About this map

The Milk River meanders through this portion of Phillips County, carving a distinct hydrological pattern characterized by the prominent Big Bend and numerous tributary drainages. The landscape is defined by its coulees and sags, reflecting the erosional history of the Montana plains. Notable terrain features include Butte Coulee and Martins Coulee to the north, while Lone Tree Sag sits near the southern margins, adjacent to the northern reaches of the Nelson Reservoir.

Infrastructure is focused on the river valley, with Milk River Rd and River Rd providing the primary access through the township sections. Small seasonal drainages such as Little Cottonwood Cr and Spring Coulee underscore the area's reliance on the central river system for drainage and irrigation, a critical component of the local agricultural and ranching geography in this northern prairie environment.
