The John Day River flows through the northern reaches of this Grant County terrain, carving a path past the Cheechako Ranch and the historical site of the Aldrich Grave. This high-elevation landscape is defined by the massive uplift of the Aldrich Mountains, where peaks like Aldrich Mtn and Little Aldrich Mtn overlook a complex network of drainages. Evidence of early land management and water engineering is found in the Stewart Ditch, which follows the contours of the river valley.
