About this map

Volcano Reef rises as the dominant landmark in this Montana landscape, where the plains meet the high country of the Lewis & Clark National Forest. The map documents a complex drainage system defining the Teton County terrain, including the headwaters of the Middle Fork Dry Fork Marias River and several branches of S Fork Dupuyer Cr. The land is deeply etched by numerous coulees, such as Toms Coulee and Ben English Coulee, which serve as natural landmarks for local ranchers and land managers.

A network of local ranch roads, including TRM Ranch Rd and Evan Campbell Rd, provides access across the transition from open range to the dramatic entrance of Blackleaf Canyon. The presence of numerous land parcels, noted as PB 37 through PB 45, reflects the continuing legacy of the Public Land Survey System in organizing this corner of the American West. The geography here is defined by the sharp contrast between the established watercourses like Blackleaf Cr and the dry, named coulees that crisscross the foothills.
