Wyoming is a land of dramatic landscapes, rich history, and surprising facts. Although it’s one of the largest U.S. states by land area, it has the smallest population. Known as the “Equality State,” Wyoming has often led the nation in social change and environmental preservation. From stunning national parks to fossil-filled deserts, this state packs more fascination than its low population suggests.
Here are some of the most interesting facts about Wyoming that make it stand out.
1. The Equality State
Wyoming earned its nickname, The Equality State, for a good reason. In 1869, it became the first U.S. territory to grant women the right to vote. This bold move was part of a broader push to attract settlers and promote equality.
Wyoming later made history again in 1925 when it elected Nellie Tayloe Ross as governor. She wasn’t just Wyoming’s first female governor—she was the first woman to serve as governor in any U.S. state. Ross continued to break barriers by serving as Director of the U.S. Mint from 1933 to 1953.
2. Home of Yellowstone: The World’s First National Park
Wyoming is best known for Yellowstone National Park, which sprawls across the northwestern corner of the state and extends into Idaho and Montana. Established in 1872 under President Ulysses S. Grant, Yellowstone became the first national park in the world.
It covers over 3,400 square miles of wilderness, lakes, rivers, canyons, waterfalls, and geysers. Yellowstone is home to wildlife like bison, bears, wolves, and elk. It’s also a geothermal wonderland with over half of the world’s geysers, including the famous Old Faithful, which erupts regularly.
3. The Grand Prismatic Spring
Among Yellowstone’s many natural wonders is the Grand Prismatic Spring, located in the Midway Geyser Basin. It’s the largest hot spring in the United States and the third-largest in the world, measuring about 300 feet in diameter.
Its vivid bands of orange, red, yellow, and blue are created by pigmented bacteria that thrive in the varying temperatures of the mineral-rich water. However, this beauty is scalding hot—reaching up to 160°F (70°C)—and unsafe for swimming.
4. Devils Tower: America’s First National Monument
Rising dramatically from the plains of northeastern Wyoming, Devils Tower stands 867 feet from base to summit. This massive igneous formation was declared the first U.S. National Monument by President Theodore Roosevelt in 1906.
Known to Native American tribes by names like Matȟó Thípila (Bear Lodge) and Wox Niiinon, the tower is considered sacred. It’s also a popular climbing and hiking destination and gained pop culture fame from the film Close Encounters of the Third Kind.
5. A Unique River Renaming Ceremony
In central Wyoming, you’ll find a rare geographical curiosity—the “Wedding of the Waters.” As the Wind River flows out of Wind River Canyon, it suddenly becomes the Bighorn River. This name change occurs near the town of Thermopolis.
Although it’s the same river physically, the shift in name reflects a long-standing geographic tradition rather than a geological boundary.
6. The Red Desert and Great Divide Basin
Wyoming’s Red Desert is a vast, high-altitude desert that covers part of the southern portion of the state. It’s home to the Great Divide Basin, a unique endorheic basin where water doesn’t flow to any ocean. Instead, precipitation remains trapped within the basin, forming temporary lakes and wetlands.
This creates a strange hydrological divide. It’s one of the few places where the Continental Divide splits and rejoins, enclosing the basin in the middle.
7. Low Population, Wide Open Spaces
Despite being the 10th largest state by area, Wyoming is the least populated U.S. state. As of the latest census, it has around 580,000 residents—less than the city of Milwaukee.
This low population density offers benefits: less traffic, more access to public lands, and plenty of room to roam. By contrast, New Jersey—13 times smaller—has more than 8 million people.
8. More Pronghorns Than People
Wyoming is also home to a unique wildlife statistic: pronghorns outnumber humans. These speedy animals are often mistaken for antelope, though they’re a separate species.
Capable of speeds up to 55 mph, pronghorns are the second fastest land animals, just behind the cheetah. They’re found all across Wyoming’s plains and are a favorite among wildlife watchers and hunters alike.
9. The Cowboy State
Alongside “Equality State,” Wyoming is sometimes called the Cowboy State. The iconic bucking horse and rider emblem first appeared on military equipment during World War I and later became a state symbol in 1936, appearing on license plates and state branding.
This enduring image reflects Wyoming’s deep connection to cowboy culture, rodeos, and ranching.
10. A Coal Powerhouse
Wyoming is America’s leading coal producer. Since 1986, it has contributed more coal than any other state. In fact, at its peak in the 1990s, the state produced over three million tons of coal per week.
The Powder River Basin holds some of the largest coal reserves in the nation. Coal still plays a major role in Wyoming’s economy, though the state has started diversifying into wind and natural gas.
11. A Retail Giant’s Humble Beginning
J.C. Penney, one of America’s oldest department store chains, started in the small Wyoming town of Kemmerer in 1902. Founded by James Cash Penney, the first store was called “The Golden Rule.”
Today, the original store still operates as a museum and retail space, while the company has grown to hundreds of locations nationwide.
12. Carbon County and the Coal Connection
Wyoming’s relationship with coal goes back centuries. In 1867, the first commercial coal mines opened in southern Wyoming. One of the early coal-producing regions became known as Carbon County, a name that reflects its fossil fuel heritage.
These mines played a key role in powering the transcontinental railroad and the growing American West.
13. What’s in a Name?
The name “Wyoming” comes from a Lenape Native American word—mecheweamiing—which means “at the big plains.” While the term originally described a valley in Pennsylvania, it was chosen for the Wyoming Territory in 1865.
The name suits the state’s High Plains, especially in the eastern region, where wide, elevated prairies stretch for miles.
14. Big Parks, Big Tourism
Wyoming is a magnet for outdoor lovers. Besides Yellowstone, it’s also home to Grand Teton National Park, located just south of Yellowstone. The Tetons offer dramatic peaks, glacial lakes, and excellent hiking, climbing, and wildlife viewing.
Together, these parks draw millions of visitors each year, making tourism a crucial part of the state’s economy.
15. Cheyenne: Capital with a Rodeo Heart
Wyoming’s capital, Cheyenne, isn’t just the largest city in the state—it’s also known for Cheyenne Frontier Days, the world’s largest outdoor rodeo and western celebration. Held every July, the event features bull riding, parades, concerts, and more.
Cheyenne blends government, western culture, and urban amenities, all with a small-town feel.
