Och Oco National Forest encompasses this high-elevation landscape in Harney County, characterized by a complex network of water management features and drainage systems. This 1990s survey reveals a managed wilderness where industrial history and natural hydrology meet, evidenced by the presence of the Mill Reservoir, Sawmill No 2 Reservoir, and Sawmill No 1 Reservoir. These catchments, along with several named stock ponds, underscore the area's importance for timber or ranching interests during the late twentieth century. Landforms like Corral Ridge and Chapin Table define the verticality of the terrain, while numerous water sources such as Soda Spring and Gilchrist Spring feed into major arteries like Silver Creek and Delintment Creek. The map provides an essential record for tracing the development of Forest Service infrastructure, including named points like Howard Point and the distribution of localized reservoirs like Twin Spring Reservoir.
