2020 Map of Castle Rocks

About this map

Pryor Gap serves as a prominent natural passage through the high-elevation terrain of Big Horn County, as documented by the United States Geological Survey. This 2020 topographic record highlights the complex relief of West Pryor Mtn and the namesake Castle Rocks formation, which dominate the central landscape. The area is defined by sharp elevation shifts between ridges and the drainage basins of Pryor Cr and Bird Cr, illustrating the importance of natural corridors in this part of the Pryor Mountains. Historical water management is evident in the presence of the Lost Cr Ditch, while modern connectivity is maintained by Pryor Gap Rd. Further south, Crown Butte stands as a distinct landmark near Summit Cr, marking the rugged transition towards the southern reaches of the range.
