Yellowstone's geology is one-of-a-kind. The course will start with an overview of rock classification, plate tectonics and geologic time scale. The Precambrian, Paleozoic and Cenozoic depositional history and the formation of the Rocky Mountain ranges will also be covered. Other highlights include examining the Eocene volcanic activity, the preserved petrified forest, the origins of the Yellowstone hotspot, the history of mega-eruptions, the formation of the Yellowstone caldera and subsequent eruptions. Glacial deposits at Yellowstone and the hydrothermal features along with hydrothermal explosions and earthquakes will also be discussed. No prior geology required but helpful.
