The Treasure Hunter's Gem & Mineral Guides to the U.S.A.: Northwest states

Whether you're digging for the first time or are an experienced rockhound or 'prospector', with a simple rock hammer and a little luck, you too can strike it rich... or at the very least, have fun trying. This guide offers you easy to use information on the ins and outs of 'fee dig' mining, complete with locations, costs, tips on technique, entertaining legends and important information on everything from safety kits to the location of the nearest restrooms. Included are resources for use in identifying your finds, having them made into jewellery, and further pursuing an exciting -- and possibly profitable -- hobby.
