The Blackrock Hut (Shelter) is located in the southern district of Shenandoah National Park and is an example of the "hut" style of shelter, built from stone and logs. This shelter was completed in June 1941 and the current shelter is the original structure from 1941.

This particular image depicts a moment in the history of the park and its trail shelters when hikers were banned from overnight camping at or within site of the shelters. The sign leaning against the wall reads, "Overnight camping at or within sight of this shelter is prohibited." The camping prohibition was the result of the Park Superintendent's concern that the AT shelters had become party locations for Park visitors. His closure of the shelters was a point of contention between the Park and the Potomac Appalachian Trail Club throughout the 1970s, after which the camping ban was relaxed.
