Rocks &; Minerals of the United States

Keep this tabbed booklet close at hand on your next rock-hunting adventure. Based on Dan and Bob Lynch's best-selling field guides and featuring 60 of the most common rocks and minerals in the country, the booklet is organized by rocks/minerals and then by general appearance for quick and easy identification. Narrow your choices by appearance, and view just a few specimens at a time. The pocket-sized format is much easier to use than laminated foldouts, and the tear-resistant pages help to make the book durable in the field.
