About this map

The Redwater River winds through this section of the High Plains, carving a landscape defined by the drainage networks of Sullivan Coulee and Milne Coulee. This 2020 survey documents the border region between McCone and Richland counties, where the terrain is marked by deep coulees and intermittent creeks such as Muskrat Cr and Davis Coulee. The mapping of these drainages reveals the hydrological pattern of a semi-arid environment where water determines the contour of the land.

Human presence is reflected in the section lines and rural road networks that follow the cardinal directions across the township boundaries. Local history is centered at Grandview Cem near Co Rd 142, providing a touchstone for genealogical research in this part of eastern Montana. The map traces several arterial routes including Sunnyside Rd and Doornek Rd, which connect the isolated homesteads and ranch lands characteristic of the area.
