These two parks are windows into the Earth's interior, revealing the violent power of the dynamic processes within. In Windows into the Earth Robert Smith and Lee Siegel offer guidance through this 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 beauty of the landscape, while two final chapters provide driving tours of the parks to help visitors enjoy and understand the regions' wonders. "I love this book not only for its ground-breaking science, but for its insight and empathy into these beloved wildlands that offer so many of us sanctuary."--Terry Tempest Williams "The terrifying birth of these glorious places of mountain vistas, geysers and hot springs is brought to life by geophysicist Smith and science writer Siegel in this magnificently illustrated book."-- Denver Rocky Mountain News "The spectacular geysers and hot springs of Yellowstone are the world's best. They are in part the remains of a gigantic volcanic explosion 630,000 years ago that was a thousand times larger than the 1980 eruptions of Mount St. Helens. They also portend future volcanic action in this beautiful wonderland. Geologist Smith and science writer Siegel team up to tell the exciting story of how Yellowstone and Grand Teton National Parks came to be."--Bob Decker is Professor Emeritus at Dartmouth College and Barbara Decker is a science writer "Only a tiny percentage of the 3.1 million people visiting Yellowstone National Park each year have the foggiest notion that they have driven into the maw of one of the greatest volcanic systems on Earth. Bubbling mudpots and jetting geysers provide clues that a vast reservoir of heat lies at shallow depth, but one might well ask, 'Where's the volcano?' Bob Smith and Lee Siegel answer this question and many, many more. In guiding readers through this geologic wonderland, they explain both hot spots and heat flow, and how thousands of huge earthquakes in the recent geologic past accompanied the rise of the magnificent Teton Range just to the south. Those who believe Earth to be an inactive place are in for a rude awakening here!"--Richard S. Fiske, Geologist and former Director of the Smithsonian Institution's National Museum of Natural History A beautifully illustrated account of the geological evolution of our two most awe-inspiring national parks Robert B. Smith is a professor of geology and geophysics at the University of Utah and a fellow of the American Geophysical Union and the Geological Society of America. Used Book in Good Condition
