The Continental Divide National Scenic Trail winds through this high-altitude landscape, marking the physical boundary between Beaverhead National Forest in Montana and Salmon National Forest in Idaho. This 2020 survey reveals a complex drainage network where Bloody Dick Cr and its many tributaries, such as Lake Cr and Kitty Cr, carve through the mountainous terrain. The map captures the meeting of Beaverhead and Lemhi counties, anchored by significant topographical features like Pyramid Hill and deep valleys including Hughes Gulch and Hamilton Gulch. Grounded in the backcountry infrastructure of the era, the sheet details numerous forest routes like Bloody Dick Rd and Warm Springs Rd, along with remote water sources such as Pyatt Springs, essential for understanding the modern accessibility and conservation boundaries of this section of the Rocky Mountains.
