2024 Map of Mission Coulee

About this map

Rattlesnake Butte rises as a prominent landmark in this section of Big Horn County, overseeing a landscape defined by its complex drainage network and coulees. The map traces the winding course of Rotten Grass Creek through the northeastern corner, while Cottonwood Coulee cuts a deep path through the center of the quadrangle. This area is characterized by high-plateau terrain and deep basins, most notably the wide expanse of Cooper Basin near the southern boundary. Human infrastructure is sparse in this portion of the Montana landscape, represented primarily by the descriptive Good Luck Rd and the geometric precision of the Public Land Survey System. The interplay of named features like Ash Coulee and Cooper Basin Coulee reflects a traditional western geography where water and elevation dictate the shape of the land.
