About this map

Corporation Rim dominates this high desert landscape, carving a distinct geological edge through Harney County. The distribution of vital water resources in this arid environment is clearly documented, from the Corporation Lake near the rim's base to specialized catchments like Bacon Camp Waterhole and North Desert Waterhole. These features, along with Gamble Reservoir and Wagon Reservoir, underscore the critical infrastructure required for land management and ranching in the region.

Topographical interest is concentrated along the dramatic rises of Three Story Rim and the descent into Warner Valley. The map also traces a network of remote access routes, including Nasty Flat Rd and various forest development roads, which connect isolated points such as Little Steamboat Point and Black Cap. The inclusion of small-scale features like Lynch Gulch and Kit Canyon provides granular detail for local historians studying land use and historical grazing patterns.
