Ochoco Reservoir dominates the drainage system of this Central Oregon landscape, where the waters of Ochoco Creek and Mill Creek are impounded within the Ochoco National Forest. The 1948 field survey reveals a high-desert ranching and timber economy characterized by isolated outposts such as Keystone Ranch and the Lakin Place. Local education is anchored by rural schoolhouses including Mill Cr Sch and Howard Sch, serving families spread across the ridges. Geologically striking features like Steins Pillar and Twin Pillars rise sharply from the terrain, while the network of springs, from Kidnap Spr to Salt Butte Spr, indicates the vital importance of water sources in this environment. The presence of the Cabin Guard Sta and various corrals like Slayton Corral underscores the managed nature of the forest and rangeland during the mid-century.
