Yellowstone National Park: Essential Facts, Wonders, and History
Discover the dramatic landscapes, wildlife, geysers, and fascinating history of Yellowstone — America’s first national park.
Yellowstone National Park remains one of the most iconic destinations in the world, celebrated for its vast wild landscapes, unique geology, abundant wildlife, and a history that helped shape conservation worldwide. Spanning over 2.2 million acres across three states, Yellowstone is both a sanctuary for nature and a living testament to the enduring importance of preserving natural heritage.
Overview: America’s Oldest National Park
Established in 1872, Yellowstone became the first national park in the United States and is widely considered the first in the world. This designation set a precedent for conservation and public enjoyment of wild lands globally.
- Location: Mostly in northwest Wyoming, with portions in Montana and Idaho.
- Size: 2,221,766 acres (about 3,472 square miles), making it larger than the states of Rhode Island and Delaware combined.
- Elevation: Ranges from about 5,282 to 11,358 feet (1,610 to 3,462 meters) above sea level.
- Seasons: Open year-round, with peak visitation during the summer months.
Geological and Geothermal Marvels
Yellowstone is globally famous for its extraordinary geothermal features, the result of its location atop a massive volcanic hotspot. These natural wonders offer both scientific intrigue and breathtaking beauty.
- Geysers: Over 300 active geysers—more than half of the world’s total—erupt across the park.
- Hot Springs and Mud Pots: Over 10,000 hydrothermal features include steaming fumaroles, colorful hot springs, and bubbling mud pots.
- Notable Geothermal Features:
- Old Faithful: The park’s most famous geyser erupts reliably every 60 to 110 minutes, spewing up to 8,400 gallons of water to heights reaching 180 feet. The temperature during eruptions reaches about 204°F.
- Grand Prismatic Spring: Famed for its dazzling rings of color, this is the largest hot spring in the United States.
- Norris Geyser Basin: The hottest and most volatile of Yellowstone’s hydrothermal areas, home to the extraordinary Steamboat Geyser—the world’s tallest active geyser.
- Supervolcano: The entire Yellowstone Caldera is a vast volcanic system, responsible for past cataclysmic eruptions and continuing geothermal activity.
Yellowstone’s Vast and Diverse Ecosystems
Encompassing valleys, mountains, forests, rivers, and lakes, Yellowstone boasts an incredible range of habitats, supporting a remarkable diversity of plant and animal life.
- Yellowstone Lake: The largest high-elevation lake in North America, covering about 131.7 square miles.
- Rivers: The Yellowstone River carves through the park, including the dramatic Grand Canyon of the Yellowstone.
- Forests and Grasslands: Lodgepole pine, Douglas fir, and open meadows provide habitat for many species.
Incredible Wildlife
The park is a refuge for wildlife native to the Rocky Mountains and Greater Yellowstone Ecosystem. Visitors can encounter animals rarely seen elsewhere in the continental United States.
- Mammals: 67 species, including bison, grizzly bears, black bears, gray wolves, elk, moose, pronghorn, mountain lions, and bighorn sheep.
- Birds: Approximately 285 species, with more than 150 nesting within the park. Includes bald eagles, osprey, trumpeter swans, and sandhill cranes.
- Fish: 16 species inhabit the park’s rivers and lakes, including native cutthroat trout.
- Reptiles and Amphibians: A limited number of species due to the harsh winters, but includes garter snakes, frogs, and salamanders.
Yellowstone is home to the largest wild bison herd in the United States and played a pivotal role in the successful reintroduction of gray wolves in the 1990s, restoring natural balance to the ecosystem.
