Tygh Ridge dominates the northern landscape of this Wasco County quadrangle, where the high basalt plateaus drop sharply toward the Deschutes River. This 2020 survey documents a transition from the agricultural uplands down to the river corridor, a path historically marked by the crossing at Sherars Bridge near the churning waters of Sherars Falls. The intricate network of market roads, including Tygh Ridge Mkt Rd and Old Tygh Mkt Rd, provides a modern look at the routes connecting high-country ranching land to the settlements of Oak Canyon and Buck Hollow. For those tracing local history, the Warner Cem sits on a plateau overlooking the drainage of Dry Cr. The map captures the complex topography of the canyonlands, including deep incisions like Chicken Spring Canyon and Kerr Canyon that define the eastern border with Sherman County.
