Description: 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.
