Imnaha Falls and the headwaters of the Imnaha River dominate this high-elevation landscape where the Wallowa National Forest meets the Whitman National Forest. The 1990 survey captures an intricate network of alpine water management and recreational infrastructure, featuring numerous water bodies such as Sugarloaf Reservoir, Fish Lake, and Twin Lakes. The terrain is defined by dramatic peaks like Russel Mountain and Deadman Point, while the presence of the Buchanan Ditch, Greener Ditch, and Weatherspoon Ditch highlights historical efforts to divert water through these steep basins.
