The John Day River carves a deep path through the high plateau of the Oregon interior, defining the border between Sherman and Gilliam counties. This landscape is characterized by sharp elevation changes along the river's path, marked by steep descents like Ruggles Grade and Taylor Grade. The Cottonwood Bridge provides a vital crossing near Cottonwood Canyon, where the Cottonwood J S Burres Park Boat Ramp serves as a key access point for river travelers.
