Introduction Yellowstone’s Hayden Valley has been shaped by volcanism, ice, and water. Its unique geologic history has created a variety of habitats that provide for a rich diversity of plant and animal life. Join a crew of alien visitors as they zoom in on Hayden Valley to explore the unique geology and ecosystems found here. Dive under the Earth’s surface for a lesson on hotspots; then emerge to follow bears, bison, elk, wolves, and other creatures through a Hayden Valley year. The Ask an Expert Message Board is available from November 12-14, 2003. Resource Experts will be available to answer your students' questions. The questions and answers will remain accessible after the message board has been deactivated. You may want to view the Park’s Orientation program before taking this electronic field trip.
