About this map

Yesmowit Canyon and the surrounding drainage basins of Yakima County are defined by a rhythmic sequence of ridges and deep canyons. This area of Washington is characterized by significant topographic relief, where Ahtanum Ridge and Sedge Ridge overlook a complex network of seasonal and perennial watercourses. The drainage patterns are clearly visible through the paths of N Fork Simcoe Cr and S Fork Simcoe Cr, which have carved out features like Old Maid Canyon and Whitefoot Canyon.

Historically rooted in land management, the map shows a landscape primarily accessed by Bureau of Indian Affairs routes like Bia RD 147 and Bia RD 4. The naming of features such as Poison Canyon, Hog Canyon, and Soda Springs suggests an era of early settlement and livestock management where water sources and distinct landforms were vital navigation markers. The prevalence of names like Rattlesnake Canyon and Rattlesnake Ridge further highlights the local environmental characteristics that shaped early activity in this part of the Pacific Northwest.
