As the world's first national park, Yellowstone did not come with a rule book or a manual on how national parks should be run. Things didn't always go well, but we continue to learn and improve the ways we preserve this amazing place.

  • In the early days of the park, bears could be fed along roadsides and at garbage dumps. Today, bears in the park find natural food and are wild.
  • Opened in 1914, the Geyser Baths Bathhouse was a swimming pool at Old Faithful. Today, we understand how easily hydrothermal systems can be damaged and destroyed.
  • Until the early 1900s, all predators were routinely killed in Yellowstone. Today, predators are valued as an important part of Yellowstone's ecosystem.

To preserve Yellowstone, we must all be good stewards. Stewardship means making a difference in our world and trying to make it a better place. Yellowstone's park rangers were once kids, just like you, and have dedicated their lives to protecting special places like Yellowstone.

The National Park Service Arrowhead

The arrowhead is the symbol of the National Park Service and what it protects. It is a reminder of the nature and culture national parks protect.

Take a look at the arrowhead, then take a look at what each part of the arrowhead represents.
