The Appalachian National Scenic Trail, generally known as the Appalachian Trail or simply The A.T., is a marked hiking trail in the eastern United States, extending between Springer Mountain in Georgia and Mount Katahdin in Maine. It is more than 2000 miles (3,200 km) long. The path is maintained by thirtyone trail clubs and multiple partnerships. The Appalachian Trail is famous for its many hikers, many of whom attempt to hike it in its entirety, often non-stop. Many books, memoirs, Web sites and other organizations are dedicated to this pursuit.
Along the way, the trail passes through the states of Georgia, North Carolina, Tennessee, Virginia, West Virginia, Maryland, Pennsylvania, New Jersey, New York, Connecticut, Massachusetts, Vermont , New Hampshire and Maine.
The trail was conceived by Benton MacKaye, a forester who wrote his original plan shortly after the death of his wife in 1921. MacKaye's Utopian idea detailed a grand trail that would connect a series of farms and wilderness work/study camps for city-dwellers. 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!" The idea was quickly adopted by the new Palisades Interstate Park Trail Conference as their main project.
Bear Mountain Bridge On October 7, 1923, 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 resulted in the formation of the Appalachian Trail Conference organization, though little progress was made on the trail for several years.
At the end of the 1920s and beginning of the 1930s, a retired judge named Arthur Perkins and his younger associate Myron Avery took up the cause. Avery, who soon took over the ATC, adopted the more practical goal of building a simple hiking trail. He and MacKaye clashed over the ATC's response to a major commercial development along the trail's path; MacKaye left the organization, while Avery was willing to simply reroute the trail. Avery became 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. From 1938 to the end of World War II, the trail suffered a series of natural and man-made setbacks. At the end of the war, the damage to the trail was repaired.
In 1948, Earl Shaffer of York, Pennsylvania, brought a great deal of attention to the project by completing the first documented thru-hike. (In 1994, a story appeared in the Appalachian Trailway News describing a 121-day Maine to Georgia thru-hike in 1936 by six Boy Scouts from the Bronx. The story has been accepted by some individual members of ALDHA, though a great deal of doubt has also been expressed; this earlier thru-hike has never been verified or accepted by any responsible hiking organization or group; therefore, Shaffer's 1948 journey is still universally recognized as the first A.T. thru-hike. Earl also completed a 50th. Anniversary hike in 1998 and was a guest of Uncle Johnny's Nolichucky Hostel in Erwin, Tennessee.
In the 1960s, the ATC made progress toward protecting the trail from development, thanks to many sympathetic politicians and officials. The National Trails System Act of 1968 paved the way for a series of National Scenic Trails within the National Park and National Forest systems. Trail volunteers worked with the National Park Service to map a permanent route for the trail, and by 1971 a permanent route had been marked (though minor changes continue to this day). By the close of the 20th century, the Park Service had completed the purchase of all but a few miles of the trail's span.
The Appalachian Trail should not be confused with the International Appalachian Trail, a 675- mile (1,100 km) extension, running north from Maine into New Brunswick and Quebec. It is actually a separate trail, not an official extension of the Appalachian Trail. An extension of the International Appalachian Trail, to Newfoundland, is still under construction. Flora and fauna
The Appalachian Trail is home to literally thousands of species of plant and animal, of air, land and sea, including 2,000 distinct rare, threatened, endangered, and sensitive plant and animal species.
The American black bear is the largest omnivore that would be encountered on the trail, and it inhabits all parts. However, bear sightings are rare, and hiker incidents still rarer, as black bears typically avoid humans and can usually be frightened away by making loud noise. Though they do not truly hibernate, they spend a large portion of the winter asleep. They are omnivorous, eating grass, roots, berries and small- to medium-sized mammals. Venomous snakes, including the Eastern timber rattlesnake and copperhead. will only strike when disturbed. Both snakes are generally found in drier, rockier sections of the trail; the copperhead's range extends north to around the New Jersey-New York state line, while rattlesnakes are commonly found along the trail in Connecticut and have been reported, although rarely, as far north as New Hampshire. Other large fauna include deer (which, while harmless, do aid in the spread of Lyme disease), elk, reintroduced in the Smoky Mountains, and moose, which live as far south as Massachusetts but are mainly seen in Maine. The most persistent pests along the trail are mice and bugs. Mice inhabit shelters and are a greater threat to hiker food than bears. The mice mostly occupy shelters where poor food prep/care has been practiced and so the mice have grown up on human food and do not lose the taste. The bugs are a persistent hazard, but are particularly bad in the northern stretches of the trail. Connecticut, Massachusetts, and New York have notoriously bad mosquitoes, but the worst section of the trail for bugs is in the lowlands of Maine. The northern hardwood and boreal forest of Maine is perfect for mosquitoes and tiny, pesky black flies to breed. Numerous lakes, rivers, and streams provide the perfect habitat for biting insects to breed and hatch, especially in late spring and early summer. Hiking Maine before the black flies begin to die off in July is something of a blood-letting for the hiker, while the most pleasant time of the year may well be after frosts have killed the bugs in late September or October. In the South, mosquitoes, no-see-em and other biting flies are less of a nuisance because there are fewer mountain lakes and ponds, plus the lack of seasonal changes in the South keeps the onslaught of these biting insects down, unlike the spring season further north. The continental glaciation that carved so many lakes in the northeast stopped near the Delaware Water Gap, leaving the southern mountains with fewer holes to be filled by rain.
Plant life along the trail is varied. 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 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. Further north, tulip trees are gradually replaced by maples and birches. Oaks begin to disappear in Massachusetts. By Vermont, the lowland forest is made up of maples, birch and beech, which provide spectacular foliage displays for hikers 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. At higher elevations, the makeup of the forest is dramatically different. There is a drastic change between the lowland and subalpine, evergreen forest, as well as another, higher break, at treeline, above which only hardy alpine plants grow. The sub-alpine region 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. These include the Great Smoky Mountains, where sub-alpine environments only begin around 6000 feet in elevation, the Unaka and Roan Mountain Ranges on the North Carolina-Tennessee border, where sub- alpine growth descends below 6000 feet, and Mount Rogers and the Grayson Highlands in Virginia, where there is some alpine growth above 5000 feet. Some high mountains in the south are also balds. While not necessarily above treeline, these mountains have only grassy summits for whatever reason, perhaps due to fires or grazing in recent centuries, or perhaps due to thin, sandy soils. Several balds are sprouting trees, and on some, the National Forest service actually mows the grasses periodically in order to keep the bald open.
No sub-alpine regions exist between Mount Rogers in Virginia and Mount Greylock in Massachusetts, mainly because the trail stays below 3000 feet from Shenandoah National Park in Virginia to Mount Greylock. Mount Greylock, however, has a large subalpine region, the only such forest in Massachusetts, extending down to 3000 feet, which in the south would be far from the sub-alpine cutoff. This is especially low because Greylock is exposed to prevailing westerly winds, as its summit rises 1000 feet higher than any other peak in Massachusetts.
Further north, several peaks in Vermont reach into the sub-alpine zone, the bottom of which steadily descends, so that by the White Mountains in New Hampshire, it often occurs well below 3000 feet. At Mount Moosilauke, which reaches to 4802 feet, the first alpine environment on the trail is reached, where only thin, sporadic flora is 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, thus giving the appearance of flags (they are often called "flag trees"). This region resembles lowland land cover hundreds of miles north in Canada, and 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 4200 and 4800 feet. Mountains traversed by the AT above treeline include Mount Moosilauke, several miles along the Franconia Range, and the Presidential Range. In the Presidentials, the trail climbs as high as 6288 feet (1917 meters) on Mount Washington and spends about 13 miles continuously above treeline, in the largest alpine environment in the United States east of the Rocky Mountains. In Maine, the trail extends in to even harsher environments, and sub-alpine and alpine growth descends to lower elevations. Alpine growth in the state ranges from around 2500 feet in the Mahoosuc Range to below 1000 feet in parts of the 100-Mile Wilderness, where nearly every area higher than 1000 feet 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 the trail. Near the northern terminus, there are even some tamarack, 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 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 4000 feet. Saddleback Mountain and Mount Bigelow, further north, each only extend a bit above 4000 feet, but have long alpine areas, with no tree growth on the summits and unobstructed views on clear days. From Mount Bigelow, the trail extends for 150 miles with only a small area of alpine growth around 3500 feet 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 Katahdin is only around 3500 feet. This elevation in Massachusetts would barely be a sub-alpine region, and, south of Virginia, consists of lowland forest. This illustrates the drastic change in climate over 2000 miles.
Hiking the trail
As the Appalachian Trail was explicitly designed to be hiked, it includes resources to facilitate hikers. Some are common to trails throughout North America, while some are unique to the Appalachian Trail. The trail is much more frequently hiked south to north (i.e. Georgia to Maine) than vice versa; though it is occasionally hiked north to south. Hikers typically begin in March or April and finish in late summer or early to late fall of that particular year. Many hikers will break down the mileage into halves or thirds, so that they can have optimal weather (which typically occurs between May and September) to do their hike.
Throughout the length of the trail there are over 200 shelters and camp sites available for hikers. The shelters, sometimes called lean-tos (in Maine) or huts (in New Hampshire), are generally open, three-walled structures with a wooden floor. Some shelters are much more complex in structure; however, for the most part, function is emphasized over form in their construction. Shelters are spaced less than a day's hike apart, most often near a water source and with a privy. They generally have spaces for tent sites in the vicinity, as well. It is always advisable to carry a tent when overnighting on the trail, since shelters may be filled to capacity, especially early in the season, and where they occur near parks. These shelters are generally well-maintained by local volunteers and kept in good condition. In spite of this, mice and other rodents often make their homes inside or nearby. 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) for hikers to hang their food bags on. In hiker lingo, these are sometimes called "mouse trapezes." While they usually prevent mice from reaching hung food, they are by no means impervious. For outdoor lodgers, another option is to hang one's food from a tree branch or between two trees, using the standard bear bagging method, which is highly recommended in bear country.
In addition to official AT shelters, many persons offer their homes, places of business, or inns to accommodate AT hikers. One example is the Little Lyford Pond camps maintained by the Appalachian Mountain Club. These historic camps exist 13 miles from Greenville, Maine, near Gulf Hagas. Inns are more common in sections of the trail that coincide with national parks, most notably Virginia's Shenandoah National Park.
An information house in Boiling Springs, PennsylvaniaThe trail crosses many roads, thus providing ample opportunity for hikers to hitchhike into town for food and other supplies. Many trail towns are accustomed to hikers passing through, and thus many have hostels and hiker-oriented accommodations. Some of the most well-known trail towns are Monson, Maine; Harpers Ferry, West Virginia; Damascus, Virginia; Hot Springs, North Carolina; Erwin, Tennessee; Duncannon, Pennsylvania; Port Clinton, Pennsylvania; and Hanover, New Hampshire. 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. For example, a person may leave water, food, or other provisions for hikers to find later. In other instances, persons have provided food and cooked for hikers at a campsite. Trail magic is ultimately a form of goodwill.
The Appalachian Trail is relatively safe. Most injuries or incidents are consistent with comparable outdoor activities, like rock climbing. However, there are a variety of hazards on the trail that have caused persons to be become extremely lost, injure themselves, and even lose their lives. Most of these hazards are related to weather conditions, human error, plants, animals, diseases, and fellow humans encountered along the trail. Adequate preparation can usually reduce, if not eliminate, many of these hazards. As mentioned earlier, there are many animals that live around the trail, with bears, snakes, and wild boars providing the most threat. However, the proper handling and storage of food in bear bags, and paying attention to where one sits or steps can greatly reduce the risk of dangerous encounters with these animals.
Several rodent- and bug-borne illnesses pose a threat on the trail. Ticks, in particular, are carriers for Lyme disease, ehrlichiosis and other diseases, and are in higher abundance in northern states. Being thoroughly covered and wearing DEET can greatly reduce the chances of getting infected. In other scattered instances, foxes, raccoons, and other small animals may bite hikers, and such bites always pose the risk of rabies. There has been exactly one reported case (in 1993) of hantavirus (HPS), a rare but dangerous rodent-borne disease affecting the lungs. The afflicted hiker recovered and hiked the trail the following year.
Poison Ivy Plant life can create its own brand of problems. Poison ivy is common the length of the trail, and more plentiful in the South. Avoidance is the best line of defense. Local flare-upscan be treated with calamine lotion or Solarcaine.
Since the hiking season of the trail generally starts in mid to late spring, hiking conditions during this time are much more favorable in the South. However, this time may also be characterized by extreme heat, sometimes in excess of 100°F. Under such conditions, sufficient hydration is imperative. Also, light clothing and sunscreens are a must at high elevations and areas without foliage, even in relatively cool weather. Further north and at higher elevations, the weather can be intensely cold, characterized by extremely low temperatures, strong winds, hail or snow storms and critically reduced visibility. Lack of adequate shelter, appropriate clothing and reliable maps can lead to hypothermia or worse. Also, prolonged rain, though not typically life-threatening, can undermine a hiker's stamina and ruin a stash of supplies. Additionally, thunderstorms can increase the distant chance of getting hit by lightning, so typical electrical storm precautions should be followed. Hikers often combat precipitation by carrying a pack, tent and rainwear. Along the trail, weather can be unpredictable, so long-term, overnight hikers in particular must be prepared for the worst if they are to be successful.
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 and cold weather during the spring and fall make thru-hiking difficult. Only about 20% of those who make the attempt report to the Appalachian Trail Conservancy that they have done so, and it is widely acknowledged that many or even most of these have skipped portions of the Trail. Completion 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 almost always tackle the AT with automobile support teams, generally without backpacks, and frequently without camping in the woods. (The Appalachian Trail Conservancy generally disapproves of this sort of activity as well as other "stunt" or publicity-seeking hikes; the ATC feels that such activities are inappropriate and are a degradation of the Trail's purpose).
Thru-hikers are classified into many informal groups. "Purists" are hikers who stick to the official AT trail except for side trips to shelters and camp sites. "Blue Blazers" cut miles from the full route by taking side trails marked by blue blazes. The generally pejorative name "Yellow Blazers," a reference to yellow road stripes, is given to those who hitchhike to move down the trail.
Most thru-hikers walk northward from Georgia to Maine, and generally start out in early spring and follow the warm weather as it moves north. These "north-bounders" are also called NOBO or GAME, while those heading in the opposite direction are termed "south- bounders".
Part of hiker subculture includes making colorful entries in logbooks at trail shelters, signed using 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.
Recognizing blue-blazed trails or officially required roadwalks as viable substitutes for the official, white-blazed route in the event of an emergency, such as a flood, a forest fire, or an impending storm on an exposed high-elevation stretch. Operates on the honor system.
Most of the trail is also open to local use. Although there are some rules and regulations that favor thru-hikers, some believe that the emphasis on hiking the entire length of the trail is misplaced.
The trail is currently protected along more than 99% of its course by federal or state ownership of the land or by right-of-way. Annually, more than 4,000 volunteers contribute over 175,000 hours of effort on the Appalachian Trail, an effort coordinated largely by the Appalachian Trail Conservancy (ATC) organization.
In the course of its journey, the trail follows the ridgeline of the Appalachian Mountains, crossing many of its highest peaks, and running, with only a few exceptions, almost continuously through wilderness.
A hiker signs the register on Springer Mountain,Georgia has 75 miles (120 km) of the trail, including the southern terminus at Springer Mountain at an elevation of 3,280 feet (992 m). At 4,461 feet (1360 m), Blood Mountain is the highest point on the trail in Georgia. The AT and approach trail are managed and maintained by the Georgia Appalachian Trail Club. See also: Georgia Peaks on the Appalachian Trail.
North Carolina has 88 miles (142 km) of the trail, not including more than 200 miles (325 km) along the Tennessee Border. Altitude ranges from 1,725 to 5,498 feet (525 m to 1676 m). Tennessee has 293 miles of the trail, including more than 200 miles (325 km) along or near the North Carolina Border. The section that runs just below the summit of Clingmans Dome in Great Smoky Mountains National Park is the highest point on the trail at 6,625 feet (2019 m).
The Pocosin trail in Shenandoah National Park Virginia has 550 miles (885 km) of the trail, including about 20 miles (32 km) along the West Virginia border. Some consider this to be the wettest, most challenging part of the hike for northbound hikers because of the spring thaw. On average, it rains 20 out of 30 days during the spring. Substantial portions closely parallel the Skyline Drive and the Blue Ridge Parkway in Shenandoah National Park. Parts of the trail near the Blue Ridge Parkway are often considered the best for beginner hikers. West Virginia has 4 miles (6 km) of the trail, not including about 20 miles (32 km) along the Virginia border. Here the trail passes through the town of Harpers Ferry, headquarters of the Appalachian Trail Conservancy. Harpers Ferry is considered the "psychological midpoint" of the AT.
Maryland has 41 miles (66 km) of the trail, with elevations ranging from 230 to 1,880 feet (70- 570 m). This section, great for three- or four-day trips, is easy by AT standards, and is a good place for hikers to find out if they are ready for more rugged parts of the trail. Hikers are required to stay at designated shelters and campsites. Pennsylvania has 229 miles (369 km) of the trail. The trail extends from the Pennsylvania - Maryland line at Pen Mar, a tiny town straddling the state line, to the Delaware Water Gap, at the Pennsylvania - New Jersey border. The Susquehanna River is generally considered the dividing line between the northern and southern sections of the Pennsylvania AT. The AT passes through St. Anthony's Wilderness, which is the second largest roadless area in Pennsylvania and home to several coal mining ghost towns, such as Yellow Springs and Rausch Gap.
Sunfish Pond on the Appalachian trail in New Jersey. New Jersey is home to 72 miles (116 km) of the trail. The trail enters New Jersey from the south on a pedestrian walkway along the Interstate 80 bridge over the Delaware River, ascends from the Delaware Water Gap to the top of Kittatinny Ridge in Worthington State Forest, passes Sunfish Pond (right), continues through Stokes State Forest and eventually reaches High Point State Park, highest peak in New Jersey (a side trail is required to reach the actual peak). It then turns in a southeastern direction along the New York border for about 30 miles (48 km), passing over long sections of boardwalk bridges over marshy land, then entering Wawayanda State Park and then the Abraham Hewitt State Forest just before entering New York near Greenwood Lake.
Black bear activity along the trail in New Jersey increased rapidly starting in 2001. Hence, metal bear-proof trash boxes are in place at all New Jersey shelters. Island Pond, Harriman State ParkNew York's 88 miles (142 km) of trail contain very little elevation change compared to other states. From south to north, the trail summits many small mountains under 1,400 feet (430 m) in elevation, its highest point in New York being Prospect Rock at 1,433 feet (438 m), and only 3,000 feet (800 m) from the border with New Jersey. The trail continues north, climbing near Fitzgerald Falls, passing through Sterling Forest, and then entering Harriman State Park and Bear Mountain State Park. It crosses the Hudson River on the Bear Mountain Bridge, the lowest point on the entire Appalachian Trail at 124 feet (38 m). It then passes through Fahnestock State Park, and continues northeast until it enters Connecticut via the Pawling Nature Reserve. The section of the trail that passes through Harriman and Bear Mountain State Parks is the oldest section of the trail, completed in 1923.
The 52 miles (84 km) of trail in Connecticut, lie almost entirely along the ridges to the west above the Housatonic River valley.
The state line is also the western boundary of a 480-acre (190 ha) Connecticut reservation inhabited by 11 Schaghticoke Indians. Inside it, the AT roughly parallels its northern boundary, crossing back outside it after 2,000 feet (640 m). Mount Greylock in Massachusetts.Massachusetts has 90 miles (145 km) of trail. The entire section of trail is in western Massachusetts' Berkshire County. It summits the highest peak in the Southern Berkshires, Mount Everett (2,602 ft., 793 m), then descends to the Housatonic River Valley and skirts the town of Great Barrington. The trail passes through the towns of Dalton and Cheshire, and summits the highest point in the state at 3,491 feet (1,064 m), Mount Greylock. It then quickly descends to the valley within 2 miles (3 km) of North Adams and Williamstown, before ascending again to the Vermont state line. The trail throughout Massachusetts is maintained by the Berkshire Chapter of the Appalachian Mountain Club.
Vermont has 150 miles (241 km) of the trail. Upon entering Vermont, the trail coincides with the southernmost sections of the generally north/south-oriented Long Trail (which is subject to a request by its maintainers to protect it in its most vulnerable part of the year by forgoing spring hiking). It follows the ridge of the southern Green Mountains, summitting such notable peaks as Stratton Mountain, Glastenbury Mountain and Killington Peak. After parting ways with the Long Trail at Maine Junction, the AT turns in a more eastward direction, crossing the White River, passing through Norwich, and entering Hanover, New Hampshire, as it crosses the Connecticut River. The Green Mountain Club maintains the AT from the Massachusetts state border to Route12. The Dartmouth Outing Club maintains the trail from Route 12 to the New Hampshire state line.
New Hampshire has 161 miles of the trail. The New Hampshire AT is nearly all within the White Mountain National Forest. For northbound thru-hikers, it is the beginning of the main challenges that go beyond enduring distance and time: in New Hampshire and Maine, rough or steep ground are more frequent and alpine conditions are found near summits and along ridges. The trail reaches more than half of the four-thousand footers of New Hampshire, including Mount Washington, the highest point of the AT north of Tennessee. The Dartmouth Outing Club maintains the AT from the Vermont border past Mount Moosilauke to Kinsman Notch, with the AMC maintaining the remaining miles through the state. The 281 miles (452 km) of the trail in Maine are particularly difficult. More moose are seen by hikers in this state than any other on the trail. The northern terminus of the Appalachian Trail is on Katahdin's Baxter Peak in Baxter State Park.
The western section includes a mile-long (1.6 km) stretch of boulders at Mahoosuc Notch, often called the trail's hardest mile. Also, although there are dozens of river and stream fords on the Maine section of the trail, the Kennebec River is the only one on the trail that requires a boat crossing. The most isolated portion in the state (and arguably on the entire trail) is known as the "100-Mile Wilderness." This section heads east-northeast from the town of Monson and ends outside Baxter State Park just south of Abol Bridge. Park management strongly discourages thru-hiking within the park before May 15 or after October 15.[ The AMC maintains the AT from the New Hampshire border to Grafton Notch, with the Maine Appalachian Trail Club responsible for maintaining the remaining miles to Mt. Katahdin.
