2017 Map of Regnal Coulee

About this map

Regnal Coulee and the surrounding drainage basins of eastern Montana define this landscape of high plains and sharp breaks. Situated along the boundary between Garfield and Rosebud counties, the area is characterized by isolated cattle operations and scattered water sources essential for livestock. Prominent topographic landmarks such as McGinnis Butte and McGinnis Butte SW rise above the drainage networks of Big Breed Cr and Beaverhall Cr, while numerous family-named holdings like the Dutton Ranch, Grebe Ranch, and Hecker Ranch illustrate the sparse but enduring ranching footprint. The intricate network of coulees, including Studhorse Coulee and Diego Coulee, highlights the erosional patterns of this arid environment. Key water features such as McWilliams Springs serve as vital nodes in an otherwise dry terrain, supporting the operations of the Yablonski Ranch and Kincheloe Ranch.
