California Gold & Gems Maps, Northern Edition is a comprehensive collection to assist the rockhound in locating 40 gem sites. The source of information has been taken from numerous publications. All known types of rock and gem deposits could not be included because of the numerous types and locations would be overwhelming. Some of the reported gold and gold districts are included as far back as 1850.
The first report of gold in California was published in Spain in 1510. California was believed to be an island north of Mexico where gold and precious stones were abundant. Gold was actually mined in California as early as the late 18th century but the "rush" did not begin until the discovery at Sutters Mill in 1848.
Rock and Gem collecting in California is virtually unlimited as illustrated by the key symbols on each USGS map section. A few counties that host exciting deposits are as follows: Siskiyou, Trinity, Tehama and Plumas.
The early maps included in this publication were located in various archival collections. The primary sources were the National Archives and the California State Library. The U.S. Geological Survey supplied the featured modern map. The design is planietric for clarity.

Heavy duty 3/4'' plain black nylon loupe lanyard with a quick release buckle and a split ring. This lanyard may be used for any purpose but we've had it custom manufactured specifically for use with the BelOMO loupe.
Important: We offer this lanyard for no additional charge when you buy the combo package of the BelOMO loupe with attached lanyard. Attaching the lanyard requires a screw to be removed so let us do it. We've been doing it for years and you save money!
Use the split ring on loupes with a mounting hook. To use the lanyard with a BelOMO loupe remove one screw on the support shaft of your BelOMO loupe, swivel the frame out of the way and slide the end over the support shaft then install the screw again. Don't use the split ring to attach the lanyard to the loupe. (We suggest that you purchase the loupe with the lanyard already installed.)
