About this map

Sanhedrin Mtn Big Signal Peak and Little Signal Peak dominate the topography of this section of the Mendocino National Forest, where the border between Mendocino and Lake counties follows the high ridgelines. The landscape is defined by a series of steep drainages, including Elk Cr, Sanhedrin Cr, and Bear Cr, which carve through the elevations near Thatcher Butte. Small highland water bodies such as Lily Pad Lake and Tule Lake provide distinct landmarks in a terrain characterized by natural clearings like Sportsman Glade and Cow Flat.

A network of Forest Service roads, including 19n72 and 20n08, provides access to these peaks and remote basins. The presence of named features like Impassable Rock and Bennett Valley suggests a history of difficult navigation and early land use within the forest. Notable for researchers is the detail of natural springs and small flats that often served as early camps or landmarks for those traversing the mountains before modern improvements.
