About this map

The Crow Indian Reservation Boundary cuts across this high-elevation landscape, marking a transition between reservation lands and the protected terrain of the Bighorn Canyon National Recreation Area. The topography is dominated by dramatic drainages that feed into the southern reaches of Bighorn Lake, which is recorded here at a normal pool elevation of 3640 feet. Deep incisions like Frozen Leg Canyon and Black Canyon define the area's geological character, while Grapevine Dome stands as a prominent landmark to the northwest.

Evidence of ranching and remote operations appears at The Forks Cow Camp, situated near the confluence of the North Fork and South Fork of Grapevine Creek. This 1963 survey, later updated with 1980 aerial revisions, captures the Missouri River Basin development era, particularly the formation of the reservoir landscape behind the Yellowtail Dam. Numerous unnamed springs and the sprawling Cooper Ridge highlight the complex water-carved environment of the Big Horn region.
