1992 Map of Aldrich Gulch

About this map

Black Canyon Wilderness dominates this Grant County landscape, showing a complex network of canyons and high ridges within the Och Oco National Forest. The hydrology of the region is defined by the South Fork John Day River and a series of high-elevation water management features, including Seven Sixty Reservoir, Ringsmeyer Reservoir, and Wigwam Reservoir. These man-made catchments, alongside springs like Soup Spring and Twin Stoves Spring, suggest the critical importance of water storage for the remote ranching operations scattered throughout the terrain.
