About this map

Mendocino National Forest encompasses this high-elevation terrain along the border of Mendocino and Lake Counties. The landscape is dominated by the massive ridge systems of Sanhedrin Mountain, culminating at Big Signal Peak and Little Signal Peak. The topography is defined by steep drainage basins feeding numerous watercourses, including Deep Hole Creek and Ellis Creek, which carve through the elevations toward Bennett Valley.

Human presence is limited to scattered clearings and named flats that suggest a history of seasonal use and grazing. Small mountain waters like Lily Pad Lake and Summit Lake are tucked into the high contours, while the lower elevations are accessed via Eden Valley Ranch Road. Named landmarks such as Sportsman Glade and Four Pines provide critical navigational points in this complex network of ridges and drainages.
