The Darlington Shelter in Pennsylvania is a replacement for the original Darlington Shelter built in 1956 by Earl Shaffer, the first person to thru hike the Appalachian Trail in 1948. The shelter Shaffer built was replaced by the current structure in 1977 by the Mountain Club of Maryland, which still maintains the shelter. The shelter is named for Bishop James Henry Darlington, an early advocate of the Appalachian Trail.
