The Catawba Mountain Shelter was built by volunteers from the Roanoke Appalachian Trail Club in the summer and fall of 1984. This shelter was added to the chain of shelters after the relocation of the Appalachian Trail from North Mountain to Catawba Mountain, adding McAfee Knob to the Trail's route. This shelter is built in a style that is reminiscent of the typical plank sided lean-to favored by the U.S. Forest Service, but has unique features in its design, including the peaked roof and more open front. It is maintained by the Roanoke Appalachian Trail Club.

The Three Springs Shelter was located in what is now known as the Roller Coaster section of the Appalachian Trail in Northern Virginia just north of the FEMA Mount Weather Operations Center. Built by the Civilian Conservation Corps in the 1930s on private land, the ownership of this shelter passed to the Potomac Appalachian Trail Club (PATC) in 1969, when the club purchased the shelter and 15 surrounding acres of land, including a section of the AT. This shelter no longer exists. 

The 1941 ATC Guide to the Paths of the Blue Ridge offers this description:

Three Springs Lean-to is situated in a small clearing near the summit of the Blue Ridge on its southeast slope one mile north of Mt. Weather. It occupies the site of the old Ashby farmhouse that had been built early in the nineteenth century. There is a chimney over the fireplace.

At that time, the Appalachian Trail was located on the east side of Blue Ridge Mountain Road, but was later re-routed onto the western side of the ridgeline.

The Big Springs Shelter was located between Mooney Gap and Wallace Gap in the Nantahala National Forest in North Carolina. A plank sided lean-to of the type favored by the U.S. Forest Service, the Big Springs Shelter was removed in 2013 and replaced by the Long Branch Shelter. The new shelter was built and is maintained by the Nantahala Hiking Club. (Location data on the Big Springs Shelter is approximate.)

The Bake Oven Knob Shelter was built in 1937 and the current shelter is still that original structure. It is typical of the log sided Adirondack lean-to design first recommended by the Appalachian Trail Conference during the original construction of the shelter chain. It is currently maintained by volunteers from the Blue Mountain Eagle Climbing Club.

The Ashby Gap Shelter in Northern Virginia was located just west of the village of Paris. Built by the Potomac Appalachian Trail Club in the 1941 on a tract of private land, the shelter was torn down in 1955, when the AT was re-routed away from the site. The 1941 ATC Guide to the Paths of the Blue Ridge offers this description:

Ashby Gap Lean-to is situated in a clearing near the summit of the Blue Ridge on the northwest slope, a little over a mile south of Ashby Gap. It is close to the site of an old cabin.

This undated photograph shows hikers stopping at the Ney lean-to (shelter) at Ney's Gap near Schuylkill, Pennsylvania. This shelter has been removed, but was not far from the current Eagle's Nest Shelter.

Pinefield Hut was built in the summer of 1940 in a style typical to Shenandoah National Park (VA) at this time--a stone base with a wooden roof. This shelter is maintained by Potomac Appalachian Trail Club.

Pass Mountain Hut was built in 1939, and is constructed largely out of stone. It is located in Shenandoah National Park, on the east face of the mountains, about one mile north of Thornton Gap, where Highway 211 crosses Skyline Drive. Today the area around the shelter is heavily wooded, but when it was first built hikers had views up to Mary's Rock above Thornton Gap and into the foothills of Rappahannock County, Virginia. The Pass Mountain Hut was built and is still maintained by the Potomac Appalachian Trail Club.

Smith Gap Shelter (Pennsylvania) under construction in 1948. The was built by members of the Philadelphia Trail Club and was opened to hikers on June 12, 1949. The shelter was built on private land, but in the late 1960s the landowner decided to build a vacation home on the site and turned the shelter into a storage shed. At this time, the Delaware Valley Chapter of the AMC had taken over supervision of the Appalachian Trail in the area from the Philadelphia Trail Club, and Chapter members built a new shelter closer to the Trail in 1973. They dedicated the shelter to their long serving volunteer LeRoy Smith, who passed away shortly after the completion of the current structure.

The Applebee Cabin in Pennsylvania during a weekend hike by members of the Philadelphia Trail Club. The cabin was located on the Appalachian Trail north of what is now the Hertlein Campsite (formerly the Hertlein Cabin), but was removed in 1971 due to excessive vandalism of the structure. The cabin was built in 1930 by the Blue Mountain Eagle Climbing Club and was maintained by the club until its removal from the Trail.

The Crampton Gap Shelter is located near Frederick, Maryland and is one of the original log lean-tos built by the Civilian Conservation Corps in the 1939. It is maintained by the Potomac Appalachian Trail Club.
