About this map

Pryor Gap serves as a primary geographic focal point in this portion of Big Horn County, where the transition between high mountain terrain and creek-fed valleys is clearly defined. The landscape is dominated by the massive presence of West Pryor Mountain and the Pryor Mountains to the south, creating a natural corridor for drainage and travel. The network of waterways, including Bird Creek, Pryor Creek, and Summit Creek, dictates the placement of early infrastructure.

Evidence of local water management is visible through the presence of the Lost Creek Ditch, reflecting the necessity of irrigation in this environment. Transportation routes like Pryor Gap Rd and Pryor Creek Rd follow the natural contours of the land, connecting landmarks such as Castle Rocks and Crown Butte. This survey provides a modern spatial record of the traditional routes and named topographic features that have long shaped the identity of this Montana range.
