About this map

The Eel River winds through the northern reaches of this Mendocino County landscape, designated here as a National Wild and Scenic River. This 1991 survey shows a terrain dominated by the Mendocino National Forest and the heights of Foster Mountain. Settlement patterns are sparse, marked by the Hearst (Site) and the Emandal Resort near the riverbanks.

Evidence of historical land use and natural resources appears in the southern portion of the map, where the Potter Valley Rancheria Indian Reservation is located. The map records several natural and industrial markers, including a Mine, the waters of Lake Lee, and Soda Spring. Extensive drainage networks like Tomki Creek and Long Branch Creek define the ridges and canyons, providing a detailed look at the hydrology of the California Coast Ranges during the late twentieth century.
