The Restless Giant
At the heart of Yellowstone's past, present, and future lies a SUPERVOLCANO. Huge volcanic eruptions occurred here, the latest about 631,000 years ago. The center of what is now the park collapsed, forming a 30- by 45-mile caldera, or basin. The heat powering those eruptions still fuels the park's geysers, hot springs, fumaroles, and mudpots.
The park's ECOSYSTEMS range from near-desert vegetation at the North Entrance to subalpine meadow and forest on Mount Washburn. They support a variety of habitats that sustain diverse wildlife like bison (buffalo), elk, grizzly and black bears, wolves, trumpeter swans, and Yellowstone cutthroat trout.
PEOPLE also have been part of Yellowstone for more than 13,000 years. Many Native American tribes still have deep connections here. Discover your own connections to the park as you explore its wonders.
The supervolcano feeds the world's largest group of HYDROTHERMAL FEATURES.
HOT SPRINGS are the most common hydrothermal features in the park. They vary from frothing mocha-like boiling water to clear and calm pools of tremendous depth. Surface water seeps underground, is heated by a deep source of magma, and rises to the surface as superheated water. Hot springs have no constrictions, so water rises, cools, and sinks freely.
GEYSERS erupt with steaming hot water. They are hot springs with narrow spaces in their plumbing, usually near the surface. The constrictions prevent water from circulating easily to the surface where heat would escape. The deepest circulating water can exceed the surface boiling point (199°F/93°C). The Old Faithful area has the most famous geysers; some eruptions can be predicted.
TRAVERTINE TERRACES are found at Mammoth Hot Springs, where the interactions of water and limestone create chalk-white travertine. These terraces are among the fastest changing features in the park, emerging quickly and drying up just as fast.
FUMAROLES (steam vents) are the hottest hydrothermal features in the park. The small amount of water in fumaroles flashes into steam before it reaches the surface. Fumaroles hiss, whistle, or thump if the steam pathway is restricted at the surface. They are easiest to see in cool weather. Look for fumaroles in the major hydrothermal areas.
MUDPOTS are acidic hot springs with a limited water supply. Acid from volcanic gases and microorganisms decompose the surrounding rock into clay and mud. Mudpot consistency and activity varies with the seasons and precipitation. You can see mudpots at Artists Paintpots, Norris Geyser Basin, Fountain Paint Pots, West Thumb Geyser Basin, and Mud Volcano.
EVERY CORNER of Yellowstone reveals the park's rich array of nature and history.

MAMMOTH HOT SPRINGS features ever-changing travertine terraces and historic FORT YELLOWSTONE. A self-guiding tour explores the US Army's role in protecting the park in its first decades.
NORRIS GEYSER BASIN is the park's hottest, most dynamic geyser basin. It includes Steamboat, the world's tallest geyser. The nearby Museum of the National Park Ranger showcases the history of these iconic public servants.
MIDWAY GEYSER BASIN hosts the world's largest geyser, Excelsior, and the world's largest hot spring, Grand Prismatic. Boardwalks take you past these features, and a nearby trail leads you to an elevated view.
OLD FAITHFUL is more than its namesake world-famous geyser. You can view hundreds of other geysers and hot springs. Take a self-guiding tour of the historic district, which includes Old Faithful Inn.
WEST THUMB includes mudpots, boiling springs, and geysers that discharge into the chilly waters of Yellowstone Lake. At the GRANT VILLAGE Visitor Center, enjoy the scenery while you learn about the role of fire in Yellowstone.
LAKE VILLAGE offers vistas of Yellowstone Lake from the comfort of historic Lake Hotel. The lake is the largest high-elevation lake (above 7,000 feet) in North America. It is more than 400 feet deep with 141 miles of shoreline.
CANYON AREA features the colorful Grand Canyon of the Yellowstone River and the Upper and Lower falls from overlooks and walkways. Away from the rim, trails take you through meadows and grasslands.
The LAMAR VALLEY has been a wolf watching destination since wolves were reintroduced to Yellowstone in 1995. It is also home to herds of bison and elk, and many black and grizzly bears.
THE WONDER OF YELLOWSTONE'S WILDLIFE
You have the rare opportunity to view animals who are wild. They behave like their ancient ancestors. They eat the same foods, they migrate along the same routes, and they breed on the same cycles. When you watch animals in Yellowstone, you glimpse the world as it was before humans.
Animals are seldom seen in the dense, dark forest that covers most of the park. They are more easily seen in open areas, like meadows, where vegetation is shorter and more light is available.
Other tips
• Look at dawn and dusk when many animals are most active.
• Be quiet and listen for a few minutes; you might hear animals
before you see them.
• Use binoculars or spotting scopes to observe animals while
staying at a safe distance.
STAY SAFE WHILE WATCHING WILDLIFE
The animals living in Yellowstone are not tame. All of them are wild. Some seem to tolerate humans, but that can change without warning. We jeopardize their survival if we threaten their safety, the safety of their young, or interrupt their ability to get food. Yellowstone has rules to keep both wildlife and humans safe.
Never feed animals, not even small ones like chipmunks.
Store all food properly. Keep food, cooking tools, coolers, and trash in a bear-resistant container unless in immediate use. Animals who find food at picnic areas and campsites will come back, and can be dangerous.
Do not approach wildlife. You must stay at least 100 yards from bears and wolves, and 25 yards from bison, elk, and other animals.
Pay attention. Move away if an animal moves closer to you or changes its behavior due to your presence.
Be respectful. Do not surround, crowd, or disrupt an animal's path of movement.
STAY SAFE IN THERMAL AREAS
Yellowstone National Park also has rules to keep you safe as you visit its hydrothermal areas.
• Stay on boardwalks and designated trails.
• Do not push or shove other people.
• Keep your children close to you.
• Keep hands and feet out of the water.
