2017 Map of Summit Ridge

About this map

Summit Ridge and the deep drainage systems of the eastern Oregon high country define this landscape south of the Columbia River. The map documents a complex network of topographic features, where the Deschutes River carves through the southeastern corner, forming a natural boundary between Wasco and Sherman Counties. The terrain is marked by numerous named canyons and hollows, such as Windmill Canyon, Burn Canyon, and Stubb Hollow, which indicate a history of land use and water management in a semi-arid environment.
