About this map

Stonyford sits at the southern edge of this 1968 landscape, serving as a gateway to the diverse terrain of the Mendocino National Forest. The geography is defined by a series of prominent ridges, including Gravelly Ridge, Green Valley Ridge, and the distinctive Black Diamond Ridge. These elevations are cut by significant waterways like Stony Creek and Little Stony Creek, which helped shape the grazing and small-scale mining activity of the area.

Evidence of local development and resource extraction is found in the Indian Valley School and various prospects and mines scattered across the hills. High points such as Goat Rock and Sugarloaf Hill provided vantage points for fire suppression, most notably at the Lookout Tower (No. 3). The map also details unique natural features like Sulphur Spring and Salt Spring within Salt Spring Valley, illustrating the specific geological character of the Glenn and Colusa County border region.
