140-642: From the late 19th century through the early 20th century the term was used to refer to the portion of the Appalachian Mountain range located within Maine. In the late 18th century and early 19th century, this was one of the areas of disputed boundary between the United States and Canada. This lack of a clear boundary in this area and further east in Maine, led to the Aroostook War , the only war ever declared by

280-634: A U.S. state on a foreign country. "Maine Highlands" continued to be used to describe that portion of the border region running through the mountains at least until 1916. The Highlands lie within the New England-Acadian forests ecoregion . Four border crossing stations serve the Canada–United States border in the region. This Maine state location article is a stub . You can help Misplaced Pages by expanding it . Appalachian Mountains The Appalachian Mountains , often called

420-461: A campsite. Hikers also create their own community while on the trail. Many hikers create long lasting friendships while on the trail. Conversations are easily started because of the common interest of hiking . The Appalachian Trail is relatively safe. Most injuries or incidents are consistent with comparable outdoor activities. Most hazards are related to weather conditions, human error, plants, animals, diseases, and hostile humans encountered along

560-463: A fragile ecosystem known as the Southern Appalachian spruce–fir forest . Fraser fir rarely occurs below 5,500 ft (1,700 m), and becomes the dominant tree type at 6,200 ft (1,900 m). By contrast, balsam fir is found from near sea level to the tree line in the northern Appalachians, but ranges only as far south as Virginia and West Virginia in the central Appalachians, where it

700-424: A great deal of attention to the project by publicizing the first claimed thru-hike. The claim was later criticized for the hike's omission of significant portions due to shortcuts and car rides. Shaffer later claimed the first north-to-south thru-hike, the first to claim to do so in each direction. Chester Dziengielewski was later named the first southbound thru-hiker. In 1998, Shaffer, nearly 80 years old, hiked

840-713: A great thickness of sediment accumulated. Eventually, the tectonic forces pulling the two continents apart became so strong that an ocean formed off the eastern coast of the Laurentian margin. This was called the Iapetus Ocean and was the precursor of the modern Atlantic Ocean. The rocks of the Valley and Ridge province formed over millions of years, in the Iapetus. Shells and other hard parts of ancient marine plants and animals accumulated to form limey deposits that later became limestone. This

980-662: A hiker visiting from England was killed on the trail by falling while taking photos at the Annapolis Rocks overlook in Maryland. The 2020 COVID-19 pandemic prompted the Appalachian Trail Conservancy to discourage use of the trail and the National Park Service to close all AT-managed hiking shelters from Virginia to Maine. The withdrawal of volunteers and trail-maintenance crews left the trail unprepared for

1120-737: A hiker was killed on the trail in Maryland when a large tree blew over and fell onto him. Violent crime is rare but has occurred in a few instances. The first reported homicide on the trail was in 1974 in Georgia. In 1981, the issue of violence on the Appalachian Trail received national attention when Robert Mountford, Jr. and Laura Susan Ramsay, both social workers in Ellsworth, Maine , were murdered by Randall Lee Smith . Another homicide occurred in May 1996, when two women were abducted, bound and murdered near

1260-499: A name for the tribe and region spreading well inland to the north. Pánfilo de Narváez 's expedition first entered Apalachee territory on June 15, 1528, and applied the name. Now spelled "Appalachian", it is the fourth-oldest surviving European place-name in the US. After the 1540 expedition of Hernando de Soto , Spanish cartographers began to apply the name of the tribe to the mountains themselves. The first cartographic appearance of Apalchen

1400-656: A new ocean opened up, the Rheic Ocean , during the Middle to Late Devonian, and subsequently its closure would result in the formation of the Alleghanian orogeny . As the continental plates moved closer together, fragments of oceanic crust, islands, and other continental masses collided with the eastern margin of ancestral North America. By this time, plants had appeared on land, followed by scorpions, insects, and amphibians. The ocean continued to shrink until, about 270 million years ago,

1540-504: A number of deciduous rhododendrons (azaleas), and smaller heaths such as teaberry ( Gaultheria procumbens ) and trailing arbutus ( Epigaea repens ). The evergreen great rhododendron ( Rhododendron maximum ) is characteristic of moist stream valleys. These occurrences are in line with the prevailing acidic character of most oak forest soils. In contrast, the much rarer chinquapin oak ( Quercus muehlenbergii ) demands alkaline soils and generally grows where limestone rock

1680-444: A number of serious insect and disease outbreaks. Among the most conspicuous is that of the introduced spongy moth ( Lymantria dispar ), which infests primarily oaks, causing severe defoliation and tree mortality. But it also has the benefit of eliminating weak individuals, and thus improving the genetic stock, as well as creating rich habitat of a type through accumulation of dead wood. Because hardwoods sprout so readily, this moth

1820-468: A reference to yellow road stripes, is given to those who hitchhike to move either down or up the trail. Part of hiker subculture includes making colorful entries in logbooks at trail shelters, signed using pseudonyms called "trail names". The Appalachian Trail Conservancy gives the name "2000 Miler" to anyone who completes the entire trail. The ATC's recognition policy for "2000 Milers" gives equal recognition to thru-hikers and section-hikers, operates on

1960-491: A system of communication for a network of hikers along the trail. Shelter logs—entries written in log books at certain shelters—can provide proof of who summits certain mountains and can warn about dangerous animals or unfriendly people in the area. Hikers may cite when a certain water source is dried up, providing crucial information to other hikers. In addition to official shelters, many people offer their homes, places of business, or inns to accommodate AT hikers. One example

2100-539: A variety of oaks ( Quercus spp.), hickories ( Carya spp.) and, in the past, by the American chestnut ( Castanea dentata ). The American chestnut was virtually eliminated as a canopy species by the introduced fungal chestnut blight ( Cryphonectaria parasitica ), but lives on as sapling-sized sprouts that originate from roots, which are not killed by the fungus. In present-day forest canopies, chestnut has been largely replaced by oaks. The oak forests of

2240-558: A variety of other destructive activities continue, albeit in diminished forms; and thus far only a few ecologically based management practices have taken hold. Appalachian bogs are boreal ecosystems , which occur in many places in the Appalachians, particularly the Allegheny and Blue Ridge subranges. Though popularly called bogs , many of them are technically fens . Appalachian Trail The Appalachian Trail , also called

2380-585: A wooden floor, although some shelters are much more complex in structure. Shelters are usually spaced a day's hike or less apart, most often near a water source (which may be dry) and with a privy . They generally have spaces for tent sites in the vicinity as the shelters may be full. The Appalachian Mountain Club (AMC) operates a system of eight huts along 56 miles (90 km) of New Hampshire's White Mountains. These huts are significantly larger than standard trail shelters and offer full-service lodging and meals during

2520-483: Is a boreal species that forms a few high elevation outliers as far south as West Virginia. All of these species except white pine tend to occupy sandy, rocky, poor soil sites, which are mostly acidic in character. White pine, a large species valued for its timber, tends to do best in rich, moist soil, either acidic or alkaline in character. Pitch pine is also at home in acidic, boggy soil, and Table Mountain pine may occasionally be found in this habitat as well. Shortleaf pine

2660-485: Is a separate trail and not an official extension of the Appalachian Trail. Other branches are designated in parts of Nova Scotia, Prince Edward Island, and along the western shore of Newfoundland, to the northern end of the Appalachian Mountain range , where it enters the Atlantic Ocean, near L'Anse aux Meadows National Historic Site . The route has since been extended to Greenland , Europe , and Morocco . Although

2800-533: Is far more prevalent along the trail than true alpine conditions. While it mainly exists in the north, a few mountains in the south have subalpine environments, which are typically coated in an ecosystem known as the Southern Appalachian spruce-fir forest . Southern ranges and mountains where sub-alpine environments occur include the Great Smoky Mountains , where sub-alpine environments only begin around 6,000 feet (1,800 m) in elevation, Roan Highlands on

2940-403: Is found at high elevations in the northern Appalachians, and in bogs as far south as Pennsylvania. The Appalachians are also home to two species of fir, the boreal balsam fir ( Abies balsamea ), and the southern high elevation endemic, Fraser fir ( Abies fraseri ). Fraser fir is endemic to the highest parts of the southern Appalachian Mountains, where along with red spruce it forms

3080-533: Is generally found in warmer habitats and at lower elevations than the other species. All the species listed do best in open or lightly shaded habitats, although white pine also thrives in shady coves, valleys, and on floodplains. The Appalachians are characterized by a wealth of large, beautiful deciduous broadleaf (hardwood) trees. Their occurrences are best summarized and described in E. Lucy Braun 's 1950 classic, Deciduous Forests of Eastern North America (Macmillan, New York). The most diverse and richest forests are

3220-594: Is made up of maples, birch and beech , with colorful foliage displays in September and October. While the vast majority of lowland forest south of the White Mountains is hardwood, many areas have some coniferous trees as well, and in Maine, these often grow at low elevations. There is a drastic change between the lowland and subalpine , evergreen forest, as well as another, higher break, at tree line , above which only hardy alpine plants grow. The sub-alpine region

3360-414: Is near the surface. Hence no ericaceous shrubs are associated with it. The Appalachian flora also include a diverse assemblage of bryophytes (mosses and liverworts), as well as fungi . Some species are rare and/or endemic. As with vascular plants , these tend to be closely related to the character of the soils and the thermal environment in which they are found. Eastern deciduous forests are subject to

3500-519: Is not as harmful as the hemlock woolly adelgid . Perhaps more serious is the introduced beech bark disease complex, which includes both a scale insect ( Cryptococcus fagisuga ) and fungal components. During the 19th and early 20th centuries, the Appalachian forests were subject to severe and destructive logging and land clearing, which resulted in the designation of the national forests and parks as well many state-protected areas. However, these and

3640-517: Is now the southern United States, the Ococee Basin was formed. Seawater filled the basin. Rivers from the surrounding countryside carried clay, silt, sand, and gravel to the basin, much as rivers today carry sediment from the midcontinent region to the Gulf of Mexico. The sediment spread out in layers on the basin floor. The basin continued to subside, and over a long period of time, probably millions of years,

3780-469: Is on Diego Gutiérrez 's map of 1562; the first use for the mountain range is the map of Jacques le Moyne de Morgues in 1565. The name was not commonly used for the whole mountain range until the late 19th century. A competing and often more popular name was the "Allegheny Mountains", "Alleghenies", and even "Alleghania". In the early 19th century, Washington Irving proposed renaming the United States either Appalachia or Alleghania. In U.S. dialects in

3920-767: Is only around 3,500 feet (1,100 m). This elevation in Massachusetts would barely be a subalpine region, and, south of Virginia, consists of lowland forest. This illustrates the drastic change in climate over 2,000 miles (3,200 km). Bicycles are prohibited from most of the trail, except for the sections that follow the Chesapeake and Ohio Canal (C&O Canal) in Maryland and the Virginia Creeper Trail in Virginia . Horses and pack animals are prohibited except horses on

4060-535: Is possible that the cratons of Kalahari , and Rio Plato , were also part of that early collision since they were present as Rodinia broke up). Mountain-building referred to as the Grenville Orogeny occurred along the boundaries of the cratons. The present Appalachian Mountains have at least two areas which are made from rock formations that were formed during this orogeny - the Blue Ridge Mountains and

4200-638: Is sometimes termed the Appalachian orogeny , writing communities struggle to agree on an encyclopedic definition of the mountain range. However, each of the governments has an agency that informs the public about the major landforms that make up the countries, the United States Geological Survey (USGS) and the Geological Survey of Canada (GSC). The landforms are referred to as physiographic regions. The regions create precise boundaries from which maps can be drawn. The Appalachian Highlands

4340-645: Is subject to the hemlock woolly adelgid ( Adelges tsugae ), an introduced insect, that is rapidly extirpating it as a forest tree. Less abundant, and restricted to the southern Appalachians, is Carolina hemlock ( Tsuga caroliniana ). Like Canada hemlock, this tree suffers severely from the hemlock woolly adelgid. Several species of pines characteristic of the Appalachians are eastern white pine ( Pinus strobus ), Virginia pine ( Pinus virginiana ), pitch pine ( Pinus rigida ), Table Mountain pine ( Pinus pungens ) and shortleaf pine ( Pinus echinata ). Red pine ( Pinus resinosa )

4480-548: Is the Little Lyford Pond camps maintained by the Appalachian Mountain Club. Inns are more common in sections of the trail that coincide with national parks, most notably Virginia's Shenandoah National Park. The trail crosses many roads, providing opportunity for hikers to hitchhike into town for food and other supplies. The Appalachian Trail Conservancy lists over 40 communities that have qualified as part of

4620-439: Is the largest omnivore that may be encountered on the trail, and it inhabits all regions of the Appalachians. Bear sightings on the trail are uncommon, except in certain sections, especially Shenandoah National Park and portions of New Jersey, New York, Connecticut, and Massachusetts sections, where bear populations have increased steadily since 1980; confrontations are rarer still. Other hazards include venomous snakes, including

4760-456: Is the name of one of the eight physiographic regions of the contiguous 48 United States. The Appalachian Uplands is the name of one of seven physiographic regions of Canada. The second level in the physiographic classification schema for the USGS is "province", the same word as Canada uses to divide its political subdivisions, meaning that the terminology used by the two countries do not match below

4900-506: Is the same process by which limestone forms in modern oceans. The weathering of limestone, now exposed at the land surface, produces the lime-rich soils that are so prevalent in the fertile farmland of the Valley and Ridge province. During this continental break-up, around 600 million to 560 million years ago, volcanic activity was present along the tectonic margins. There is evidence of this activity in today's Blue Ridge Mountains. Mount Rogers , Whitetop Mountain , and Pine Mountain are all

5040-459: Is usually confined above 3,900 ft (1,200 m) asl, except in cold valleys. Curiously, it is associated with oaks in Virginia. The balsam fir of Virginia and West Virginia is thought by some to be a natural hybrid between the more northern variety and Fraser fir. While red spruce is common in both upland and bog habitats, balsam fir, as well as black spruce and tamarack, are more characteristic of

5180-571: The A.T. , is a hiking trail in the Eastern United States , extending almost 2,200 miles (3,540 km) between Springer Mountain in Georgia and Mount Katahdin in Maine, and passing through 14 states. The Appalachian Trail Conservancy claims the Appalachian Trail to be the world's longest hiking-only trail. More than three million people hike segments of it each year. The trail was first proposed in 1921 and completed in 1937. Improvements and changes have continued since then. It became

5320-611: The Adirondacks . After the Grenville orogeny, the direction of the continental drift reversed, and the single supercontinent Rodinia began to break up. The mountains formed during the Grenvillian era underwent erosion due to weathering, glaciation, and other natural processes, resulting in the leveling of the landscape. The eroded sediments from these mountains contributed to the formation of sedimentary basins and valleys. For example, in what

The Appalachian Mountains are a barrier to east–west travel, as they form a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east–west. This barrier was extremely important in shaping the expansion of the United States in

5600-843: The Appalachian National Scenic Trail under the National Trails System Act of 1968. The trail is maintained by 31 trail clubs and multiple partnerships and managed by the National Park Service , United States Forest Service , and the nonprofit Appalachian Trail Conservancy. Most of the trail is in forest or wild lands, but some parts traverse towns, roads, and farms. From south to north it passes through Georgia , North Carolina , Tennessee , Virginia , West Virginia , Maryland , Pennsylvania , New Jersey , New York , Connecticut , Massachusetts , Vermont , New Hampshire , and Maine .

In the central section, north of the New River, the rivers, rising in or just beyond the Valley Ridges, flow through great gorges to the Great Valley, and then across the Blue Ridge to tidal estuaries penetrating the coastal plain via the Roanoke River, James River , Potomac River , and Susquehanna River . In the northern section the height of land lies on the inland side of

6160-704: The Iapetus Ocean , from the North America/Europe collision (See Caledonian orogeny ). By the end of the Mesozoic Era , the Appalachian Mountains had been eroded to an almost flat plain. It was not until the region was uplifted during the Cenozoic Era that the distinctive topography of the present formed. Uplift rejuvenated the streams, which rapidly responded by cutting downward into the ancient bedrock. Some streams flowed along weak layers that define

6300-594: The National Forest service actually mows the grasses periodically in order to keep the balds free of trees. There are no subalpine regions between Mount Rogers in Virginia and Mount Greylock in Massachusetts , mainly because the trail stays below 3,000 feet (910 m) from Shenandoah National Park in Virginia to Mount Greylock. But Mount Greylock has a large subalpine region, the only such forest in Massachusetts, extending down to 3,000 feet (910 m), which in

Thrust faulting uplifted and warped older sedimentary rock laid down on the passive margin. As the mountains rose, erosion began to wear them down over time. Streams carried rock debris downslope to be deposited in nearby lowlands. The Taconic orogeny ended after about 60 million years, but built much of

6720-626: The North Carolina - Tennessee border, where sub-alpine growth descends below 6,000 feet (1,800 m), and Mount Rogers and the Grayson Highlands in Virginia , where there is some alpine growth above 5,000 feet (1,500 m). Appalachian balds are also found in the Southern highlands, and are believed to occur due to fires or grazing in recent centuries, or in some cases due to thin, sandy soils. Several balds are sprouting trees, and on some,

6860-543: The Rocky Mountains of the west. Some of the outcrops in the Appalachians contain rocks formed during the Precambrian era. The geologic processes that led to the formation of the Appalachian Mountains started 1.1 billion years ago. The first mountain range in the region was created when the continents of Laurentia and Amazonia collided, creating a supercontinent called Rodinia . The collision of these continents caused

7000-569: The Shenandoah region of Virginia. Shelters are generally maintained by local volunteers. Almost all shelters have one or more pre-hung food hangers (generally consisting of a short nylon cord with an upside-down tuna can suspended halfway down its length) where hikers can hang their food bags to keep them out of the reach of rodents. In hiker lingo, these are sometimes called "mouse trapezes". Most shelters also contain "unofficial registries", which are known as shelter logs. These logs usually come in

7140-615: The Smoky Mountains ; and moose , which may be found in the vicinity of Massachusetts and northward. Small mammal species that inhabit along the trails are beaver , squirrel , river otter , chipmunk , porcupine , bobcat , two species of fox , boar , woodchuck , raccoon , and coyote . Bird species that reside in the trails are wild turkey , ruffed grouse , mourning dove , raven , two species of eagle , wood duck , three species of owl , and three species of hawk as well as warblers . There are different kinds of squirrels along

7280-518: The Triple Crown of Hiking in the United States. The trail was conceived by Benton MacKaye , a forester who wrote his original plan—called "An Appalachian Trail, A Project in Regional Planning" —shortly after his wife's death in 1921. MacKaye's idea detailed a grand trail that would connect a series of farms and wilderness work/study camps for city-dwellers along the Appalachian Mountains from

7420-499: The White Mountains in New Hampshire , it often occurs well below 3,000 feet (910 m). At Mount Moosilauke , which summits at 4,802 feet (1,464 m), the first alpine environment on the trail is reached, where only thin, sporadic flora are interspersed with bare rocks. Between the two regions is the krummholz region, where stunted trees grow with their branches oriented away from the winter's prevailing northwest wind, giving

7560-706: The eastern seaboard of the United States and the Midwest region of the country. The Eastern Continental Divide follows the Appalachian Mountains from Pennsylvania to Georgia. The Appalachians, particularly the Central and Southern regions, is one of the most biodiverse places in North America. The north–south orientation of the long ridges and valleys contributes to the high number of plant and animal species. Species were able to migrate through these from either direction during alternating periods of warming and cooling, settling in

7700-1546: The mixed-mesophytic or medium-moisture types, which are largely confined to rich, moist montane soils of the southern and central Appalachians, particularly in the Cumberland and Allegheny Mountains, but also thrive in the southern Appalachian coves. Characteristic canopy species are white basswood ( Tilia heterophylla ), yellow buckeye ( Aesculus octandra ), sugar maple ( Acer saccharum ), American beech ( Fagus grandifolia ), tuliptree ( Liriodendron tulipifera ), white ash ( Fraxinus americana ) and yellow birch ( Betula alleganiensis ). Other common trees are red maple ( Acer rubrum ), shagbark and bitternut hickories ( Carya ovata and C. cordiformis ) and black or sweet birch ( Betula lenta ). Small understory trees and shrubs include paw paw ( Asimina tribola ), flowering dogwood ( Cornus florida ), hophornbeam ( Ostrya virginiana ), witch-hazel ( Hamamelis virginiana ) and spicebush ( Lindera benzoin ). There are also hundreds of perennial and annual herbs, among them such herbal and medicinal plants as American ginseng ( Panax quinquefolius ), goldenseal ( Hydrastis canadensis ), bloodroot ( Sanguinaria canadensis ) and black cohosh ( Cimicifuga racemosa ). The foregoing trees, shrubs, and herbs are also more widely distributed in less rich mesic forests that generally occupy coves, stream valleys and flood plains throughout

7840-578: The 1920s. Fink was inducted into the Appalachian Trail Hall of Fame in 2019. In 1922, only a year after MacKaye's article proposing an Appalachian Trail was written, Fink began corresponding with hiking leaders in New England about building the Trail. When Avery began planning the Trail's route in the south, Fink was the first person he contacted. Many of the trail's present highlights were not part of

10080-658: The Georgia to New Hampshire trail should, in the future, extend to Katahdin, and "then to Birmingham, Alabama". As of March 2015 , The Pinhoti Trail terminates at the base of Flagg Mountain, near Weogufka in Coosa County , 50 miles (80 km) east of Birmingham. In 2010, the Alabama state legislature formed the Alabama Appalachian Mountain Trail Commission to provide state resources for trail improvements, although officially designating Pinhoti as part of

10220-820: The Great Balsams. The Western Blue Ridge Front is subdivided into the Unaka Range , the Bald Mountains , the Great Smoky Mountains , and the Unicoi Mountains , and its major peaks include Roan Mountain 6,285 ft (1,916 m) in the Unakas, Big Bald 5,516 ft (1,681 m) and Max Patch 4,616 ft (1,407 m) in the Bald Mountains, Kuwohi 6,643 ft (2,025 m), Mount Le Conte 6,593 feet (2,010 m), and Mount Guyot 6,621 ft (2,018 m) in

10360-727: The Great Smokies, and Big Frog Mountain 4,224 ft (1,287 m) near the Tennessee- Georgia -North Carolina border. Prominent summits in the cross ridges include Waterrock Knob (6,292 ft (1,918 m)) in the Plott Balsams . Across northern Georgia, numerous peaks exceed 4,000 ft (1,200 m), including Brasstown Bald , the state's highest, at 4,784-and-4,696 ft (1,458-and-1,431 m) Rabun Bald . In north-central Alabama , Mount Cheaha rises prominently to 1,445 feet (440 m) over its surroundings, as part of

10500-521: The Hopper (a glacial cirque westward of the trail as it traverses Mt. Greylock in Massachusetts), and "The Hermitage", near Gulf Hagas in Maine. In the south, the forest is dominated by hardwoods, including oak and tulip trees , also known as yellow poplar. Farther north, tulip trees are gradually replaced by maples and birches . Oaks begin to disappear in Massachusetts. By Vermont, the lowland forest

10640-579: The U.S./Canadian border, the St. Lawrence Valley area is handled differently in the physiographic classification schemas. The part of the St. Lawrence Valley in the United States is one of the second-level classifications, part of the Appalachian Highlands. In Canada, the area is part of the first-level classification, the St. Lawrence Lowlands . This includes the area around the city of Montreal, Anticosti Island , and

10780-619: The appearance of flags; they are sometimes called "flag trees". This region resembles lowland terrain hundreds of miles north in Canada. It also contains many endangered and threatened species. The trail has been rerouted over New Hampshire's Presidential Range so the Appalachian Mountain Club can protect certain plant life. The alpine cutoff in the Whites is generally between 4,200 and 4,800 feet (1,300 and 1,500 m). Mountains traversed by

10920-639: The cause. In 1929, Perkins, who was also a member of the Connecticut Forest and Park Association and its Blue Blazed Trails committee, found Ned Anderson , a farmer in Sherman, Connecticut , who took on the task of mapping and blazing the Connecticut leg of the trail (1929–1933). It ran from Dog Tail Corners in Webatuck, New York , which borders Kent, Connecticut , at Ashley Falls, 50 miles (80 km) through

11060-474: The climate changes significantly, particularly dependent upon elevation. In the south, lowland forests consist mainly of second-growth; nearly the entire trail has been logged at one time or another. There are, however, a few old growth locations along the trail, such as Sages Ravine straddling the Massachusetts-Connecticut border and atop higher peaks along the trail on either side of the same border,

11200-510: The cold climate. Maine also has several alpine regions. In addition to several areas of the Mahoosuc Range, the Baldpates, and Old Blue in southern Maine have alpine characteristics despite elevations below 4,000 feet (1,200 m). Saddleback Mountain and Mount Bigelow , further north, extend only a bit above 4,000 feet (1,200 m), but each has long alpine areas, with no tree growth on

11340-571: The colonial era. The range is the home of a very popular recreational feature, the Appalachian Trail . This is a 2,175-mile (3,500 km) hiking trail that runs all the way from Mount Katahdin in Maine to Springer Mountain in Georgia , passing over or past a large part of the Appalachian range. The International Appalachian Trail is an extension of this hiking trail into the Canadian portion of

11480-457: The continent that are now exposed. The first mountain-building tectonic plate collision that initiated the construction of what are today the Appalachians occurred at least a billion years ago when the pre-North American craton called Laurentia collided with at least one other craton - Amazonia . All the other cratons of the earth also collided at about this time to form the supercontinent Rodinia and were surrounded by one single ocean. (It

11620-641: The continents that were ancestral to North America and Africa collided during the formation of the supercontinent Pangea . Because North America and Africa were once geographically connected, the Appalachians formed part of the same mountain chain as the Little Atlas in Morocco . This mountain range, known as the Central Pangean Mountains , extended into Scotland , before the Mesozoic Era opening of

11760-412: The deciduous needle-leaf conifer, the tamarack , or eastern larch ( Larix laricina ). The dominant northern and high elevation conifer is the red spruce ( Picea rubens ), which grows from near sea level to above 4,000 ft (1,200 m) above sea level (asl) in northern New England and southeastern Canada. It also grows southward along the Appalachian crest to the highest elevations of

11900-529: The driest sites are dominated by chestnut oak, or sometimes by scarlet or northern red oaks. In the northern Appalachians the oaks, except for white and northern red, drop out, while the latter extends farthest north. The oak forests generally lack the diverse small tree, shrub and herb layers of mesic forests. Shrubs are generally ericaceous , and include the evergreen mountain laurel ( Kalmia latifolia ), various species of blueberries ( Vaccinium spp.), black huckleberry ( Gaylussacia baccata ),

12040-414: The entire trail in a single season. The number of thru-hikes per year has increased steadily since 2010, with 715 northbound and 133 southbound thru-hikes reported in 2017. The Appalachian Trail Conservancy estimates there are over 3,000 attempts to traverse the entire trail each year, about 25% of which succeed. Many books, documentaries, and websites are dedicated to the pursuit. Some hike from one end to

12180-684: The first section of the trail, from Bear Mountain west through Harriman State Park to Arden, New York , was opened. MacKaye then called for a two-day Appalachian Trail conference to be held in March 1925 in Washington, D.C. This meeting inspired the formation of the Appalachian Trail Conference (now called the Appalachian Trail Conservancy ) (ATC). Arthur Perkins , a retired judge, and his younger associate Myron Avery took up

12320-425: The folds and faults created many millions of years earlier. Other streams downcut so rapidly that they cut right across the resistant folded rocks of the mountain core, carving canyons across rock layers and geologic structures. The Appalachian Mountains contain major deposits of anthracite coal as well as bituminous coal . In the folded mountains the coal is in metamorphosed form as anthracite , represented by

12460-431: The form spiral-bound notebooks that are kept in containers in shelters all along the trail, and signing in them is not required. These logs give hikers a way to leave day-to-day messages while they are on the trail to document where they have been, where they are going, and who/what they have seen. The logs provide a space for informal writing and can also be used to keep track of people on the trail. Most of all, they provide

12600-837: The highest point in the North ( Mount Washington in New Hampshire) to the highest in the South ( Mount Mitchell in North Carolina). Hiking was an incidental focus of his plan. In 1922, at the suggestion of Major William A. Welch , director of the Palisades Interstate Park Commission , his idea was publicized by Raymond H. Torrey with a story in the New York Evening Post under a full-page banner headline reading "A Great Trail from Maine to Georgia!" On October 7, 1923,

12740-507: The honor system, and recognizes blue-blazed trails or officially required roadwalks as substitutes for the official, white-blazed route during an emergency such as a flood, forest fire, or impending storm on an exposed, high-elevation stretch. As of 2018, more than 19,000 people had reported completing the entire trail. The northbound completion rate of hiking the trail in twelve months or fewer varied from 19% to 27% from 2011 to 2018. The southbound completion rate varied between 27% and 30% during

12880-415: The influx of users escaping home isolation. In 2021, the conservancy suspended issuing hang tags for through-hikers for a period during the continuing pandemic. Trail hikers who attempt to complete the entire trail in a single season are called " thru-hikers "; those who traverse the trail during a series of separate trips are known as "section-hikers". Rugged terrain, weather extremes, illness, injury, and

13020-480: The land mass that is now New England and southwestward to Pennsylvania. The Taconic Orogeny was the second of four mountain building plate collisions that contributed to the formation of the Appalachians, culminating in the collision of North America and Africa (see Alleghanian orogeny ). The third mountain-building event was the Acadian orogeny which occurred between 375 and 359 million years ago. The Acadian orogeny

13160-469: The latter. However, balsam fir also does well in soils with a pH as high as 6. Eastern or Canada hemlock ( Tsuga canadensis ) is another important evergreen needle-leaf conifer that grows along the Appalachian chain from north to south but is confined to lower elevations than red spruce and the firs. It generally occupies richer and less acidic soils than the spruce and firs and is characteristic of deep, shaded and moist mountain valleys and coves . It

13300-457: The lungs. The affected hiker recovered and hiked the trail the following year. The section of the trail that runs through the Mid-Atlantic and New England states has a very high population of deer ticks carrying Lyme and other tick-borne diseases, and corresponds to the highest density of reported Lyme disease in the country. The weather is a major consideration for hikers. Hiking season of

13440-528: The microclimates that best suited them. The flora of the Appalachians are diverse and vary primarily in response to geology, latitude, elevation and moisture availability. Geobotanically, they constitute a floristic province of the North American Atlantic Region . The Appalachians consist primarily of deciduous broad-leaf trees and evergreen needle-leaf conifers, but also contain the evergreen broad-leaf American holly ( Ilex opaca ), and

13580-652: The more notable peaks in West Virginia. The Blue Ridge Mountains , rising in southern Pennsylvania and there known as South Mountain , attain elevations of about 2,000 ft (600 m) in Pennsylvania. South Mountain achieves its highest point just below the Mason-Dixon line in Maryland at Quirauk Mountain 2,145 ft (654 m) and then diminishes in height southward to the Potomac River . Once in Virginia ,

13720-745: The mountainous belt just north of the New River in Virginia. South of the New River, rivers head into the Blue Ridge, cross the higher Unakas, receive important tributaries from the Great Valley, and traversing the Cumberland Plateau in spreading gorges ( water gaps ), escape by way of the Cumberland River and the Tennessee River rivers to the Ohio River and the Mississippi River, and thence to

13860-538: The mountainous belt, and thus the main lines of drainage run from north to south, exemplified by the Hudson River . However, the valley through which the Hudson River flows was cut by the gigantic glaciers of the ice ages —the same glaciers that deposited their terminal moraines in southern New York and formed the east–west Long Island . The Appalachian region is generally considered the geographical divide between

14000-567: The new trail cleared and blazed, by six Boy Scouts from New York City and their guides. The thru-hike was much later recorded and accepted by the Appalachian Long Distance Hikers Association . In 1938, the trail sustained major damage from a hurricane that went through the New England area. This was soon before the start of World War II, and many of the people working on the trail were called to active duty. In 1948, Earl Shaffer of York, Pennsylvania , brought

14140-531: The northwest coastline of Newfoundland. The dissected plateau area, while not actually made up of geological mountains, is popularly called "mountains", especially in eastern Kentucky and West Virginia, and while the ridges are not high, the terrain is extremely rugged. In Ohio and New York, some of the plateau has been glaciated , which has rounded off the sharp ridges and filled the valleys to some extent. The glaciated regions are usually referred to as hill country rather than mountains. The Appalachian belt includes

14280-510: The northwest corner of the state, up to Bear Mountain at the Massachusetts state line. A portion of the Connecticut trail has since been rerouted (1979–1983) to be more scenic, adhering less to highways and more to wilderness, and includes the Ned K. Anderson Memorial Bridge. Anderson's efforts helped spark renewed interest in the trail, and Avery, who led the project after Perkins's death in 1932,

14420-424: The oceans, but there were no plants or animals on land. Then, during the middle Ordovician Period about 500 to 470 million years ago, the motion of the crustal plates changed, and the continents began to move back toward each other. The once-quiet Appalachian passive margin changed to a very active plate boundary when a neighboring Iapetus oceanic plate containing a volcanic arc collided with and began sinking beneath

14560-467: The organization's "A.T. Community" program, having become recognized for providing food, supplies and accommodations for passers-through. In the areas of the trail closer to trail towns, many hikers have experienced what is sometimes called "trail magic", or assistance from strangers through kind actions, gifts, and other forms of encouragement. Trail magic is sometimes done anonymously. In other instances, persons have provided food and cooked for hikers at

14700-407: The original trail often climbed straight up and down mountains, creating rough hiking conditions and a treadway prone to severe erosion. The ATC's trail crews and volunteer trail-maintaining clubs have relocated or rehabilitated miles of trail since then. In 1936, a 121-day Maine to Georgia veteran's group funded and supported thru-hike was reported to have been completed, with all but three miles of

14840-744: The other, then turn around and thru-hike the other way, a "yo-yo". Affiliated trail sections extend from either end from the north as the International Appalachian Trail into Canada and beyond, and from the south as the Eastern Continental Trail into the Southeastern states of Alabama and Florida . The Appalachian Trail, the Continental Divide Trail , and the Pacific Crest Trail informally constitute

14980-704: The plateaus sloping southward to the Atlantic Ocean in New England , and southeastward to the border of the coastal plain through the central and southern Atlantic states; and on the northwest, the Allegheny and Cumberland plateaus declining toward the Great Lakes and the interior plains. A remarkable feature of the belt is the longitudinal chain of broad valleys, including the Great Appalachian Valley , which in

15120-588: The region level. The lowest level of classification is "section". The Appalachian Uplands are one of the seven physiographic divisions in Canada . Canada's GSC does not use the same classification system as the USGS below the division level. The agency does break the divisions of the Appalachian Uplands into 13 subsections that are in four different political provinces of Canada. While the Appalachian Highlands and Appalachian Uplands are generally continuous across

15260-454: The residents of the regions regarding the correct pronunciation. Elsewhere, a commonly accepted pronunciation for the adjective Appalachian is / ˌ æ p ə ˈ l æ tʃ i ə n / , with the last two syllables "-ian" pronounced as in the word "Romanian". Perhaps partly because the range runs through large portions of both the United States and Canada, and partly because the range was formed over numerous geologic time periods, one of which

15400-482: The result of volcanic activity that occurred around this time. Evidence of subsurface activity, dikes and sills intruding into the overlying rock, is present in the Blue Ridge as well. For instance, mafic rocks have been found along the Fries Fault in the central Blue Ridge area of Montgomery County, VA. The Iapetus continued to expand and during that time bacteria, algae, and many species of invertebrates flourished in

15540-466: The rocks to be folded and faulted, creating the first mountains in the region. Many of the rocks and minerals that were formed during that event can currently be seen at the surface of the present Appalachian range. Around 480 million years ago, geologic processes began that led to three distinct orogenic eras that created much of the surface structure seen in today's Appalachians. During this period, mountains once reached elevations similar to those of

15680-706: The same side of the Great Valley, south of the Potomac, are the Pinnacle 3,007 feet (917 m) and Pidgeon Roost 3,400 ft (1,000 m). In West Virginia, more than 150 peaks rise above 4,000 ft (1,200 m), including Spruce Knob 4,863 ft (1,482 m), the highest point in the Allegheny Mountains . A number of other points in the state rise above 4,800 ft (1,500 m). Cheat Mountain ( Snowshoe Mountain ) at Thorny Flat 4,848 ft (1,478 m) and Bald Knob 4,842 ft (1,476 m) are among

15820-409: The same trend as the system itself. None of the summits reaches the region of perpetual snow. In Pennsylvania , there are over sixty summits that rise over 2,500 ft (800 m); the summits of Mount Davis and Blue Knob rise over 3,000 ft (900 m). In Maryland, Eagle Rock and Dans Mountain are conspicuous points reaching 3,162 and 2,882 ft (964 and 878 m) respectively. On

15960-453: The south would be far from the subalpine cutoff. This is especially low because Greylock is exposed to prevailing westerly winds, as the summits along its ridgeline rise about 200 to 650 feet (61 to 198 m) higher than any other peak in Massachusetts. Farther north, several peaks in Vermont reach into the subalpine zone, the bottom of which steadily descends as one proceeds northward, so that by

16100-481: The southerly sections divides the mountain system into two unequal portions, but in the northernmost lies west of all the ranges possessing typical Appalachian features, and separates them from the Adirondack group. The mountain system has no axis of dominating altitudes, but in every portion, the summits rise to rather uniform heights, and, especially in the central section, the various ridges and intermontane valleys have

16240-416: The southern Appalachians, as in North Carolina and Tennessee . In the central Appalachians it is usually confined above 3,000 ft (900 m) asl, except for a few cold valleys in which it reaches lower elevations. In the southern Appalachians, it is restricted to higher elevations. Another species is the black spruce ( Picea mariana ), which extends farthest north of any conifer in North America,

16380-413: The southern and central Appalachians consist largely of black , northern red , white , chestnut and scarlet oaks ( Quercus velutina, Q. rubra, Q. alba, Q. prinus and Q. coccinea ) and hickories, such as the pignut ( Carya glabra ) in particular. The richest forests, which grade into mesic types, usually in coves and on gentle slopes, have predominantly white and northern red oaks, while

16520-511: The southern and central Appalachians at low and intermediate elevations. In the northern Appalachians and at higher elevations of the central and southern Appalachians these diverse mesic forests give way to less diverse northern hardwood forests with canopies dominated only by American beech, sugar maple, American basswood ( Tilia americana ) and yellow birch and with far fewer species of shrubs and herbs. Drier and rockier uplands and ridges are occupied by oak–chestnut forests dominated by

16660-410: The southern regions of the Appalachians, the word is pronounced / ˌ æ p ə ˈ l æ tʃ ɪ n z / , with the third syllable sounding like "latch". In northern parts of the mountain range, it is pronounced / ˌ æ p ə ˈ l eɪ tʃ ɪ n z / or / ˌ æ p ə ˈ l eɪ ʃ ɪ n z / ; the third syllable is like "lay", and the fourth "chins" or "shins". There is often great debate between

16800-535: The southernmost spur of the Blue Ridge Mountains. Sources written prior to the recognition of the concept of physiographic regions divided the Appalachian Mountains into three major sections: Plate tectonics over the period dating back at least 1 billion years led to geological creation of the land that is now the Appalachian Mountain range. The continental movement led to collisions that built mountains and they later pulled apart creating oceans over parts of

16940-530: The state ranges from around 2,500 feet (760 m) in the Mahoosuc Range to below 1,000 feet (300 m) in parts of the Hundred-Mile Wilderness , where nearly every area higher than 1,000 feet (300 m) is evergreen forest. These forests include more species of evergreen, as well. In addition to the white pine , spruce , and hemlock prevalent further south, Maine has many cedar trees along

17080-571: The summer months. The Fontana Dam Shelter in North Carolina is more commonly referred to as the Fontana Hilton because of amenities (e.g. flushable toilets) and its proximity to an all-you-can-eat buffet and post office. Several AMC huts have an extended self-service season during the fall, with two extending self-service seasons through the winter and spring. The Potomac Appalachian Trail Club maintains trail cabins, shelters, and huts throughout

17220-462: The summit and unobstructed views on clear days. From Mount Bigelow, the trail extends for 150 miles (240 km) with only a small area of alpine growth around 3,500 feet (1,100 m) on the summit of White Cap Mountain . Mount Katahdin, the second-largest alpine environment in the eastern United States, has several square miles of alpine area on the flat "table land" summit as well as the cliffs and aretes leading up to it. Treeline on Mount Katahdin

17360-524: The term Appalachian Highlands and Canada uses the term Appalachian Uplands ; the Appalachian Mountains are not synonymous with the Appalachian Plateau , which is one of the provinces of the Appalachian Highlands. The Appalachian range runs from the Island of Newfoundland in Canada, 2,050 mi (3,300 km) southwestward to Central Alabama in the United States; south of Newfoundland, it crosses

17500-450: The time and effort required make thru-hiking difficult to accomplish. As of 2017, the Appalachian Trail Conservancy estimated that 3,839 hikers set out from Springer Mountain, northbound, 497 from Mount Katahdin, southbound, and reported 1,186 completions of hiking the entire trail, which includes those by both section and through hikers. Most thru-hikers walk northward from Georgia to Maine, and generally start out in early spring and follow

17640-479: The trail also used metal diamond markers with the AT logo, few of which survive. Most hikers carry a lightweight tent, tent hammock or tarp. The trail has more than 250 shelters and campsites available for hikers. The shelters, sometimes called lean-tos (in Maine, Massachusetts, and Connecticut), huts (in Shenandoah National Park), or Adirondack shelters, are generally open, three-walled structures with

17780-424: The trail from development, thanks to efforts of politicians and officials. Wisconsin senator Gaylord Nelson offered legislation to protect the route. The National Trails System Act of 1968 designated the Pacific Crest Trail and Appalachian Trail as the first national scenic trails and paved the way for a series of such trails within the national park and national forest systems. Trail volunteers worked with

17920-478: The trail generally starts in mid-to-late spring, when conditions are much more favorable in the South. However, this time may also be characterized by extreme heat, sometimes in excess of 100 °F (38 °C). Farther north and at higher elevations, the weather can be characterized by low temperatures, strong winds, hail or snow storms and reduced visibility. Prolonged rain, though not typically life-threatening, can undermine stamina and ruin supplies. In March 2015,

18060-660: The trail in 1937: Roan Mountain , North Carolina and Tennessee; the Mount Rogers high country, including Grayson Highlands , Virginia; the Pochuck Creek swamp, New Jersey; Nuclear Lake, New York; Thundering Falls, Vermont; and Saddleback Mountain , Maine. Except for places where the Civilian Conservation Corps was brought in (mostly in Shenandoah National Park , the Great Smoky Mountains , and Maine),

18200-496: The trail in Shenandoah National Park. The primary suspect was later discovered harassing a female cyclist in the vicinity, but charges against him were dropped and the case remained unsolved until 2024. In May 2019, Oklahoman Ronald S. Sanchez Jr., 43 years old, was murdered at a campsite near Mount Rogers National Recreation Area in western Virginia Jefferson National Forest. A female hiker who has not been identified

18340-417: The trail through Pennsylvania are so rocky that hikers call the region "Rocksylvania". These small rocks, which are the result of erosion that has worn away the dirt along the trails, can be tough to walk on for extended periods of time without proper hard-soled shoes. In Maine , the trail extends into even harsher environments, and subalpine and alpine growth descends to lower elevations. Alpine growth in

18480-464: The trail, making him the oldest person to claim a completed thru-hike. The first woman to walk the trail in a single season was Peace Pilgrim in 1952, while the first solo woman to complete the hike was 67-year-old Emma Gatewood , who did it northbound in 1955, taking 146 days. She repeated the achievement two years later, and again in 1963, at age 75. In the 1960s, the ATC made progress toward protecting

18620-445: The trail. Many animals live around the trail, with bears, snakes, and wild boars posing the greatest threat to human safety. Several rodent- and bug-borne illnesses are also a potential hazard. In scattered instances, foxes, raccoons , and other small animals may bite hikers, posing risk of rabies and other diseases. There has been one reported case (in 1993) of hantavirus (HPS), a rare but dangerous rodent-borne disease affecting

18760-409: The trail. Near the northern terminus, there are even some tamarack (larch), a coniferous, pine-needled deciduous tree, which provides displays of yellow in the late fall after the birches and maples have gone bare. The hemlocks in Maine are also notable, as the woolly adelgid , which has ravaged populations further south, has not come into the state yet, and may be unable to make it so far north due to

18900-663: The two main crests. Major subranges of the Eastern Front include the Black Mountains , Great Craggy Mountains , and Great Balsam Mountains , and its chief summits include Grandfather Mountain 5,964 ft (1,818 m) near the Tennessee-North Carolina border, Mount Mitchell 6,684 ft (2,037 m) in the Blacks, and Black Balsam Knob 6,214 ft (1,894 m) and Cold Mountain 6,030 ft (1,840 m) in

19040-424: The warm weather as it moves north. These "north-bounders" are also called NOBO (NOrthBOund) or GAME (Georgia(GA)-to-Maine(ME)), while those heading in the opposite direction are termed "south-bounders" (also SOBO or MEGA). A thru-hike generally requires five to seven months, although some have done it in three months, and several trail runners have completed the trail in less time. Trail runners typically tackle

19180-405: Was able to bring other states on board. Upon taking over the ATC, Avery adopted the goal to build a simple hiking trail. He and MacKaye clashed over the ATC's response to the construction of a road that overlapped part within Shenandoah National Park; MacKaye left the organization, while Avery was willing to reroute the trail. Avery served as Chair of the ATC from 1932 to 1952, the year he died. He

19320-464: Was also injured by an assailant there. James L. Jordan, 30, of West Yarmouth, Massachusetts was found not guilty of the crimes by reason of insanity. Human error can lead to casualties as well. In July 2013, 66-year-old lone hiker Geraldine Largay disappeared on the trail in Maine. Largay became lost and survived 26 days before dying. Her remains were found two years later in October 2015. In October 2015,

19460-639: Was caused by a series of collisions of pieces of crust from the Avalonia Terrane, sections broken off from continent of Gondwana , with the North American Plate. The collision initiating this orogeny resulted in the closing of the southern Iapetus Ocean and the formation of a high mountain belt. After the Acadian collision took place, Gondwana began to retreat from Laurentia with the newly accreted Avalonian terranes left behind. As Gondwana moved away,

19600-407: Was the first to walk the trail end-to-end, though not as a thru-hike, in 1936. In August 1937, the trail was completed to Sugarloaf Mountain in Maine, and the ATC shifted its focus toward protecting the trail lands and mapping the trail for hikers. In 1977, the Appalachian Trail Conference honored Paul M. Fink as "the guiding influence" in establishing the Trail in Tennessee and North Carolina in
