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.
