About this map

The Humboldt National Forest anchors the southern portion of this landscape, where the high-elevation terrain of the Calico Mountains and Odell Mountain overlooks the drainage of the East Fork Quinn River. This 1980 survey captures the high desert borderlands between Nevada and Oregon, specifically where Mahogany Ridge divides several seasonal and perennial waterways.

A network of Jeep Trails provides the primary means of traversal through this isolated terrain, connecting remote points like Mahogany Spring and Owyhee Reservoir 3. The drainage patterns are well-defined, showing the paths of Mahogany Creek, Piccolo Creek, and Willow Creek as they navigate the ridges and canyons. The map is a valuable resource for understanding the water management and topographic layout of the Malheur and Humboldt County line before modern land-use shifts.
