The John Day River carves a winding path through this corner of Sherman County, creating a landscape defined by deep drainages and isolated plateaus. In the early 21st century, this area remains characterized by large-scale ranching and remote infrastructure, notably the Kaseburg Ranch and the nearby Ajax Airstrip. The river's influence on travel is evident at the Cottonwood Bridge, a vital crossing point in a region where steep terrain features like Ruggles Grade and Taylor Grade dictate the movement of goods and people.
