The Rentschler Shelter was located in Pennsylvania near Bethel, PA, and was built by volunteers from the Blue Mountain Eagle Climbing Club to commemorate Dr. Rentschler's role in founding their club. The shelter was built in 1933 and torn down in the 1960s. It was a partially closed front log lean-to, typical of the shelters built during this period in Pennsylvania, Virginia, and Maryland. A memorial to Dr. Rentschler remains at the site of the former shelter.

The Bake Oven Knob Shelter was built in 1937 and the current shelter is still that original structure.

It is currently maintained by volunteers from the Blue Mountain Eagle Climbing Club.

The Applebee Cabin in Pennsylvania during a weekend hike by members of the Philadelphia Trail Club. The cabin was located on the Appalachian Trail north of what is now the Hertlein Campsite (formerly the Hertlein Cabin), but was removed in 1971 due to excessive vandalism of the structure. The cabin was built in 1930 by the Blue Mountain Eagle Climbing Club and was maintained by the club until its removal from the Trail.
