Timeline: 144 Years of Yellowstone
Did you know that Yellowstone became the world’s first national park in 1872? In the past 144 years, some things have changed at Yellowstone National Park, while other things remain largely the same! Here’s an at-a-glance look at the history of Yellowstone since its inception, with some key dates and happenings highlighted along the way.
March 1, 1872: President Ulysses S. Grant signs the Yellowstone National Park Protection Act, officially designating Yellowstone the world’s first national park.
Late 1870s: The U.S. Congress approves measures to “protect, preserve, and improve the Park.” Superintendent Philetus W. Norris oversees the construction of roads and of a park headquarters at Mammoth Hot Springs. Today’s Grand Loop Road follows much of Norris’ original road system.
1886: Due to issues with poaching, vandalism, and other crimes, the U.S. Army takes over the supervision of Yellowstone, guarding major attractions and enforcing regulations throughout the park as well as patrolling the interior.
1891: Lake Hotel is built. The iconic columns and extended gables were added in 1903-04, and the hotel is further renovated in the 1920’s to add a port cochere, Sun Room, East Wing of guest rooms, and other interior features. In 2013-14, a major structural and interior renovation is completed and Lake Hotel received National Historic Landmark designation in 2015.
Late 1800s: Development of the Mammoth Hot Springs area is developed, including the Mammoth Post Office and, in 1903, the Roosevelt Arch, located approximately five miles north of Mammoth in Gardiner, MT.
1904: The Old Faithful Inn is completed, which was designed to complement the natural setting around the building and becomes a significant inspiration for rustic architecture. In 1987, it is designated a National Historic Landmark.
1916: The National Park Service Organic Act is passed by Congress and approved by President Woodrow Wilson. Yellowstone’s first park rangers are appointed in 1918 and become responsible for management of the park. Reference:
1920: The Roosevelt Lodge is constructed. It replaced a tent camp where that was originally known as Camp Roosevelt. The accommodations today remain rustic, with most cabins heated by wood stove, but is also one of the most popular lodges in the park.
1929: The park’s boundaries are adjusted to include a region of petrified trees in the northwest corner and the watershed of Pebble Creek in the northeast corner. The eastern boundary now includes the headwaters of the Lamar River and part of the Yellowstone River’s watershed. In 1932, an additional 7,000 acres between the north boundary and the Yellowstone River are added, to provide a protected winter range for wildlife such as elk and deer.
1940s: During World War II, park activity declines sharply as employees, visitors, and money for national parks are all redirected to the war efforts. Once the war ended, visitation jumped again, reaching one million visitors in 1948.
1955: The years of neglect during the war are apparent – visitors complain about poor facilities and infrastructure. National Park Service Director Conrad Wirth develops a plan for an improvement program called Mission 66 to improve the park in time for the National Park Service’s 50th anniversary in 1966. New buildings are constructed and Yellowstone, along with many other national parks, is revitalized. Mission 66’s first project in Yellowstone, Canyon Village, opens in July 1957.
1970s: A number of acts are introduced and passed by Congress to help protect the environment. These include the National Environmental Policy Act and the Clean Air Act (1970), the Clean Water Act (1972), and the Endangered Species Act (1973).
1988: More than 50 wildfires ultimately burn into five massive fire complexes that impact 793,880 acres in Yellowstone National Park – a full 36 percent of the park’s area. The largest, the North Fork Fire, burned more than 410,000 acres. The cause of the North Fork Fire was a discarded cigarette.
1995 and 1996: Wolves are reintroduced to Yellowstone National Park. During the late 1800s and early 1900s, wolves were identified as predatory animals and were routinely killed, and in 1923 the last pack of wolves had been eliminated from the park. The restoration begins with 31 gray wolves from western Canada in 1995 and 1996. An additional 10 wolves are brought in from northwest Montana in 1997. The wolf population continues to be carefully monitored, and in 2012, wolves were delisted from the endangered species list.
2007: Grizzly bears, which have been on the endangered species list since 1975, are removed from the federal threatened species list. Sadly, they return to the list just two years later, in 2009.
