Mendocino National Forest dominates this Colusa County landscape, where the steep terrain of Gilmore Ridge and Sullivan Ridge gives way to the open waters of the East Park Reservoir. The map illustrates a transitional zone between the high ridges of Gilmore Peak and the agricultural lands of Indian Valley. In the lower elevations, the human presence is marked by infrastructure like the Diversion Dam and Gaging Station on Stony Creek.
