Wolves vanished from Yellowstone for 70 years. In 1995, rangers brought back just 14 of them from Canada. What happened next surprised everyone. Elk changed how they moved. Trees grew back. Rivers changed course. One animal reshaped an entire ecosystem.
This guide covers Yellowstone's supervolcano, the real story behind Grand Prismatic Spring's colors, why the Tetons rise with no foothills, and the sacred rock formation that became America's first national monument.

Wyoming Quick Facts
Yellowstone established: 1872. The world's first national park, signed into law by President Ulysses S. Grant.
Old Faithful: erupts every 44 to 125 minutes, averaging about 90. Each eruption reaches 106 to 185 feet high.
Grand Prismatic Spring: Yellowstone's largest hot spring, roughly 200 to 330 feet across and about 121 feet deep. Water hits 189 degrees at the center.
Bison recovery: down to about 25 wild bison by 1902. Today's herd tops 4,000, the largest free-roaming herd on Earth.
Wolves reintroduced: 1995. 14 wolves brought from Canada after a 70-year absence.
Grand Teton: rises to 13,775 feet with no foothills leading up to it.
Devils Tower: 867 feet from its base (1,267 feet from the river valley). First U.S. national monument, designated 1906 by Theodore Roosevelt.
Wind River Range: about 100 miles long, with 40-plus named glaciers. Fremont Peak reaches 13,745 feet.
Pronghorn antelope: run up to 55 mph, the second-fastest land animal on Earth.
Wyoming itself: fewer than 600,000 residents across about 98,000 square miles. More wild land per person than any other state.
History & Origins
Wyoming has fewer than 600,000 people. It spans about 98,000 square miles. That leaves more wild land per person than any other state. Yellowstone sits at the heart of it. In 1872, President Ulysses S. Grant signed it into law. It became the world's first national park. The idea was new. Protect land instead of using it up.
The push for Yellowstone started with an 1871 survey. Geologist Ferdinand Hayden led it. Photographer William Henry Jackson went along. His photos were some of the first most Americans ever saw of the park. They helped convince Congress to act. That decision still shapes how the world thinks about wild land today.

A Supervolcano Under Your Feet
Yellowstone sits on top of a supervolcano. Two miles down, the ground reaches 1,500 degrees. That heat powers the largest geothermal system on Earth. Old Faithful taps right into it. It erupts every 44 to 125 minutes, averaging about 90. Each blast reaches 106 to 185 feet high. It has erupted more than a million times since records began.
Grand Prismatic's Living Colors
Grand Prismatic Spring is Yellowstone's largest hot spring. It measures roughly 200 to 330 feet across and about 121 feet deep. The water hits 189 degrees at its center. The colors aren't paint or minerals. They come from heat-loving bacteria. Each color marks a different temperature zone. Blue sits in the hottest center. Orange and yellow ring the cooler edges.
The Wolves That Changed a River
Wolves vanished from Yellowstone for 70 years. In 1995, rangers brought back 14 from Canada. What happened next surprised everyone. Elk started avoiding open valleys. Willows and aspens grew back. Beavers returned. Riverbanks stopped eroding. One predator, reintroduced, reshaped an entire ecosystem. Not bad for 14 wolves.
"In every walk with nature, one receives far more than he seeks."

Beyond Yellowstone
Grand Teton's Sudden Peaks
The Teton Range breaks the rules. Most mountains build up slowly with foothills. Not these. The valley floor just stops. Then rock shoots straight up to 13,775 feet. An active fault line causes the sudden rise. Mormon Row sits right in front of it. Homesteaders built those barns in the 1890s. The barns and the peaks line up perfectly. That's why photographers keep coming back.
Devils Tower's Sacred Rock
Devils Tower rises 867 feet from its base. From the river valley below, it's 1,267 feet. Magma pushed up long ago and cooled underground. Wind and water wore away the softer rock around it. What's left is solid, striped stone. In 1906, Theodore Roosevelt made it the first U.S. national monument. Native tribes call it Bear Lodge. It's still used for spiritual ceremonies today.
More Wyoming Wildlife
By 1902, poaching had reduced Yellowstone's wild bison to about 25. Rangers brought in ranched bison to rebuild the herd. Today's herd is the largest free-roaming bison population on Earth, more than 4,000 strong. Pronghorn antelope share the same plains. They run up to 55 miles per hour. That makes them the second-fastest land animal alive, right behind the cheetah.
