About this map

Mystery Cave and a series of subterranean landmarks define this portion of the Pryor Mountains along the Montana and Wyoming border. Located within the Custer National Forest, the landscape is characterized by deep drainages like Lost Water Creek Canyon and Burnt Timber Canyon. The eastern edge of the survey area captures the dramatic descent into Bighorn Canyon, where the Bighorn River forms Bighorn Lake as it passes through the Crow Indian Reservation.

Evidence of subterranean exploration is frequent, with named sites such as Royce Cave, Froggs Fault Cave, and Four Eared Bat Cave scattered across the high terrain. Human activity in this remote area is primarily represented by several scattered Prospects and a Mine located near the head of a Jeep Trail, reflecting the mid-century intersection of recreation, mineral exploration, and resource management within the Bighorn Canyon National Recreation Area.
