The World's First National Park
Yellowstone was established as the world's first national park on March 1, 1872, by President Ulysses S. Grant. This pioneering move set the precedent for the preservation of natural wonders worldwide.

The Yellowstone Supervolcano
Beneath Yellowstone lies one of the world’s largest active volcanic systems. The Yellowstone Caldera, also known as the Yellowstone Supervolcano, has erupted three times in the last 2.1 million years. The last major eruption was about 640,000 years ago.

Old Faithful’s Punctuality
Old Faithful geyser, one of Yellowstone's most famous attractions, erupts approximately every 90 minutes. Despite its name, the interval between eruptions can range from 60 to 110 minutes, making it not entirely "faithful."

Over 10,000 Thermal Features
Yellowstone is home to more than 10,000 thermal features, including hot springs, mudpots, fumaroles, and geysers. This accounts for about half of the world's geothermal features!

Rainbow Colored Hot Springs
The vibrant colors of Yellowstone’s hot springs, such as the Grand Prismatic Spring, are due to thermophilic (heat-loving) bacteria. These microbes thrive in the extreme conditions, creating stunning arrays of reds, oranges, yellows, greens, and blues.

The Yellowstone Wolf Project
Wolves were reintroduced to Yellowstone in 1995 after being absent for nearly 70 years. This reintroduction has had profound ecological impacts, helping to balance the populations of other species like elk and beavers, showcasing the importance of apex predators in an ecosystem.

The Petrified Trees
Yellowstone has entire forests of petrified trees, created by volcanic ash flows from ancient eruptions. These trees have turned to stone over millions of years and provide a unique glimpse into the park's prehistoric past.

Bison Traffic Jams
Yellowstone is the only place in the United States where bison have lived continuously since prehistoric times. Today, visitors might encounter bison jams, where these massive animals wander onto the roads, causing traffic to halt as they leisurely pass by.

Microbial Mats
The park's hot springs are home to microbial mats, which are some of the oldest forms of life on Earth. These mats provide a glimpse into early life on our planet and are subjects of scientific research on extremophiles (organisms that thrive in extreme environments).

Yellowstone Lake’s Secrets
Yellowstone Lake is the largest high-altitude lake in North America. Beneath its surface lies an active geothermal system, including hot springs, geysers, and fumaroles. These underwater features create an alien-like landscape that is still being explored by scientists.
