About this map

The Ochoco Mountains dominate this central Oregon landscape, where the southern reaches of the Ochoco National Forest give way to the winding course of the Crooked River. This 1986 field-checked survey reveals a high-elevation environment defined by water management and resource extraction, evidenced by numerous named water sources like Sand Spring and Pipe Spring. The presence of several quarry sites and a network of 4WD trails suggest a region utilized for both industry and backcountry access.
