From the mountains to the ocean shores, from the wetlands to the deserts, North America teems with flora and fauna in delicately balanced ecosystems found nowhere else on Earth. With this book in hand, you will understand the language of nature and see those wild places with new eyes. You'll learn to recognize the lobed leaf of an Oracle Oak, the webbed tracks of a River Otter, and the fine, cream-colored tentacles of a Frilled Anemone. This volume celebrates a tradition of knowledge established by the Nature Study Guild. For more than sixty years, the Guild's pocket guidebooks have helped hikers, campers, foragers, and explorers navigate the great outdoors. Now, the best of the guides' informative text and iconic illustrations are gathered in one handsome hardcover: the perfect reference for today's ramblers.
