2024 Map of Summit Ridge

About this map

Summit Ridge serves as the high spine of this high-desert landscape in Wasco County, where a network of market roads still traces the agricultural patterns of the interior plateau. To the southeast, the terrain drops sharply toward the Deschutes Wild and Scenic River, where the Deschutes River carves through deep basalt layers. This modern survey illustrates how long-established routes like Roberts Market Rd and Summit Ridge Mkt Rd continue to navigate the complex drainage systems of the Columbia Basin. Numerous named canyons, including Jameson Canyon, Fall Canyon, and the deep Ferry Canyon, dissect the ridges, revealing a topography defined by seasonal water flow and structural geology. The map provides clear evidence of the vast, open spaces between the breaks of the Deschutes and the higher agricultural benches.
