2011 Map of Medicine Valley

About this map

Medicine Valley is the primary geographic feature of this Yakima County landscape, defined by an intricate network of waterways and canyon systems. The valley floor is shaped by the confluence of North Medicine Creek and South Medicine Creek, while further south, the Simcoe Creek drainage is supported by infrastructure like the White Swan Mill Ponds Dam near Agency Creek. This 2011 survey captures the area's rural road network, dominated by Bureau of Indian Affairs routes such as BIA 4 Rd and BIA 12 Rd, which connect the scattered canyons and valleys. The presence of Yesmowit Cemetery near the center of the quadrangle provides a significant anchor for local history and genealogical research. The northern reaches are more topographically diverse, featuring Poison Canyon, Hog Canyon, and the headwaters of Patemas Creek, showing the transition from higher terrain into the fertile valley bottom.
