About this map

The Milk River meanders through the southwestern corner of this Valley County landscape, a vital water source in an area defined by its deep drainage features. The settlement of Chapman Coulee sits as a primary reference point for this territory, where the terrain is carved by numerous secondary coulees including Richardson Coulee, Mooney Coulee, and Alkali Coulee. These geographic depressions shape the movement of water and travel across the plains, with Spring Cr and Cherry Cr feeding into the larger drainage network.

Transport through the region relies on a grid of rural routes and trails such as Jensen Trl and Cornwell Rd. The map also details early 21st-century infrastructure like Nelson Rd and Cut Across Rd, providing a clear record of the local road system as it interfaces with the natural topography. This document serves as a precise accounting of the hydrological and geological features that define ranching and rural life in this part of Montana.
