Keep this tabbed booklet close at hand on your next rock-hunting adventure. Based on Dan R. Lynch's best-selling field guides and featuring the most common and desirable agates and other collectibles along the Pacific Coast, the booklet is organized by rocks/minerals and then by general appearance for quick and easy identification. With six varieties of agates, as well as popular finds like Jasper, Quartz, and even Jade, this handy guide has the information you want. Narrow your choices by appearance, and view photos of just a few specimens at a time. The easy-to-use format means you'll quickly find what you need to know. Plus, the quick guide is much easier to use than laminated foldouts, and the tear-resistant pages help to make the book durable in the field.
