Yellowstone National Park was established as the world's first national park on March 1, 1872. It stretches into three states: Wyoming, Montana, and Idaho, encompassing nearly 3,500 miles. Yellowstone is larger than the states of Delaware and Rhode Island combined.
Yellowstone experiences 1,000 to 3,000 earthquakes annually and is home to 300 active geysers and nearly as many waterfalls. Two endangered species, the Canada lynx and the grizzly bear, call the park home. Over four million people travel to Yellowstone National Park every year.
The park is known for the Old Faithful geyser, which erupts every 92 minutes. It was the first geyser in the park to be named and received its iconic moniker in 1870. Each eruption lasts one to five minutes and releases around 3,700 to 8,400 gallons of water. If you visit Old Faithful, stay away from the water; eruption temperatures can reach as high as 204°F!
