Celebrate Yellowstone’s 150 Years as a National Park

Discover the milestones of the world's first national park and participate in celebrations.

Yellowstone turned 150 years old March, 1, 2022, which is an incredible milestone. When Yellowstone became a national park, it was the first of its kind in the world. The notion of setting aside wild land to protect it from development was alien to a lot of Americans back then. At the time, progress was often measured by how many towns and cities we could carve out of the land, land that was more often than not already occupied by Native American tribes and thousands of species of animals. Because of a lot of park rangers, legislators, policies and citizens, Yellowstone is just as unique as it was when it was founded. Thanks to these efforts, some of the park’s animal populations are healthier than they were at the turn-of-the-century and the park has been working with Native tribes who have roots in Yellowstone to discuss ways in which the tribes can play larger roles in the park.

“We’re proud to commemorate the 150th anniversary of Yellowstone with America,” says Yellowstone Superintendent Cam Sholly. “This anniversary should remind us of the incredible value of our National Park System and the need for us to continue working together to address the many challenges of the future.”

Here are some of the park’s many milestones that cover the highs and lows of its 150 years from 1872 to 2022.

1872 Yellowstone becomes the world’s first national park
1883 The railroad arrives in the park.
1886 The U.S. Cavalry patrols the park to discourage the 27 tribes associated with Yellowstone from hunting and gathering within park borders. This continues for 32 years.
1904 The Old Faithful Inn opens with electric lighting.
1915 Park managers allow automobiles into the park.
1916 The nation’s last remaining wild herd of 23 bison find refuge in Pelican Valley in Yellowstone. Park managers begin some of the nation’s first efforts to save an endangered species.
1925 Marguerite Lindsley, a bacteriologist, becomes the first permanent female park ranger.
1966 Thomas Brock, a microbiology professor vacationing in Yellowstone, becomes intrigued by the microbes living in the park’s hot pools. His research leads to the discovery that extreme environments like scalding hot pools can support life.
1970 Open-pit garbage dumps are eliminated, ending the nightly “bear shows” where visitors watched black and grizzly bears eat garbage from wooden bleachers.
1988 Yellowstone gets ravaged by wildfires, which burn about 36% of the park.
1993 Kary Mullis wins the Nobel Prize in chemistry for his invention of Polymerase Chain Reaction (PCR). Critical to his work was microbe species Thermus aquaticus from Yellowstone. PCR is used to detect disease and identify DNA left at crime scenes
1995 Fourteen gray wolves from Canada are released in Yellowstone, leading to the park’s first wolf pack in 69 years.
2019 Excess Yellowstone bison that are disease-free are transported to the Assiniboine and Sioux tribes of Fort Peck, Mont., to restore tribal bison populations. This continues today.
2020 The PCR test, with roots in Yellowstone, plays a key role in detecting the virus that causes COVID-19.
2021 Hunters kill 20 wolves that roam outside of the park, exterminating most or all of the park’s Phantom Lake Pack. Ninety Yellowstone wolves are left as of Feb. 2, 2022.
2022 Yellowstone turns 150 years old.
