Experience America’s first national park online. Explore Yellowstone National Park’s most popular questions and important issues with park rangers, scientists, historians and park visitors. What have we discovered about Yellowstone’s wildlife, geysers and other natural wonders? How can we learn from the park’s history in order to protect its future? This educational video series takes an in-depth look at such topics as its wild animals (including bears, wolves, bison, and fish), the geological and ecological processes that shape the park (including fire and the Yellowstone volcano), and its human history. We also invite you to take a virtual tour of the park through the related video series, “Inside Yellowstone,” located in "Society & Culture" in the “Places & Travel” category.
