It presents the important traditional content of mineralogy including crystallography, chemical bonding, controls on mineral structure, mineral stability, and crystal growth to provide a foundation that enables students to understand the nature and occurrence of minerals. Physical, optical, and X-ray powder diffraction techniques of mineral study are described in detail, and common chemical analytical methods are outlined as well. Detailed descriptions of over 100 common minerals are provided, and the geologic context within which these minerals occur is emphasized. Appendices provide tables and diagrams to help students with mineral identification, using both physical and optical properties. Numerous line drawings, photographs, and photomicrographs help make complex concepts understandable. Introduction to Mineralogy not only provides specific knowledge about minerals but also helps students develop the intellectual tools essential for a solid, scientific education. This comprehensive text is useful for undergraduate students in a wide range of mineralogy courses.

    Advice, with photographs, from an expert!Novices eager to collect tasty wild mushrooms will find this unique guide invaluable.

The ninth edition of The Colorado Trail has all the information a day hiker, thru-hiker, mountain biker, or equestrian needs to plan and complete a trip on the trail. New to this edition are five chapters on the 80-mile Collegiate West trail addition. Maps and written descriptions for all twenty-eight segments of the Colorado Trail have also been updated throughout the guide. Each chapter provides essential logistical information for Colorado Trail hikers: trailhead directions; road access points; detailed trail descriptions including distance and elevation gain; color maps and elevation profiles; and information on water sources, campsite locations, and resupply towns. Additional town maps and mountain bike detour maps (around Wilderness Areas) have been included throughout the book. An extensive introduction includes information on planning, supplying, safety, equipment, navigation, mountain biking, horseback riding, regulations, and backcountry ethics—plus chapters on the heritage of The Colorado Trail, natural history, and geology. At the back of the book you will find useful contact information and an index.

    Clear instructions, diagrams, and photographs show how to build projects ranging from the simple—a match-powered rocket—to the more complex—a scale-model, table-top catapult—to the offbeat—a tennis ball cannon. With a strong emphasis on safety, the book also gives tips on troubleshooting, explains the physics behind the projects, and profiles scientists and extraordinary experimenters such as Alfred Nobel, Robert Goddard, and Isaac Newton. This book will be indispensable for the legions of backyard toy-rocket launchers and fireworks fanatics who wish every day was the fourth of July.

    Darwin wondered why these birds were confined to remote islands at the tip of South America, sensing a larger story, but he set this mystery aside and never returned to it. Almost two hundred years later, Jonathan Meiburg takes up this chase. He takes us through South America, from the fog-bound coasts of Tierra del Fuego to the tropical forests of Guyana, in search of these birds: striated caracaras, which still exist, though they're very rare. He reveals the wild, fascinating story of their history, origins, and possible futures. And along the way, he draws us into the life and work of William Henry Hudson, the Victorian writer and naturalist who championed caracaras as an unsung wonder of the natural world, and to falconry parks in the English countryside, where captive caracaras perform incredible feats of memory and problem-solving. A Most Remarkable Creature is a hybrid of science writing, travelogue, and biography, as generous and accessible as it is sophisticated, and absolutely riveting.

    For three men in particular, 1998 would become a grueling battle for a new North American birding record. Bouncing from coast to coast on frenetic pilgrimages for once-in-a-lifetime rarities, they brave broiling deserts, bug-infested swamps, and some of the lumpiest motel mattresses known to man. This unprecedented year of beat-the-clock adventures ultimately leads one man to a record so gigantic that it is unlikely ever to be bested. Here, prize-winning journalist Mark Obmascik creates a dazzling, fun narrative of the 275,000-mile odyssey of these three obsessives as they fight to win the greatest -- or maybe worst -- birding contest of all time.
