From reverse of photograph: "Replacing the Roof on the East Carry Pond Lean-to (1954)" The East Carry Pond Lean-to is one of the many Ghost Shelters along the Appalachian Trail. In this photograph from 1954, one can see that it was a small log sided lean-to structure with a shingle roof and a dirt floor. It was maintained by the Maine Appalachian Trail Club.

The Bigelow Mountain Shelter, pictured here sometime in the 1950s, was removed from the Appalachian Trail in the 1960s. It is a typical version of the log sided Adirondack style lean-to favored by the early shelter builders. It was located just south of the current Horns Pond Shelter.

The Poplar Ridge Shelter in Maine is a traditional Adirondack style lean-to, maintained by the Maine Appalachian Trail Club. The description on the reverse of the image reads: "Poplar Ridge Lean-to, an ideal resting place."
