People come to Yellowstone primarily because of the unusual thermal features and opportunities to view wildlife, often not realizing they are standing on one of the world's largest active volcanoes. This film presents an interpretation of the sweeping geologic story of Yellowstone, from glaciation to mountain-building to the gigantic caldera of a volcano. "Yellowstone: Land to Life" was filmed over two years in all four seasons and delves deeply into the significance behind the scenery. It also explores the bonds between the landscape and biology -- how Yellowstone's geology influences where life exists and how it evolves. The film also contemplates our connection as well: humankind's relationship to Yellowstone, the world's first and most famous national park.
