About this map

Chilkoot Coulee cuts a distinct path through the dissected high plains of the Yellowstone and Big Horn county border. This survey from the early 21st century reveals a landscape primarily defined by its drainage network and high ground, such as Wild Horse Ridge. The topographic relief is shaped by a series of intermittent and perennial watercourses, including the Cottonwood Cr, Hay Cr, and the broader drainage of E Pryor Cr.

Remote transit is limited to unpaved routes like the Pryor-St Xavier Rd and Pryor-St-X-Rd, which navigate the complex ridges and coulees. The map serves as a detailed record of the public land survey system, clearly delineating the sections of Township 4 South, Range 27 East and surrounding blocks. For those studying the hydrology of the region, the confluence of Big Woody Cr and its western fork provides a clear look at the area's natural drainage patterns.
