About this map

Murnions Reservoir sits as a central water feature in this portion of Garfield County, marking a landscape defined by the drainage networks of the Missouri River basin. The terrain is deeply etched by numerous seasonal watercourses and topographic depressions, including Sonny Coulee, Allen Coulee, and Spring Draw. These features, along with larger creek systems like Big Dry Cr and Ada Cr, illustrate the complex erosion patterns typical of the Montana plains.

Transportation through this ranching country is represented by Ross Rd, which navigates the high ground between watersheds. The map details the transition between multiple townships, including t18n r40e and t19n r41e, providing a clear record of land division in this rural area. Water sources remain the primary landmarks for local history and land use, with Big Wild Horse Cr and Frazier Cr serving as significant geographic anchors for the surrounding range.
