Yellowstone National Park is located in the northwest corner of Wyoming, with small portions extending into Montana and Idaho. It was established on March 1, 1872, through a congressional act signed into law by President Ulysses S. Grant, making it the world's first national park.

The park encompasses an area larger than Corsica and slightly below Cyprus, covering over 3,472 square miles of diverse landscapes. Yellowstone is renowned for its unique wildlife and numerous geothermal features, particularly Old Faithful, one of the most famous and picturesque geyser in the world. The subalpine forest biome dominates the park's ecosystem, with a vast array of habitats supporting an incredible diversity of flora and fauna.

As part of the Greater Yellowstone Ecosystem, the park is considered the largest remaining almost intact ecosystem in Earth's northern temperate zone. This region has been home to Native American tribes for at least 1,000 years before European exploration began in the late 1860s. The area was initially managed by the United States Department of Interior, with Columbus Delano as its first Secretary of Interior, overseeing the park from 1872.

In 1886, the U.S. Army took over management for thirty years until 1917, when the National Park Service (NPS) assumed responsibility. Since then, numerous structures have been built within the park, many of which hold historical and architectural significance. The NPS has also led archaeological research at Yellowstone, examining over a thousand sites of interest.

Yellowstone Lake is one of North America's largest high-elevation lakes, covering part of the Yellowstone Caldera, the continent's largest super volcano. Lava flows from volcanic eruptions cover much of the park's land area, and geothermal features like hot springs and fumaroles are common throughout. The park has been recognized as a UNESCO World Heritage Site since 1978, with hundreds of species documented within its boundaries, including several endangered or threatened species.

The park's diverse landscapes include canyons, rivers, mountain chains, and numerous geological formations, making it an unparalleled natural wonder in the United States.
