Millions of years ago, the North American continent was dragged over the world's largest continental hotspot, a huge column of hot and molten rock rising from the Earth's interior that traced a 50-mile wide, 500-mile-long path northeastward across Idaho. Generating cataclysmic volcanic eruptions and large earthquakes, the hotspot helped lift the Yellowstone Plateau to more than 7,000 feet and pushed the northern Rockies to new heights, forming unusually large glaciers to carve the landscape. It also created the jewel of the U.S. national park system: Yellowstone. Meanwhile, forces stretching apart the western U.S. created the mountainous glory of Grand Teton National Park. These two parks, with their majestic mountains, dazzling geysers, and picturesque hot springs, are windows into the Earth's interior, revealing the violent power of the dynamic processes within. Smith and Siegel offer expert guidance through this awe-inspiring terrain, bringing to life the grandeur of these geologic phenomena as they reveal the forces that have shaped--and continue to shape--the greater Yellowstone-Teton region. Over seventy illustrations--including fifty-two in full color--illuminate the breathtaking beauty of the landscape, while two final chapters provide driving tours of the parks to help visitors enjoy and understand the regions wonders. Fascinating and informative, this book affords us a striking new perspective on Earth's creative forces.

Students of conservation encounter some of the most complex issues on our planet. The resolution of existing problems become more complex when humans create further stresses on the natural balance. Moulton and Sanderson brought the challenging issues in wildlife conservation into greater clarity in Wildlife Issues in a Changing World. The Second Edition of this definitive reference focuses more closely on the causes of wildlife issues. The examination of Jared Diamond's "Evil Quartet" (the four principal causes of extinction) provides a framework for categorizing and resolving these issues. The authors encourage the use of the scientific method basis for resolution - especially where environmental laws have failed. The three new chapters provide further counterpoints to preconceived notions. A two-part history of wildlife in the U.S. shows how wildlife had already been decimated by the year 1900. "Can Humans Manage Wildlife?" questions efforts to revive endangered species, acts which may inadvertently jeopardize the survival of other life. Viewing the natural order from prehistoric times to the present, Wildlife Issues in a Changing World, Second Edition gives students and instructors an all-encompassing introduction to past relations between humans and nature; explorations of current threats to species and their habitats; and recent "novel solutions," where humanity and industry have made adjustments to protect the natural order. Professionals will also find invaluable reminders of the importance of their work - the continuation and endurance of wildlife everywhere on Earth.
