 165 miles (266 km) away in Mojave . The routes were from the Harmony and Amargosa Borax Works to Daggett, California , and later Mojave, California . After Harmony and Amargosa shut down in 1888, the mule team's route was moved to the mines at Borate, 3 miles (5 km) east of Calico , back to Daggett. There they worked from 1891 until 1898 when they were replaced by

1615-621: The Nevares Spring People , were hunters and gatherers who arrived in the area perhaps 9,000 years ago (7000 BC) when there were still small lakes in Death Valley and neighboring Panamint Valley. A much milder climate persisted at that time, and large game animals were still plentiful. By 5,000 years ago (3000 BC) the Mesquite Flat People displaced the Nevares Spring People. Around 2,000 years ago

1700-619: The Old Spanish Trail . Called the Bennett-Arcane Party , they were unable to find a pass out of the valley for weeks; they were able to find fresh water at various springs in the area, but were forced to eat several of their oxen to survive. They used the wood of their wagons to cook the meat and make jerky. The place where they did this is today referred to as "Burnt Wagons Camp" and is located near Stovepipe Wells. After abandoning their wagons, they eventually were able to hike out of

1785-472: The Owens River . The large lake that covered much of Death Valley's floor, which geologists call Lake Manly , started to dry up 10,500 years ago. Salt pans and playas were created as ice age glaciers retreated, thus drastically reducing the lakes' water source. Only faint shorelines are left. Habitat varies from salt pan at 282 feet (86 m) below sea level to the sub-alpine conditions found on

1870-513: The Pacific plate along the San Andreas Fault (west of the region), is responsible for the lateral movement. Igneous activity associated with this stretching occurred from 12 million to 4 million years ago. Sedimentation is concentrated in valleys (basins) from material eroded from adjacent ranges. The amount of sediment deposited has roughly kept up with this subsidence, resulting in

1955-541: The Pahrump Group were deposited on these basement rocks. This occurred following uplift and erosion of any earlier sediments from the Proterozoic basement rocks. The Pahrump is composed of arkose conglomerate (quartz clasts in a concrete-like matrix) and mudstone in its lower part, followed by dolomite from carbonate banks topped by algal mats as stromatolites , and finished with basin-filling sediment derived from

2040-534: The Saratoga Spring People moved into the area, which by then was probably already a hot, dry desert. This culture was more advanced at hunting and gathering and was skillful at handcrafts. They also left mysterious stone patterns in the valley. One thousand years ago, the nomadic Timbisha (formerly called Shoshone and also known as Panamint or Koso) moved into the area and hunted game and gathered mesquite beans along with pinyon pine nuts. Because of

2125-672: The United States Weather Bureau recorded a high temperature of 134 °F (57 °C) at Greenland Ranch (now Furnace Creek ) in Death Valley. This temperature stands as the highest ambient air temperature ever recorded at the surface of the Earth. (A report of a temperature of 58 °C (136 °F) recorded in Libya in 1922 was later determined to be inaccurate.) Daily summer temperatures of 120 °F (49 °C) or greater are common, as well as below freezing nightly temperatures in

2210-520: The 1920s where Stovepipe Wells is now located. People flocked to resorts built around natural springs thought to have curative and restorative properties. In 1927, Pacific Coast Borax turned the crew quarters of its Furnace Creek Ranch into a resort, creating the Furnace Creek Inn and resort. The spring at Furnace Creek was harnessed to develop the resort, and as the water was diverted, the surrounding marshes and wetlands started to shrink. Soon

2295-504: The Furnace Creek Formation is the primary source of borate minerals gathered from Death Valley's playas. Other visitors stayed to prospect for and mine deposits of copper , gold , lead , and silver . These sporadic mining ventures were hampered by their remote location and the harsh desert environment. In December 1903, two men from Ballarat were prospecting for silver. One was an out-of-work Irish miner named Jack Keane and

2380-546: The Paleozoic equator . Thick beds of carbonate-rich sediments were periodically interrupted by periods of emergence. Although details of geography varied during this immense interval of time, a north-northeastern coastline trend generally ran from Arizona up through Utah . The resulting eight formations and one group are 20,000 feet (6 km) thick and underlay much of the Cottonwood, Funeral, Grapevine, and Panamint ranges. In

2465-526: The Panamint Range were on top of rocks that would become the Black Mountains and the Cottonwood Mountains. Lateral and vertical transport of these blocks was accomplished by movement on normal faults . Right-lateral movement along strike-slip faults that run parallel to and at the base of the ranges also helped to develop the area. Torsional forces, probably associated with northwesterly movement of

2550-509: The Panamint Range. Air masses tend to lose moisture as they are forced up over mountain ranges, in what climatologists call a rainshadow effect . The exaggerated rain shadow effect for the Death Valley area makes it North America 's driest spot, receiving about 1.5 inches (38 mm) of rainfall annually at Badwater, and some years fail to register any measurable rainfall. Annual average precipitation varies from 1.92 inches (49 mm) overall below sea level to over 15 inches (380 mm) in

2635-570: The above, including possible glacial till from the hypothesized Snowball Earth glaciation. The very youngest rocks in the Pahrump Group are basaltic lava flows. A rift opened and subsequently flooded the region as part of the breakup of the supercontinent Rodinia in the Neoproterozoic (by about 755 million years ago) and the creation of the Pacific Ocean . A shoreline similar to

2720-811: The area from the Colorado River via a long-since dried-up system of rivers and lakes (see Lake Manly ). They now live in two separate populations: one in Salt Creek and another in Cottonball Marsh. Death Valley is one of the hottest and driest places in North America, yet it is home to over 1,000 species of plants ; 23 of which, including the very rare rock lady ( Holmgrenanthe ), are not found anywhere else. Twenty-mule team Twenty-mule teams were teams of eighteen mules and two horses attached to large wagons that transported borax out of Death Valley from 1883 to 1898. They traveled from mines across

2805-402: The area that comprises the park has experienced at least four major periods of extensive volcanism , three or four periods of major sedimentation , and several intervals of major tectonic deformation where the crust has been reshaped. Two periods of glaciation (a series of ice ages) have also had effects on the area, although no glaciers ever existed in the ranges now in the park. Little

2890-697: The area were also the easiest to collect and the most profitable: evaporite deposits such as salts, borate , and talc . Borax was found by Rosie and Aaron Winters near The Ranch at Death Valley (then called Greenland) in 1881. Later that same year, the Eagle Borax Works became Death Valley's first commercial borax operation. William Tell Coleman built the Harmony Borax Works plant and began to process ore in late 1883 or early 1884, continuing until 1888. This mining and smelting company produced borax to make soap and for industrial uses. The end product

2975-472: The area, except for some possibly Jurassic-age volcanic rocks (see the top of the timescale image ). Basin and Range -associated stretching of large parts of crust below southwestern United States and northwestern Mexico started around 16 million years ago and the region is still spreading. This stretching began to affect the Death and Panamint valleys area by 3 million years ago. Before this, rocks now in

3060-456: The arid Great Basin and Mojave deserts, protecting the northwest corner of the Mojave Desert and its diverse environment of salt-flats , sand dunes , badlands , valleys, canyons and mountains. Death Valley is the largest national park in the contiguous United States , as well as the hottest, driest and lowest of all the national parks in the United States. It contains Badwater Basin ,

3145-437: The central extent of Death Valley. The result of this shearing action is additional extension in the central part of Death Valley which causes a slight widening and more subsidence there. Uplift of surrounding mountain ranges and subsidence of the valley floor are both occurring. The uplift on the Black Mountains is so fast that the alluvial fans (fan-shaped deposits at the mouth of canyons) there are small and steep compared to

3230-414: The current Basin and Range landform. Valleys filled with sediment and, during the wet times of glacial periods , with lakes, such as Lake Manly . Death Valley is the fifth-largest American national park and the largest in the contiguous United States . It is also larger than the states of Rhode Island and Delaware combined, and nearly as large as Puerto Rico . In 2013, Death Valley National Park

3315-495: The early-to-mid- Mesozoic the western edge of the North American continent was pushed against the oceanic plate under the Pacific Ocean, creating a subduction zone. A subduction zone is a type of contact between different crustal plates where heavier crust slides below lighter crust. Erupting volcanoes and uplifting mountains were created as a result, and the coastline was pushed to the west. The Sierran Arc started to form to

3400-529: The extreme lack of water in the Great Basin makes this distinction of little current practical use, it does mean that in wetter times the lake that once filled Death Valley ( Lake Manly ) was the last stop for water flowing in the region, meaning the water there was saturated in dissolved materials. Thus, the salt pans in Death Valley are among the largest in the world and are rich in minerals, such as borax and various salts and hydrates . The largest salt pan in

3485-481: The higher mountains that surround the valley. When rain does arrive it often does so in intense storms that cause flash floods which remodel the landscape and sometimes create very shallow ephemeral lakes. The hot, dry climate makes it difficult for soil to form. Mass wasting , the down-slope movement of loose rock, is therefore the dominant erosive force in mountainous areas, resulting in "skeletonized" ranges (mountains with very little soil on them). Sand dunes in

3570-567: The history of the team and the preparation for the Rose Parade outing. There is a photo of Borax Bill driving the team down Broadway in New York City with bells on every animal. Most of the time, only the leaders wore bells. Another picture shows the team in San Francisco in 1917. This picture clearly shows the teamster on a horse. Another historic picture shows a working borax freight team with

3655-524: The huge alluvial fans coming off the Panamint Range . Fast uplift of a mountain range in an arid environment often does not allow its canyons enough time to cut a classic V-shape all the way down to the stream bed. Instead, a V-shape ends at a slot canyon halfway down, forming a 'wine glass canyon.' Sediment is deposited on a small and steep alluvial fan. At 282 feet (86 m) below sea level at its lowest point, Badwater Basin on Death Valley's floor

3740-494: The journey. The mule team also made periodic re-enactment appearances on hauls into Death Valley. In 1958, a twenty-mule team made a symbolic haul out of the new pit at U.S. Borax, commemorating the transition from underground to open-pit mining. Other appearances for twenty-mule teams included President Wilson's inauguration in 1917. Promotional team appearances ended with an outing in the January 1, 1999, Rose Parade. The team had

3825-454: The larger Death Valley springs derive their water from a regional aquifer , which extends as far east as southern Nevada and Utah . Much of the water in this aquifer has been there for many thousands of years, since the Pleistocene ice ages , when the climate was cooler and wetter. Today's drier climate does not provide enough precipitation to recharge the aquifer at the rate at which water

3910-481: The latter four dune fields are accessible only via unpaved roads. Prevailing winds in the winter come from the north, and prevailing winds in the summer come from the south. Thus, the overall position of the dune fields remains more or less fixed. There are rare exceptions to the dry nature of the area. In 2005, an unusually wet winter created a 'lake' in the Badwater Basin and led to the greatest wildflower season in

3995-500: The local Chamber of Commerce estimates that 6,000 people are moving to the city every month. Between 1985 and 1995, the population of the Las Vegas Valley increased from 550,700 to 1,138,800. In 1977, parts of Death Valley were used by director George Lucas as a filming location for Star Wars , providing the setting for the fictional planet Tatooine . The park has a diverse and complex geologic history. Since its formation,

4080-400: The mountain ridges where they harvested pine nuts before moving back to the valley bottom for winter. The California Gold Rush brought the first people of European descent known to visit the immediate area. In December 1849 two groups of California Gold Country -bound travelers with perhaps 100 wagons total stumbled into Death Valley after getting lost on what they thought was a shortcut off

4165-583: The national monument. The public outcry that ensued led to greater protection for all national park and monument areas in the United States. In 1976, Congress passed the Mining in the Parks Act, which closed Death Valley National Monument to the filing of new mining claims, banned open-pit mining and required the National Park Service to examine the validity of tens of thousands of pre-1976 mining claims. Mining

4250-588: The night stops. Francis Marion Smith , who came to be known as "Borax Smith", founded Pacific Borax. Cora Keagle recounted his history in an article, "Buckboard Days in Borate", published in Desert Magazine in September 1939. Smith was a great promoter and sent drivers out with jerk-line teams to major U.S. cities to promote the company's laundry product with free samples. The exhibition teams were typically mules for

4335-444: The northwest from heat and pressure generated from subduction, and compressive forces caused thrust faults to develop. A long period of uplift and erosion was concurrent with and followed the above events, creating a major unconformity, which is a large gap in the geologic record. Sediments worn off the Death Valley region were carried both east and west by wind and water. No Jurassic- to Eocene -aged sedimentary formations exist in

4420-412: The oldest rocks being extensively metamorphosed and at least 1.7 billion years old. Ancient, warm, shallow seas deposited marine sediments until rifting opened the Pacific Ocean . Additional sedimentation occurred until a subduction zone formed off the coast. The subduction uplifted the region out of the sea and created a line of volcanoes . Later the crust started to pull apart, creating

4505-572: The other was a one-eyed Basque butcher named Domingo Etcharren. Quite by accident, Keane discovered an immense ledge of free-milling gold by the duo's work site and named the claim the Keane Wonder Mine . This started a minor and short-lived gold rush into the area. The Keane Wonder Mine, along with mines at Rhyolite , Skidoo and Harrisburg , were the only ones to extract enough metal ore to make them worthwhile. Outright shams such as Leadfield also occurred, but most ventures quickly ended after

4590-625: The park extends 40 miles (64 km) from the Ashford Mill Site to the Salt Creek Hills, covering some 200 square miles (520 km ) of the valley floor. The best known playa in the park is the Racetrack , known for its moving rocks. According to the Köppen climate classification system, Death Valley National Park has a hot desert climate ( BWh ). The plant hardiness zone at Badwater Basin

4675-545: The park's history. In October 2015, a "1000 year flood event" with over three inches of rain caused major damage in Death Valley National Park. A similar widespread storm in August 2022 damaged pavement and deposited debris on nearly every road, trapping 1,000 residents and visitors overnight. Four Native American cultures are known to have lived in the area during the last 10,000 years. The first known group,

4760-640: The park, and some of the highest in North America, are located in the Eureka Valley about 50 miles (80 km) to the north of Stovepipe Wells, while the Panamint Valley dunes and the Saline Valley dunes are located west and northwest of the town, respectively. The Ibex dune field is near the seldom-visited Ibex Hill in the southernmost part of the park, just south of the Saratoga Springs marshland. All

4845-431: The park, while famous, are not nearly as widespread as their fame or the dryness of the area may suggest. The Mesquite Flat dune field is the most easily accessible from the paved road just east of Stovepipe Wells in the north-central part of the valley and is primarily made of quartz sand. Another dune field is just 10 miles (16 km) to the north but is instead mostly composed of travertine sand. The highest dunes in

4930-401: The park. Many of the larger cities and towns within the boundary of the regional groundwater flow system that the park and its plants and animals rely upon are experiencing some of the fastest growth rates of any place in the United States. Notable examples within a 100-mile (160 km) radius of Death Valley National Park include Las Vegas and Pahrump, Nevada . In the case of Las Vegas,

5015-556: The pinyon/juniper associations of the Grapevine, Cottonwood, and Panamint ranges. Bighorn sheep are a rare species of mountain-dwelling sheep that exist in isolated bands in the Sierra and in Death Valley. These are highly adaptable animals and can eat almost any plant. They have no known predators, but humans and burros compete for habitat. The ancestors of the Death Valley pupfish swam to

5100-519: The present Atlantic Ocean margin of the United States lay to the east. An algal mat -covered carbonate bank was deposited, forming the Noonday Dolomite. Subsidence of the region occurred as the continental crust thinned and the newly formed Pacific widened, forming the Ibex Formation. An angular unconformity (an uneven gap in the geologic record) followed. A true ocean basin developed to

5185-458: The promotion value, but Smith explained that in actual use, wheel horses were a standard practice. Outside contractors hauling for the company typically used mixed teams. Joe Zentner wrote of the origins of the advertising campaign on the Desert USA website in "Twenty Mule Teams on the move in Death Valley". Bill Parkinson, formerly a night watchman for the company, had to learn quickly how to drive

SECTION 60

5270-501: The retention of more or less the same valley floor elevation over time. Pleistocene ice ages started 2 million years ago, and melt from alpine glaciers on the nearby Sierra Nevada Mountains fed a series of lakes that filled Death and Panamint valleys and surrounding basins (see the top of the timescale image ). The lake that filled Death Valley was the last of a chain of lakes fed by the Amargosa and Mojave Rivers , and possibly also

5355-459: The second-lowest point in the Western Hemisphere and lowest in North America at 282 feet (86 m) below sea level. More than 93% of the park is a designated wilderness area . The park is home to many species of plants and animals which have adapted to the harsh desert environment including creosote bush , Joshua tree , bighorn sheep , coyote , and the endangered Death Valley pupfish ,

5440-414: The subject of books, radio programs, television series, and movies. Tourism expanded in the 1920s when resorts were built around Stovepipe Wells and Furnace Creek . Death Valley National Monument was declared in 1933 and the park was substantially expanded and became a national park in 1994. The natural environment of the area has been shaped largely by its geology. The valley is actually a graben with

5525-434: The summit of Telescope Peak, which rises to 11,049 feet (3,368 m). Vegetation zones include creosote bush , desert holly , and mesquite at the lower elevations and sage up through shadscale , blackbrush , Joshua tree , pinyon - juniper , to limber pine and bristlecone pine woodlands. The salt pan is devoid of vegetation, and the rest of the valley floor and lower slopes have sparse cover, although where water

5610-429: The team when he was given the role of "Borax Bill". He was the first, but not the last, driver known by that name. The 1904 St. Louis World's Fair was the maiden appearance for the team and was such a success that Parkinson went on tour. The team eventually made its way to New York City, parading down Broadway. After that showing, the mules were sold, and the wagons shipped back to California. The mules also appeared at

5695-494: The team with a single long rein, known as a "jerk line", and the aid of a long blacksnake whip. The teamster usually rode the left wheeler, but he could also drive from the trailer seat, working the brake on steep descents. The swamper usually rode the trailer, but in hilly country, he would be on the back action available to work the brake. From the trailer, armed with a can of small rocks, he could pelt an inattentive mule and send it back to work. Both men were responsible for readying

5780-434: The team, feeding and watering of the mules, and any veterinary care or repairs that needed to be done. There was a mid-day stop to feed and water the mules in harness. The night stops had corrals and feed boxes for the mules. A day's travel averaged about 17 miles (27 km), varying slightly from leg to leg. It took about ten days to make a trip one way. Cabins were constructed by the company for use of drivers and swampers at

5865-528: The use of mules and horses. In "Of Myths and Men: Separating Fact from Fiction in the Twenty Mule Team Story", author Ted Fave discussed how the teams were assembled, trained, and used. "Nadeau's Freighting Teams in the Mojave", based on Remi Nadeau's historic accomplishments hauling freight throughout the desert region, gives further insight as to the superiority of mules for general use. The teamster drove

5950-431: The valley in 1849 while looking for a shortcut to the gold fields of California , gave this valley its grim name, even though only one of their group died there. Several short-lived boom towns sprang up during the late 19th and early 20th centuries to mine gold and silver. The only long-term profitable ore to be mined was borax , which was transported out of the valley with twenty-mule teams . The valley later became

6035-481: The valley was a popular winter destination. Other facilities started off as private getaways but were later opened to the public. Most notable among these was Death Valley Ranch, better known as Scotty's Castle . This large ranch home built in the Spanish Revival style became a hotel in the late 1930s and, largely because of the fame of Death Valley Scotty , a tourist attraction. Death Valley Scotty, whose real name

6120-421: The valley. Just after leaving the valley, one of the women in the group turned and said, "Goodbye Death Valley," giving the valley its name. Included in the party was William Lewis Manly whose autobiographical book Death Valley in '49 detailed this trek and popularized the area (geologists later named the prehistoric lake that once filled the valley after him). The ores that are most famously associated with

6205-573: The wagon's image to promote the Boraxo brand of granular hand soap and the Death Valley Days radio and television programs. In 1914, the Death Valley Railroad was built to serve mining operations on the east side of the valley. Mining continued after the collapse of Coleman's empire, and by the late 1920s the area was the world's number one source of borax. Some four to six million years old,

6290-499: The wagons and were typically larger than their mule brethren. They had great brute strength for starting the wagons moving and could withstand the jarring of the heavy wagon tongue, but the mules were smarter and better suited to work in desert conditions. In the Proceedings Fifth Death Valley Conference on History and Prehistory , two articles discussed freight operations in the Mojave with specific details on

6375-425: The wagons for the teamster and the swamper . Water supplies were refilled at springs along the way, as it was not possible to carry enough water for the entire trip. Feed and water for the return trip were dispersed at camps along the road by outbound teams from Mojave pulling empty borax wagons. At one point on the route an additional 500-US-gallon (1,900 L) wagon was added to the outbound train to take water to

6460-411: The west, breaking all the earlier formations along a steep front. A wedge of clastic sediment then began to accumulate at the base of the two underwater precipices, starting the formation of opposing continental shelves . Three formations developed from sediment that accumulated on the wedge. The region's first known fossils of complex life are found in the resulting formations. Notable among these are

6545-463: The wide altitude differential between the valley bottom and the mountain ridges, especially on the west, the Timbisha practiced a vertical migration pattern. Their winter camps were located near water sources in the valley bottoms. As the spring and summer progressed and the weather warmed, grasses and other plant food sources ripened at progressively higher altitudes. November found them at the very top of

6630-587: The winter. July is the hottest month, with an average high of 117 °F (47 °C) and an average low of 91 °F (33 °C). December is the coldest month, with an average high of 66 °F (19 °C) and an average low of 41 °F (5 °C). The record low is 15 °F (−9.4 °C). There are an average of 197.3 days annually with highs of 90 °F (32.2 °C) or higher and 146.9 days annually with highs of 100 °F (37.8 °C) or higher. Freezing temperatures of 32 °F (0 °C) or lower occur on an average of 8.6 days annually. Several of

6715-420: Was Walter Scott, was a gold miner who pretended to be the owner of "his castle", which he claimed to have built with profits from his gold mine. Neither claim was true, but the real owner, Chicago millionaire Albert Mussey Johnson , encouraged the myth. When asked by reporters what his connection was to Walter Scott's castle, Johnson replied that he was Mr. Scott's banker. President Herbert Hoover proclaimed

6800-459: Was allowed to resume on a limited basis in 1980 with stricter environmental standards. The last mine in the park, Billie Mine, closed in 2005. In 1952 President Harry Truman added the Devils Hole to Death Valley National Monument; it is the only habitat of the Devils Hole pupfish . Death Valley National Monument was designated a biosphere reserve in 1984. On October 31, 1994, the monument

6885-545: Was designated as a dark sky park by the International Dark-Sky Association . There are two major valleys in the park, Death Valley and Panamint Valley . Both of these valleys were formed within the last few million years and both are bounded by north–south-trending mountain ranges . These and adjacent valleys follow the general trend of Basin and Range topography with one modification: there are parallel strike-slip faults that perpendicularly bound

6970-574: Was expanded by 1.3 million acres (5,300 km ) and re-designated as a national park , via congressional passage of the California Desert Protection Act (Public Law 103–433). Consequently, the elevated status for Death Valley made it the largest national park in the contiguous United States . On March 12, 2019, the John D. Dingell, Jr. Conservation, Management, and Recreation Act added 35,292 acres (55 sq mi; 143 km ) to

7055-485: Was quickly reopened to mining by Congressional action in June 1933. As improvements in mining technology allowed lower grades of ore to be processed, and new heavy equipment allowed greater amounts of rock to be moved, mining in Death Valley changed. Gone were the days of the "single-blanket, jackass prospector" long associated with the romantic west. Open pit and strip mines scarred the landscape as international mining corporations bought claims in highly visible areas of

7140-512: Was shipped out of the valley 165 miles (266 km) to the Mojave railhead in 10-ton-capacity wagons pulled by " twenty-mule teams " that were actually teams of 18 mules and two horses each. The teams averaged two miles (3.2 km) an hour and required about 30 days to complete a round trip. The trade name 20-Mule Team Borax was established by Francis Marion Smith 's Pacific Coast Borax Company after Smith acquired Coleman's borax holdings in 1890. A memorable advertising campaign used

7225-449: Was the trailer, the second was "the tender" or the "back action", and the tank wagon containing water brought up the rear. With the mules, the caravan stretched over 180 feet (55 m). When loaded with ore the total weight of the mule train, wagons and all, was 73,200 pounds (33,200 kg; 36.6 short tons). The water tank held 1,200 US gallons (4,500 L), and supplied the mules with water en route. There were water barrels on
