Windows into the Earth: The Geologic Story of Yellowstone and Grand Teton National Parks
by Robert B. Smith and Lee J. Siegel
From the Publisher: 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. Smith and Siegel bring 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.
