Preserved within Yellowstone National Park are Old Faithful and the majority of the world's geysers and hot springs. An outstanding mountain wildland with clean water and air, Yellowstone is home of the grizzly bear and wolf and free-ranging herds of bison and elk. Centuries-old sites and historic buildings that reflect the unique heritage of America's first national park are also protected. Yellowstone National Park serves as a model and inspiration for national parks throughout the world.
We are the stewards of your park and we are charged with protecting its priceless resources and ensuring they remain unimpaired for future generations. The people who work and volunteer here enjoy sharing the park with visitors, as it allows them to see it fresh through your eyes. Please, seek us out! Step inside a visitor center or attend a ranger walk. Our administration offices are at Mammoth Hot Springs and we have staff and offices in all of the developed areas throughout the park.
