About this map

Sage Cr and Russell Cr define the hydrological character of this Hill County landscape, where the prairie is carved by seasonal drainage systems. The terrain is marked by the prominent rise of Black Butte in the southeast, a significant navigational landmark in an area otherwise defined by wide horizons and coulees.

Transportation in the region follows a rigid section-line grid, typical of the Great Plains' public land survey system. Hwy 255 serves as the primary north-south artery, intersected by gravel and dirt roads such as Rd 190 N and Rd 140 N. This 2020 survey illustrates the enduring agricultural layout of the Montana High Line, showing the relationship between water courses like Flat Coulee and the rural road network that supports the surrounding farmsteads.
