2017 Map of Red Pryor Mountain

About this map

Red Pryor Mtn and the southern reaches of the Pryor Mountains dominate this landscape within the Custer National Forest. The map details a complex system of drainage and relief, where Crooked Cr and Lost Water Cr carve deep through the terrain. Evidence of the area's geological and cultural significance is found in the naming of Petroglyph Canyon in the far southwest corner, while livestock or utility history is suggested by the presence of Commissary Ridge and Commissary Cr. Access to this high-altitude region is limited to primitive routes like Helt Rd and Gyp Springs Rd, which navigate between prominent landmarks such as Penney Peak and Island Ridge. The transition from the high ridges down to Demijohn Flat illustrates the drainage patterns characteristic of the Montana-Wyoming borderlands.
