Ritter and its surrounding river valleys define this portion of the Oregon backcountry, where the Middle Fork John Day River and the North Fork John Day River wind through complex terrain. The map highlights the thermal geography of the region, specifically Ritter Hot Springs and Powell Hot Springs, which have long served as focal points for the local community. These natural features are joined by several named drainages including Threemile Creek, Eightmile Creek, and Twelvemile Creek, suggesting a landscape once measured by the distance of its waterways.
