 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

 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.) Later, Shaffer also completed the first north-to-south thru-hike (all documented thru-hikes before that had been south-to-north). In 1998 Mr. Shaffer, nearly 80 years old, again hiked the entirety of the trail, making him the oldest person ever to complete a thru-hike.

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 Trail

Plants

Plant life along the trail is varied. The trail passes through several different biomes from south to north, and 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 in Massachusetts and The Hermitage

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. 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 the best weather, which typically occurs between May and September.

Navigation

Throughout its length, the AT is marked by 2-by-6-inch (5-by-15-cm) white paint blazes
Trail blazing

Trail blazing is the practice of marking paths in outdoor recreational areas with blazes, markings that follow each other at certain — though not necessarily exactly defined — distances and mark the direction of the trail....
. Side trails to shelters, viewpoints and parking areas use similarly-shaped blue blazes.

In past years, some sections of the trail also used metal diamond markers with the AT logo, few of which survive.


Lodging

The trail has more than 200 shelters and camp sites available for hikers. The shelters, sometimes called lean-tos (in Maine, Massachusetts, and Connecticut), huts (in Shenandoah National Park and the White Mountains in New Hampshire) or adirondack shelters, are generally open, three-walled structures with 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
Outhouse

The term outhouse usually refers to a type of toilet in a small structure separate from the main building which does not have a Flush toilet and is not attached to a Sanitary sewer....
. They generally have spaces for tent sites in the vicinity.

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."

In addition to official shelters, many persons offer their homes, places of business, or inns to accommodate AT hikers. One example is the Little Lyford Pond camps

The Little Lyford Pond camps opened in 1874, bordering the West Branch Pleasant River in northern Maine in the United States. The camps are a 2.2 mile hike from Gulf Hagas and a 5.2 mile hike from the Appalachian Trail's famed 100-Mile Wilderness....

Trail towns

Trail magic is sometimes done anonymously. In other instances, persons have provided food and cooked for hikers at a campsite.

Hazards

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 fellow humans encountered along 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. Ticks are carriers for Lyme disease

, including murder, has occurred on the trail in a few instances. Most have been crimes by non-hikers who crossed paths relatively randomly with the AT hiker-victims. The official website of the Appalatian Trail Conservancy points out that the number of violent crimes is extremely low when compared against the number of people (3 to 4 million) who hike on the trail every year.

Nine homicides have been documented on the trail since the first reported homicide in Georgia in 1974. 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 the trail in Shenandoah National Park

Trail completion

Anst Triangle Logo 1
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. Traditionally, only about 10% to 15% of those who make the attempt report to the Appalachian Trail Conservancy that they completed it. However, since 2001, the number of people starting out in Georgia to do a thru-hike (or at least registering to do so) has dropped considerably, yet the number of people reporting that they have completed a thru-hike has remained approximately the same. This has resulted in an apparent increase in the completion rate to 29% (as of 2006). Considering that the rangers station at Amicalola Falls (the beginning of the approach trail to Springer Mountain) had changed its policy on hiker registration at about the same time, it is possible that the drop in thru-hikers starting out is only a perceived drop due to a change in reporting. As of 2007, the total number of reported thru-hike completions since the 1930s was 9,583. 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 typically tackle the AT with automobile support teams, without backpacks, and without camping in the woods.

The current unofficial speed record for through-hiking the AT was set by trail runner Andrew Thompson in 2005, at 47 days, 13 hours and 31 minutes. Thompson made the trip southbound, from late June to early August.

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. There are also those who hike the trail in sections known as "sectioners" as opposed to those who hike the whole trail as one course.

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 (NOrthBOund) or GAME (Georgia(GA)-to-Maine(ME)), while those heading in the opposite direction are termed "south-bounders" (also SOBO or MEGA).

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, operates on 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.

Most of the trail is also open to local use.
