About this map

Grizzly Flats serves as a primary point of interest in this El Dorado County landscape, situated within the Eldorado National Forest. The geography is defined by a complex network of waterways, including the N Fork Cosumnes River, the Steely Fork Cosumnes River, and Sly Park Cr, which feeds into the prominent Jenkinson Lake. This reservoir is surrounded by distinctive terrain features such as Bumpy Meadows and Fleming Meadow, reflecting the recreational and water-management character of the region.

Legacy resource extraction is evident through several noted sites, including the Blue Gouge Mine, Cosumnes Mine, and Eagle Mine, pointing to a history of prospecting in the foothills. The presence of the Crawford Ditch and Butte Creek further illustrates the historic movement of water through the ridges. Small settlements like Post Flat and Happy Valley are reached via a winding network of forest roads such as Old Sly Park Road and Silver Lake Road.
