2011 Map of Yesmowit Canyon

About this map

Yesmowit Canyon and the surrounding drainage basins of the Yakima region appear here as a network of deeply etched creek beds and Bureau of Indian Affairs roads. The geography is defined by parallel watercourses flowing eastward, including South Fork Ahtanum Creek and Rattlesnake Creek, which cut through the high terrain to form Rattlesnake Canyon. A notable point of interest is Soda Springs, located along the banks of North Fork Simcoe Creek. The map provides a look at the rural infrastructure of the early 21st century, with various access routes like County HWY 5 and Bia 147 RD navigating the divides between Diamond Dick Creek and Wahtum Creek. This layout suggests a landscape managed for resource access and tribal transit, where the naming of even small tributaries like Spencer Creek reflects the specific local importance of water in this arid stretch of Washington.
