The John Day River carves a deep, winding course through the high plateau of the Oregon interior, defining the border between Sherman and Gilliam counties. This landscape is characterized by a complex network of drainages and topographical features, including the Cottonwood Canyon and the John Day Wild and Scenic River corridor. The map reveals the logistical challenges of the terrain through named passage points such as Ruggles Grade and Taylor Grade, which facilitate movement between the river valley and the upland benches.
