Site of the Day for Thursday, August 8, 2002 Rocking the Parks: Geological Stories of the National Parks The List presents an offering which is not so much a site as a textbook. Gentle members planning a foray into one of the major U.S. national parks during their summer holidays may wish to delve into the exciting geological facets of various parks. This site contains the text for the course "Geosciences 10: Geology of the National Parks" from Penn State geology professor Dr. Richard B. Alley. Among the goals of the course are "to help you become better-informed . . . on topics that may affect you in the future (groundwater pollution, biodiversity, volcanic hazards, etc.); to demonstrate what is and is not believable about science . . . to give you enough geological background that you will get more out of your next visit to a park; and to show you enough beautiful places that you can't wait to go out and visit some of them." - from the website This online text presented in Adobe Acrobat format covers such riveting topics as 'Extinction and Dinosaur National Park -- What killed the dinosaurs?', 'Island Biogeography --Yellowstone and the Next Mass Extinction', 'Glaciers and Glacier National Park -- Flowing solids and hot ice', 'Weather and Climate in the Redwoods -- Why the wind blows, why the wind spins, heating Death Valley' and 'Plate Tectonics I -- Death Valley is Growing Wider' among others.
