About this map

Mission Coulee serves as the central geographic feature of this 2017 survey, where the drainages and high points of Big Horn County form a distinctive network of draws and ridges. The landscape is defined by its numerous coulees, such as West Dipping Vat Coulee and Ash Coulee, which channel runoff toward seasonal water bodies like Rotten Grass Cr in the northeast and Dry Soap Cr to the southwest.

Evidence of local navigation and land use is visible through the path of Good Luck Rd, which skirts the eastern ridges. Named landmarks like Rattlesnake Butte and the broad Cooper Basin provide essential orientation points for those studying the topography of this part of Montana. The map reflects a landscape of open range and complex drainage patterns, with the names of several coulees, including Eychaner Coulee and Cottonwood Coulee, likely carrying the legacy of early ranching families or local natural history.
