Within the park's massive boundaries, visitors can find mountains, rivers, lakes, waterfalls and some of the most concentrated geothermal activity in the world. The park has 60% of the world’s geysers, as well as hot springs and mud pots. It is also home to diverse wildlife with the largest concentration of mammals in the Lower 48 states, including grizzly bears, wolves, bison and elk.

Despite being the fastest land mammal in the Western Hemisphere, pronghorn are not built to jump. Fences in their historic migration pathways caused the pronghorn population in Yellowstone to plummet. By 2004, park biologists estimated that fewer than 200 remained in the northern herd. The small herd was extremely susceptible to disease and severe weather threatening the long-term survival of this population.
