Kappele, a rockhound, fossil collector, gem hunter, and author of other rockhounding guides, provides a guide for those interested in collecting rocks, minerals, fossils, and gems in Nevada. He lists 105 sites for finding agate, opal, jasper, fluorescent minerals, obsidian, chalcedony, wonderstone, malachite, petrified wood, limb casts, and other rocks, with maps and information on landmarks, type of vehicle needed to get to the site, elevation, best season, land managers, tools, special attractions, accommodations, safety tips, etiquette, and sites where rockhounding is prohibited. Some b&w photos are included. This edition adds new sites and GPS coordinates for locations and removes sites that are closed to collecting.
