Shoestring Ridge and the complex drainage systems of the John Day River define this high-desert plateau along the Sherman and Gilliam County line. The landscape is carved by deep water-cut features such as Thirtymile Creek and Buckskin Canyon, which emphasize the high relief between the river basin and landmarks like Nelson Butte and Table Rock. This modern survey illustrates how long-established rural paths like Richmond Road and Armstrong Canyon Road navigate the difficult terrain of the Columbia Plateau.
