About this map

Rattlesnake Butte stands as a prominent landmark in this dissected landscape of Big Horn County, Montana. The topography is defined by an intricate network of deep drainages, including the eponymous Mission Coulee and the adjacent Ash Coulee, which carve through the high plains toward the Rotten Grass Cr watershed. These natural features illustrate the erosional patterns typical of the region, where seasonal water flow has sculpted long-reaching coulees such as West Dipping Vat Coulee and Eychaner Coulee.

Human presence is sparse, marked primarily by the winding Good Luck Rd in the northeastern corner and a handful of ranch-related landmarks. The southern portion of the survey is dominated by the broad Cooper Basin, fed by Dry Soap Cr and the Cooper Basin Coulee. This map provides a detailed record of the physical geography and land divisions before more modern developments, preserving the nomenclature of the local terrain like Cottonwood Coulee.
