With more than 10,000 geysers, hot springs, fumaroles, and mud pots, as well as cubic mile upon cubic mile of once-incendiary rhyolite, the landscape of Yellowstone Country vividly displays its fiery past and present.
The region contains 1/5 of the world�s geysers, including the most famous of them all, and is the setting of some of Earth�s most destructive volcanic eruptions.
The 19 road guides in Roadside Geology of Yellowstone Country fully explore this volcanic pedigree while also delivering you to sites that have recorded the region�s broad and deep geologic story, which includes exquisitely preserved, 50-million-year-old petrified trees buried in conglomerate; mountain-sized blocks of rock that slid more than 50 miles in a massive debris avalanche; the glacially carved craggy peaks and U-shaped valleys of the Beartooth Mountains and Absaroka Range; and the Grand Canyon of the Yellowstone, the excavation of which is still a mystery.
This completely revised second edition reexamines the region using the latest scientific thinking and now includes stunning full-color photos, maps, and diagrams.
