1989 Map of Benmore Canyon

About this map

The Indian Valley Reservoir dominates the northeastern landscape of this Lake County quadrangle, where the impounded waters meet the steep ridges of the Mendocino National Forest. The map documents a rugged interior terrain shaped by the North Fork Cache Creek and its many tributaries, including Wolf Creek and Salt Creek. This area's geological and industrial character is evident through the presence of the Chalk Mountain Mine near the summit of Chalk Mountain, alongside scattered resource extraction sites like a Quarry and Gravel Pit.
