The Umatilla River carves a deep valley through this portion of Umatilla County, creating a dramatic corridor for the settlement at Thorn Hollow. This landscape is defined by its deep canyons and named ridges, including Red Elk Canyon, Shaplish Canyon, and Kanine Ridge. The presence of the Red Elk Cem and Reservation Mtn points to the cultural and geographic heritage of the region, while the Thorn Hollow Grade indicates the challenging transport routes required by the local topography.
