About this map

Oregon Canyon Mountains dominate this high-desert landscape in southeastern Oregon, where a sophisticated network of small-scale water management features supports ranching operations. Numerous named catchments, such as Pretty Rock Reservoir and Pinky Reservoir, are situated near the seasonal drainage of Indian Creek. The map documents the presence of family-named infrastructure and access routes, including Archie Myers Ranch Rd and Myers Reservoir, reflecting the historical footprint of livestock production in this arid corner of Malheur County.

The terrain is defined by dramatic volcanic and erosional features, from the heights of Mendi Suri and the plateau of Flattop to deep incisions like Fish Creek Angel Canyon. Industrial and mining history is represented by the Bretz Reservoir, located near the historic mercury mining district. Transportation across these canyons relies on a network of unpaved tracks like Disaster Peak Rd and Fifteenmile Reservoir Rd, which follow the natural contours of the land.
