About this map

The small settlement of Blackleaf sits in Teton County, positioned where the high plains meet the intricate drainage systems of the Rocky Mountain Front. This 2017 survey details a landscape defined by sharp coulees and the headwaters of the Marias River system. Waterways like Blackleaf Cr and the Middle Fork Dry Fork Marias River carve through the terrain, illustrating the natural irrigation patterns that have long dictated ranching and settlement in this part of Montana.

Local landmarks often bear the names of early inhabitants or families, as seen in Ben English Coulee, Jensen Coulee, and Gansman Coulee. These features, along with rural routes such as Evan Campbell Rd and Knowlton Rd, provide a modern topographic record of a region where historic land use and geography remain deeply intertwined. The map effectively documents the complex transition from the S Fork Dry Fork Marias River in the north to the N Fork Muddy Cr drainage in the south.
