The Cosby Knob Shelter is in the Great Smoky Mountains National Park and is the next to last shelter northbound in the Park. It is maintained by the Smoky Mountains Hiking Club.

The Carter Gap Shelter is the third shelter on the Trail north of the Georgia/North Carolina line. This image is of the older version of the shelter. There is now a second, newer Carter Gap Shelter closer to the Trail.

The Springer Mountain Shelter is located near the southern terminus of the Appalachian Trail. This image is of an older incarnation of the shelter. The Georgia Appalachian Trail Club tore down this version of the shelter and replaced it with the larger version that hikers encounter today.

The Hawk Mountain Shelter in Georgia is located in the Chattahoochee National Forest, about eight miles north of the southern terminus of the Trail at Springer Mountain. As a result, it is often the first stop for northbound hikers. This image shows the shelter as it was in 1974. It has subsequently been rebuilt by the Georgia Appalachian Trail Club.

The Wilson Gap Shelter was built in 1941, by the Potomac Appalachian Trail Club's shelter crew. It was an atypical trail shelter, because it was built of stone, with an internal fireplace. This particular design happened because the landowner felt that such a structure would present less of a fire hazard on his land. It was the second trail shelter south of the Potomac River, near the present Blackburn Trail Center. It no longer exists, because by the late 1970s, its proximity to a county road meant it had become a party location for non-hikers. It was torn down in 1978.

The Three Springs Lean-to (shelter) in Northern Virginia was located on a stretch of the Trail just north of FEMA's Mount Weather Emergency Management base. This shelter no longer exists, because in the late 1970s the Trail was relocated away from the site and the shelter was torn down. It was maintained by the Potomac Appalachian Trail Club.

The Birch Run lean-tos were built in 1934 by workers from the Civilian Conservation Corps (CCC) in the Michaux State Forest in Pennsylvania. Like other shelters in this stretch of the Trail, these lean-tos were constructed in pairs of smaller shelters, rather than as one larger shelter. The original structures were torn down in the 1980s, and replaced with a single, larger shelter. These shelters were and the new shelter is maintained by the Potomac Appalachian Trail Club (PATC).

The Racoon Run Shelters in the Michaux State Forest (PA), were built by workers from the Civilian Conservation Corps (CCC) in 1934. Smaller than the standard Appalachian Trail lean-tos built at this time, the paired shelters in this stretch of the Trail in Pennsylvania are unique along the Trail. The Raccoon Run Shelters were maintained by the Potomac Appalachian Trail Club, but they were torn down in the 1980s when the AT was relocated away from its current route. The Raccoon Run Shelters were among those too close to the road, and often frequented by non-hikers.

The map shown here is from the PATC Map No. 4 (1980) and it depicts the location of the shelters on the old route of the AT. This image was provided by Stuart O. Smith, Jr.

The Quarry Gap shelters in Michaux State Forest (now Caledonia State Park) were built in 1934 by workers from the Civilian Conservation Corps (CCC). The trail shelters in Michaux State Forest at this time were unique in that they were built as pairs of smaller structures rather than one larger lean-to. At some point in their history, the Quarry Gap shelters were re-roofed with a single, continuous roof, providing shelter for hikers between the two structures. These shelters are maintained by the Potomac Appalachian Trail Club.

Pocosin Cabin in Shenandoah National Park was built the Civilian Conservation Corps (CCC) in 1937 as temporary housing for workers during the construction of Skyline Drive. Following the completion of the Drive the cabin was turned over to the Potomac Appalachian Trail Club (PATC), which has since maintained it as a reservation-only cabin for hikers.

The No Business Knob Shelter is located in the Cherokee National Forest near Erwin, Tennessee. It is a concrete sided lean-to of the type constructed in a number of locations in North Carolina and Tennessee. This shelter is maintained by the Tennessee Eastman Hiking and Climbing Club.

Volunteers and officials of the U.S. Forest Service at the dedication of the Niday Place AT Shelter on August 26, 1962. The Niday Place Shelter is a typical example of the plank sided lean-to favored by the U.S. Forest Service. It is located in the Jefferson National Forest in Virginia, south of Roanoke, and is maintained by the Roanoke Appalachian Trail Club.
