2018 Map of Ash Valley

About this map

Ash Valley defines the central topography of this northeastern California landscape, where high-altitude wetlands and seasonal drainages converge. The 2018 survey reveals a landscape largely shaped by ranching and public land management, with the southwestern corner falling within the Modoc National Forest. Transportation is defined by a network of ranch and access roads, including Ash Valley Rd and the specifically named P Bar T Ranch Rd, which navigate the elevation changes between Knox Mtn and Anderson Mtn. Water remains the most critical resource for this high desert environment, evidenced by the strategic locations of Fleming Spring, Diaz Spring, and Fulstone Spring. These water sources and the surrounding terrain of Sagebrush Flat illustrate the enduring utility of the land for grazing and watershed protection.
