Yellowstone National Park

A land of fire and water, Yellowstone preserves the world’s greatest concentration of geysers atop a living supervolcano—where wildlife, geology, and history converge.

History of the Park

Yellowstone National Park sits atop a massive volcanic system that has shaped the region for millions of years. Three major volcanic eruptions—occurring roughly 2.1 million, 1.3 million, and 640,000 years ago—created the Yellowstone Caldera. Heat from this system fuels the park’s famous geysers, hot springs, fumaroles, and mud pots, making Yellowstone the most geothermally active place on Earth.

Human presence in Yellowstone dates back at least 11,000 years. Indigenous tribes including the Shoshone, Bannock, Crow, Blackfeet, and others traveled through the region to hunt, gather, and trade. The park’s name itself is believed to derive from Indigenous descriptions of the river flowing through yellow-hued canyon walls.

In 1872, Yellowstone became the world’s first national park, established by President Ulysses S. Grant. This unprecedented act set aside the land “for the benefit and enjoyment of the people,” creating a model for conservation that would later spread across the globe.

Park Culture

Learn about the local culture surrounding this park.

Yellowstone’s cultural significance extends far beyond its borders. As the birthplace of the national park idea, it represents a global shift in how humans value and protect wild places. Early expeditions, artists, and photographers helped capture the park’s wonders, shaping public support for conservation.

The park’s landscape is extraordinarily diverse—rolling plateaus, deep canyons, vast forests, alpine rivers, and expansive grasslands. Yellowstone supports one of the last largely intact temperate ecosystems on Earth, home to free-roaming bison, wolves, elk, and grizzly bears.

Yellowstone is both ancient and alive. Its steaming basins and roaming wildlife serve as constant reminders that the Earth beneath our feet is active—and that preserving such power and beauty requires humility, stewardship, and restraint.
