About this map

Fiddlers Green and Alder Springs occupy a remote section of Glenn County within the Mendocino National Forest. This landscape is defined by the sharp vertical relief between ridges and deep drainage canyons, where named water sources like McGrew Spring, Doe Spring, and Hard Spring suggest the importance of reliable water in the high country. The road network, including Forest Highway Seven and several county roads like Glenn Co Road (Sanhedrin), traces the complex topography of Rattlesnake Ridge and Hardin Hole Ridge.

Evidence of historical land use is seen at Grassy Patch and Alder Flat, areas where the terrain levels off enough to support small mountain meadows. The presence of Forks Reservoir along the eastern edge indicates water management in a region otherwise dominated by seasonal creeks such as Grindstone Cr and Rattlesnake Cr. These features highlight the dual nature of the area as both a timber resource and a critical watershed.
