The Antietam Shelter, located in the Mont Alto (now MIchaux) State Forest (PA), was built by the Civilian Conservation Corps (CCC) in 1936. It is located on the banks of Little Antietam Creek. Maintained by the Potomac Appalachian Trail Club, this shelter is slated to be moved to a new location, possibly on the Tuscarora Trail, in the near future, due to its proximity to the popular Old Forge Picnic Grounds.
