Yellowstone's not only the second-largest national park in the continental U.S.-it's many lakes, canyons, rivers, and mountain ranges are also home to a variety of wildlife, including several endangered species. Of these, the gray wolf's documented re-introduction makes a rare and inspiring story, highlighting the need for conservation of one the world's most precious ecosystems.
