We were talking about this shelter in another thread, so I thought I'd pull up this old photo (c. 1996). It hasn't changed much over the years - it's small, but it's a welcome retreat from the rain and wind.
Built in 1937, this shelter was the site of BMECC's ceremonies to officially open the section of the Appalachian Trail from the Susquehanna River to the Lehigh River. It may be the oldest shelter on the AT in the mid-Atlantic region.
