About this map

Calico Ranch and its associated Corral anchor the southern portion of this high-desert landscape where the border of Oregon and Nevada meets the line between Malheur and Humboldt Counties. This 1980 edition captures a remote grazing and water-resource network defined by numerous perennial sources, including Mahogany Spring, Willow Spring, and Calico Spring. The topography is dominated by the prominent Calico Butte and the long incline of Mahogany Ridge.

Water management for livestock is evident at Owyhee Reservoir No. 4, while the natural drainage system of Mahogany Creek, Wild Bills Creek, and Piccolo Creek carves through the terrain. A network of labeled Jeep Trails and standard trails provides the primary means of navigation through this isolated pocket of the Great Basin, connecting the ranch site to geological features like the Caves located along the creek bluffs.
