About this map

Lake Davis dominates the central landscape of this portion of the Plumas National Forest, serving as a focal point for the surrounding high-elevation terrain. The map illustrates a complex network of forest roads and spurs, such as the Old House Grade and Happy Valley Spur A, which navigate the steep rises of Mt Ingalls and Grizzly Ridge. These routes provide access to named landmarks like Threemile Rock and Lightning Tree Point on the lake's eastern shore.

Water systems define the valleys, with Big Grizzly Cr feeding into the lake while Red Clover Cr flows through the northern reaches of Red Clover Valley. The arrangement of features like Gate Place Spring and the Tramway Spur suggests a landscape managed for both resource extraction and recreation. Notable geographic points such as Bagley Pass and Turner Ridge provide natural corridors through the varied topography of this Plumas County region.
