About this map

Yesmowit Canyon and the surrounding drainages of Yakima County define this landscape on the Yakama Indian Reservation. The map documents a complex system of ridges and seasonal watercourses, including the prominent Ahtanum Ridge and Rattlesnake Ridge. The presence of Soda Springs and its namesake Soda Springs Canyon suggests the unique hydrogeology of the area, where water emerges amidst the deep cuts of N Fork Simcoe Cr and S Fork Simcoe Cr.

Bureau of Indian Affairs roads, such as Bia 52 RD and Bia 8 RD, provide the primary access through this high-desert terrain. The network of canyons, including Whitefoot Canyon and the curiously named Old Maid Canyon, illustrates the erosional patterns of the watershed. Researchers can trace the path of Wahtum Cr and Diamond Dick Cr as they navigate the breaks between Sedge Ridge and the lower plateaus.
