The John Day River carves a winding path through this arid landscape, defining the boundary between Wasco and Wheeler counties. At the heart of the region lies the John Day Fossil Beds National Monument, where dramatic geological formations such as The Palisades, Clarno Arch, and Black Spur rise from the desert floor. The small settlement of Clarno serves as the primary hub along Or-218, situated near the turbulent Clarno Rapids. For those researching local history, the area contains significant burial sites including Clarno Cem and the Tillotson Cem near the banks of the river. The terrain is deeply incised by numerous drainages, including Equisetum Canyon and Hancock Canyon, while landmarks like Iron Mtn and Whitecap Knoll provide distinct vertical relief. The proximity of Willow Branch Spring highlights the importance of water sources in this high-desert environment.
