About this map

Mendocino National Forest encompasses this high-elevation landscape in Tehama County, where a network of ridgelines and creek forks once supported seasonal camps and small-scale mining. The topography is dominated by massive features like Riley Ridge, Tatham Ridge, and Trough Ridge, which channeled early movement through the forest. Human presence is marked by isolated cabins and named family homesteads, such as Mitchell Place, Steuben Place, and Dawson Place.

Resource extraction and fire management are central themes on this sheet, evidenced by the South Elder Mine near Brush Mtn and the Kleinsorge Mine to the north. These sites, along with the Eagle Rock Lookout Tower atop Eagle Peak, reveal how this remote backcountry was utilized and protected in the late 1960s. High-country drainage is intricately mapped, following the South Fork Elder Creek and Middle Fork Elder Creek as they cut through the steep terrain.
