2020 Map of Lone Man Coulee East

About this map

The Dry Fork Marias River winds through the high plains of the Teton and Pondera county border, defining a landscape of deep coulees and expansive benches. This modern survey illustrates how traditional ranching and transportation routes continue to follow the natural contours of the Montana front. Named drainage features like Miller Coulee, Lone Man Coulee, and Haatvedt Coulee dominate the northern terrain, while the prominent Castle Rock serves as a distinct geological landmark in the central section. The southern portion of the map is defined by the Benton Bench and the descent into Pondera Coulee. A network of gravel and section-line roads, including Coalmine Rd and Conrad Dupuyer Rd, connects these remote reaches, reflecting the enduring grid-based settlement patterns and land use of the Big Sky Country.
