2017 Map of Coombs Canyon

About this map

Coombs Canyon and Mud Spring Canyon carve through this section of Umatilla County, defining a landscape marked by significant elevation changes and deep drainage basins. The area is dominated by the transition between several public land survey townships, including t2n r31e, t1n r31e, and t1s r31e. Settlement patterns are traced through a network of rural roads often bearing the names of local families, such as Redwine Rd, Reinhart Rd, and Hoeft Rd. Water sources are vital in this high-desert environment, evidenced by the named Crazy John Spring and the presence of numerous canyons. This 2017 survey illustrates the modern configuration of access roads like Speare Canyon Rd and Stock Dr Rd as they navigate the ridges and valleys of the region south of the Columbia River plateau.
