Ritter is the central settlement in this high-desert landscape, situated where the Middle Fork John Day River meets the geothermal activity of the region. The map identifies both Ritter Hot Springs and Powell Hot Springs, landmarks that have historically drawn travelers to this reach of the river. The terrain is marked by deep incisions such as Wrightman Canyon and Deep Canyon, while the Devils Backbone provides a prominent ridge between drainage systems.
