About this map

The Deschutes Wild and Scenic River carves a deep, winding path through this corner of North Central Oregon, serving as the natural boundary between Wasco and Sherman counties. This landscape is defined by its dramatic drainage system, where the river loops around Cedar Island while collecting runoff from a dense network of canyons. To the west, Tygh Ridge looms over deep incisions like Oak Canyon, while the eastern plateau is etched by numerous branches including Peterson Canyon and French Canyon. Settled life in this high-desert environment is tied to the limited road network, with routes such as Brown Rd and Payne Loop providing access across the undulating terrain. Small seasonal waterways like Elder Creek highlight the drainage patterns that have shaped the region's topography and agricultural potential over generations.
