Rock Climbs of Placerville, CA
William H. Cottrell (2003) El Dorado Publishing ISBN 1-891119-03-6
This excellent book describes two areas around Placerville, and is by far the best resource for both areas covered. Excellent overhead views and detailed topos leave little desired, except more pictures perhaps?
Covers two areas: Cosumnes River Gorge and Mosquito Coast.
