About this map

Three Buttes dominates the southeastern quadrant of this Valley County landscape, rising above a network of seasonal drainages and prairie roads. This 2020 survey illustrates the remote character of the Frazer District, where the terrain is shaped by the winding paths of Oswego Cr and its tributaries, including the E Fork Oswego Cr. The presence of Structure Number 143 Reservoir in the northwest suggests the vital role of water management in this arid grazing land.

A sparse grid of section lines and local roads like Frazer-Richland Rd and Oswego Creek Rd provide the only infrastructure across these hills. To the north, the terrain dips into the Badger Hole Coulee, a significant topographic depression. This map is a primary resource for understanding contemporary land use and topographic change in this corner of Montana, documenting the persistent rural character of the Big Sky country.
