2015 Map of Mahogany Spring

About this map

The Humboldt National Forest and the Calico Mountains define the high-desert terrain where the borders of Oregon and Nevada meet. This arid landscape is marked by critical water sources such as Mahogany Spring, Rock Spring, and The Trees Spring, which served as vital points for livestock and wildlife across the northern reaches of the Owyhee Desert. The drainage patterns are clearly delineated, showing the headwaters of the E Fork Quinn River flowing westward and several creeks, including Piccolo Cr and Willow Cr, moving toward the Owyhee Reservoir 3. Prominent topographic features like Mahogany Ridge and Foster Draw illustrate the complex elevation shifts of the high basin, while surveyed township lines emphasize the remote administrative management of this vast rangeland in the mid-2010s.
