The Raven Rock Shelter was built by the Potomac Appalachian Trail Club (PATC) in 2010 as a replacement for the Devil's Racecourse Shelter, one of the shelters constructed by the Civilian Conservation Corps in the 1930s. Because the Devil's Racecourse Shelter was in need of substantial renovation, and because it had become a preferred location for non-hikers to stage parties (it was close to a road), the PATC decided to build the new shelter much further uphill, away from the road, and close to the Trail.

This shelter, located in Washington County, Maryland, is dedicated to the memory of Ensign Phillip Cowall.

The shelter is located 1054.8 miles north of Springer Mountain (GA) and 1135 miles south of Mount Katahdin (ME).
