Yellowstone National Park – wildlife, photos, lakes, waterfalls, hikes, etc

Yellowstone National Park is one of the most visited National parks in the United States. Spread over an area of 2,219,789 acres, the national park is famous for its wildlife, geysers, hot springs, and other hydrothermal systems.

The vast area of the National Park falls in the states of Wyoming, Montana, and Idaho, majorly in Wyoming. The park is even larger than Rhode Island and Delaware states of the US. Established on March 1, 1872, Yellowstone National Park is perhaps the oldest National Park in the world. It is designated as a UNESCO World Heritage Site.

In northwest Wyoming inside the National park, lies the largest volcanic system in North America – the Yellowstone supervolcano. The supervolcano last erupted about 640,000 years ago. Most scientists classify this supervolcano as dormant but you never know. The ground above the volcano swells and falls depending on the activity in the magma chamber. The magma chamber lies 4-6 miles (6-10 kilometers) beneath.
