Corral Butte stands as a prominent landmark in this high-altitude landscape of the Okanogan Highlands, where the Okanogan National Forest meets the Loomis State Forest. The map documents a complex hydrological system defined by the diverging headwaters of several major drainages, including Middle Fork Toats Coulee Creek and multiple branches of Twentymile Creek. The terrain is characterized by high meadows and seasonal wetlands, most notably Thirtymile Meadows and Long Swamp, which likely served as critical points for early land management and grazing.
