Ritter Hot Springs and Powell Hot Springs anchor the settlement of Ritter at the confluence of several vital watercourses. The landscape is defined by the canyon systems of the Middle Fork John Day River and North Fork John Day River, which cut through the high country of the Umatilla National Forest. Notable landmarks such as Devils Backbone and Zion Scope illustrate the complex topography that historically directed movement through this portion of Grant and Umatilla counties. Local history is preserved at the Ritter Cem and the Dickerson Ranch, while the network of county roads, including Ritter Rd Co Rd 15 and Long Creek Rd, shows the established routes connecting these valley settlements to the broader region. The map details numerous named drainage systems like Twelvemile Cr and Thompson Cr, essential for understanding the early agricultural and ranching footprint in the area.
