About this map

The Milk River valley defines the southwest corner of this northern plains landscape, where the river's winding path is shadowed by Riverside Dr and Riggin Rd. This Valley County terrain is dominated by a complex network of drainage systems, including the map's namesake Chapman Coulee and the extensive Richardson Coulee. The topography illustrates the harsh, water-carved character of the region, featuring numerous seasonal watercourses like Spring Creek and Wire Grass Coulee.

Transportation through these breaks is maintained by a grid of rural routes such as Cornwell Rd and the long-stretching Jensen Trl, which connects the northern plateaus toward Martin Coulee. This 2020 survey provides a modern view of the Public Land Survey System divisions, from T30N R38E through T29N R39E, documenting how ranching and land management access roads have adapted to the deep incisions of Alkali Coulee and Mooney Coulee.
