The valley was named as such due to how Horn Mountain curved in a way that it formed a pocket.
The facilities at The Pocket include a campground, picnic area, and hiking trails.
The valley was formed when weaker limestone eroded and left the surrounding iron ore ridges.
By 1941, as the problem of unemployment diminished, funding for the CCC was discontinued and the Pocket Camp was closed.
The camp's buildings were demolished following the closure; only the foundation of the springhouse and the floor of a large shower house still exist.
