Mendocino National Forest defines this high-elevation landscape in Tehama County, where a network of prominent ridges and drainages shape the terrain. The central spine of Raglin Ridge and the western flank of Elkhorn Ridge create a series of isolated basins, including Bear Wallow and Sunflower Flat. These higher elevations are punctuated by numerous natural water sources critical for the region's cattle and timber history, such as Sulphur Spring, Bear-Wallow Spring, and Salt Lick Spring. Navigation across these folds relies on historic routes like Colyer Springs Rd and Raglin Ridge Rd, which trace the contours of Whisky Ridge and Valentine Ridge. The map details a complex system of seasonal and perennial creeks, including N Fork Elder Cr and S Fork Cottonwood Cr, which have historically dictated access and use in this section of the national forest.
