By Gail A. Butler (Author) Although known for its gold production, California is a virtual haven for rock and gem collectors. Explore the mineral-rich desert regions, comb tide-washed beaches for jade, agate, abalone, and fossilized whale bone, and prospect in the mountains and hills for gold, copper and other minerals and gems. The Rockhound’s Guide to California describes 75 of the state’s best rockhounding sites, and covers the popular and commercial sites as well as numerous little-known areas. This handy guide describes how to collect specimens, includes maps and directions to each site, and lists rockhound clubs around the state.
