Mt. McKinley/Denali

This Alaskan mountain has changed names several times. Historically called Denali (meaning ‘the big one’) by the Koyukon Athabaskan tribe, it was referred to as Bolshaya Gora (‘big mountain’) by the Russians. After the Alaska purchase, it was temporarily named Densmore's Mountain before gaining the name McKinley in support of the then-presidential candidate. It was renamed Denali in the 1970s at the state level and in 2015 at the federal level, before reverting to McKinley in 2024, although Denali is still the name of the National park that houses it . With this many changes, it’s no wonder some people still mix the names.

Liberty Enlightening the World/The Statue of Liberty

This statue is one of the indisputable icons of the USA and of New York City, but not everyone knows that ‘The Statue of Liberty’ is just a popular name. As a gift from France, it was named La Liberté éclairant le monde , or ‘Liberty Enlightening the World’ , but no matter what it’s called, it has become an iconic symbol of American values.

Alcatraz Island/The Rock

One of the most infamous American prisons, Alcatraz Island, is located less than two miles from the San Francisco coast. Spanish explorer Juan Manuel de Ayala named it Isla de los Alcatraces or Island of the Pelicans due to the prevalence of these birds. After becoming U.S. territory, Alcatraz Island became a military fort, and then a federal prison that housed some of America’s most notorious criminals. While many believe that it's popularly called The Rock because it was impossible to escape, the nickname is simply due to its rocky appearance and its isolated location.

Mt. Rainier/Tahoma

Located in the Mount Rainier National Park, Washington, Mt. Rainier is the tallest mountain (and volcano) in the Cascade Range. Native American tribes of the area have given numerous names to this peak, but the most prominent one is Tahoma or Tacoma , a name still used by some. Officially, however, it is called Mt. Rainier , a name given by the British explorer George Vancouver in the 1790s.

5

Lake Superior/Gitche Gumee

The largest of the Great Lakes, Lake Superior, is one of the biggest freshwater reserves in the world. Its current name originated when French explorers, after traversing Lake Huron, called this lake le lac supérieur (‘the lake above’). After the French and Indian War, the British simply translated the name. However, this lake also has a native name, usually transliterated as Gitche Gumee, a name used by the poet Longfellow in his work The Song of Hiawatha .

6

Mt. Rushmore/The Six Grandfathers

This mountain has been considered a sacred place by many tribes of the region —such as the Arapaho, Cheyenne, or Lakota Sioux— who named it ‘The Six Grandfathers’ after their ancestral deities . The place gained its current name when Charles E. Rushmore, a lawyer surveilling the area as a representative of a mining company, asked the name of the mountain. His guide replied that it had no name, but it would from that day be called ‘Rushmore’. The name stuck, and was officially recognized a few decades later.

Mission San Antonio de Valero/The Alamo

The battle of the Alamo is a well-known episode in Texan history, and its location is considered a shrine to Texan valor and liberty. However, what many don’t know is that the place is called Mission San Antonio de Valero , a name given by the Spanish. Where does the ‘Alamo’ name come from? After the place stopped being used as a Catholic mission, it became a military fortress, housing a military unit nicknamed Álamo de Parras after their city of origin, a nickname that extended to the site.

8

Cloud Gate/The Bean

Chicago regulars (and even those who never set foot in Chicago) know that The Bean is as iconic as it gets when talking about the city. Inspired by liquid mercury, this impressive sculpture might be shaped like a ginormous jellybean, but its official name is Cloud Gate . The sculptor, Anish Kapoor, initially disliked the popular nickname, but he has reportedly come to terms with it, even saying that he now calls it ‘the Bean’ too.

9

State House Bell/Liberty Bell

At its birth, this bell was simply the bell of the Pennsylvania State House (now Independence Hall). Cast in the 18th century, it cracked the first time it was rung. It was recast twice, but it cracked again in the 19th century. Allegedly rung after the Declaration of Independence, it was hidden during the Revolutionary War, and it changed hands several times in the following century. Despite its popular association with the American Revolution, the ‘Liberty Bell’ name was actually given by anti-slavery groups , who took it as a symbol due to its inscription reading "Proclaim Liberty throughout all the land unto all the inhabitants thereof."

10

Cape Canaveral/Cape Kennedy

Originally named Cabo Cañaveral by the Spanish after its abundance of canes, its name was simply anglicized after the territory became part of the United States. In the 20th century, Cape Canaveral became the center of a series of missile and rocket tests, and it was the launch site of the Apollo 11 mission. A few days after J.F.K.’s assassination, the newly-instated President Johnson publicly announced that the cape would be renamed ‘Cape Kennedy’ as a memorial . The name change was not well-received by local Floridians, and the original name was reinstated a decade later, with the full support of the Kennedy family. The NASA space center is still named after President Kennedy.

The man who sold everything he owned and bet it all on one spin

In 2004, a 32-year-old British man named Ashley Revell walked into the Plaza Hotel and Casino in Las Vegas and placed every dollar he had in the world on a single spin of the roulette wheel.

In the months before, Revell had sold his house in Kent, his BMW, his Rolex watch, his golf clubs, his electronics, his furniture, and every piece of clothing he owned. The grand total of his liquidated possessions came to $135,300 . He pushed the entire stack of chips onto red as the ball was already spinning. It landed on Red 7.

Revell walked away with $270,600, exactly double what he had come in with. He tipped the croupier $600 on the way out. The whole thing was filmed by Sky One for a reality mini-series called Double or Nothing .

Beneath the casinos, an estimated 1,500 people live underground

Below the glittering hotels and neon lights of the Las Vegas Strip runs a network of concrete flood drainage tunnels stretching roughly 600 miles beneath the city. Built in the 1990s to manage flash flooding in the Nevada desert, these tunnels have become an unofficial home for hundreds of the city’s unhoused residents.

It is estimated that between 1,200 and 1,500 people live there . Some residents have constructed makeshift shelters from plywood and salvaged metal deep inside the tunnels, occasionally just yards below the casino floors above them.

The tunnels pose serious dangers: flooding risk during desert rainstorms, extreme heat, and high rates of substance abuse. A network of nonprofits, outreach teams, and government agencies coordinates aid by providing the residents with essentials and offering them long-term case management, like treatment and housing placement.

Las Vegas has a literal black book of people banned for life

Since 1960, the Nevada Gaming Control Board has maintained what it officially calls the List of Excluded Persons, better known as the Black Book. The original publication was a black-covered booklet held together with Scotch tape, listing eleven people deemed to have "notorious or unsavory reputations."

Most of the early entries were organized crime figures: Chicago outfit boss Sam Giancana; enforcer Anthony "Tony the Ant" Spilotro, whose violent exploits inspired Joe Pesci’s character in the film Casino ; and nine other mob associates. Anyone whose name appears on the list is permanently banned from entering any licensed gaming establishment in the state of Nevada.

Violating the ban is a gross misdemeanor under Nevada law. As of 2026, there are 37 names on the list. No one has ever successfully appealed their removal.

Strange casino rules: no clocks, no windows, no soft dice

Las Vegas casinos are designed to keep gamblers at the tables as long as possible. Clocks are banned to distract players from the passing of time. Windows are eliminated so that they cannot tell whether it is noon or 3 a.m.

What’s more, Nevada law governs even the dice. The Nevada Gaming Control Board requires casino dice to be perfectly transparent so that no hidden weights can be concealed inside . Each die must be precision-manufactured to within 1/10,000th of an inch, with razor-sharp corners and edges showing no rounding whatsoever. They are inspected regularly and, in high-stakes games, replaced every eight hours of play to ensure consistent rolls.

The famous Las Vegas Strip is not actually in Las Vegas

The stretch of Las Vegas Boulevard South that the world knows as the Strip does not lie within the city limits of Las Vegas. This is the area that’s home to Caesars Palace, the Bellagio, MGM Grand, the Venetian, Mandalay Bay, and dozens of other iconic venues.

Technically, it falls within an unincorporated community called Paradise , which is governed by Clark County rather than the city of Las Vegas. Paradise was deliberately established in 1950, when casino owners moved to avoid Las Vegas city taxes and regulations while continuing to trade on the city’s name and benefit from its infrastructure.

The city of Las Vegas actually begins further north along the boulevard, near the Stratosphere. Paradise covers approximately 54 square miles and has a residential population of around 220,000 people, which means it’s one of the largest and most densely populated unincorporated communities in the United States.

The Luxor’s sky beam is the most powerful artificial light on earth

Rising straight up from the apex of the black pyramid-shaped Luxor Hotel and Casino, the Luxor Sky Beam has been one of the most recognizable sights in Las Vegas since the hotel opened in October 1993. It is, by any measure, the most powerful artificial light beam on the planet. The beam is produced by 39 individual xenon lamps, each with 7,000 watts and roughly the size of a washing machine, focused through computer-designed curved mirrors into a single concentrated column.

Together, they generate an estimated 42.3 billion candlepower. On a clear night, airline pilots have reported seeing the beam from as far as 250 miles away. The total operating cost, confirmed by Luxor engineer John Lichtsteiner, is $51 per hour, of which $20 is electricity. That adds up to $480 a day only for lighting the signature beam each night —or $175,200 a year.

Las Vegas is home to the tallest observation tower in the US

Standing 1,149 feet above the Las Vegas valley, the Strat Tower, officially rebranded from the Stratosphere in 2020, is the tallest freestanding observation tower in the US and the second-tallest in the entire Western Hemisphere, surpassed only by the CN Tower in Toronto at 1,815 feet. It is also the tallest building in Nevada and the tallest structure west of the Mississippi River.

At the top, the Strat offers four outdoor thrill rides, including one that dangles riders 64 feet beyond the edge of the building on a mechanical arm, over 900 feet above the ground.

Slot machines account for around 60% of all casino revenue

Walk into any Las Vegas casino, and the first thing that surrounds you (and the loudest) is the rows of slot machines that line nearly every available wall and corridor. That layout is not a coincidence.

It is estimated that slot machines consistently generate approximately 60 to 65 percent of all casino gaming revenue in Nevada. There is roughly one operating slot machine for every eight residents of Las Vegas. Nevada law requires that video slot machines pay out a minimum average of 75 percent, though Strip machines in practice typically return 87 to 97 percent.

Casinos place the most visible, most tempting machines near entrances, elevators, and high-foot-traffic corridors , a placement strategy that has been studied and refined over decades. Despite the rise of poker rooms and sports betting in recent years, slot machines have remained the single largest source of gaming income in Las Vegas without interruption for more than half a century.

The gambling capital of the world does not sell lottery tickets

Nevada is one of only two states in the entire United States that have no state lottery, the other being Utah. You cannot legally walk into a convenience store and buy a $2 scratch-off ticket.

The reason is straightforward and has nothing to do with moral opposition. Nevada’s gaming industry has lobbied persistently and successfully against a state lottery since gambling was first legalized in 1931, on the grounds that a government-run lottery would directly compete with casino revenues.

FedEx was saved from bankruptcy by a Las Vegas blackjack table

In 1971, FedEx, then called Federal Express, was days away from collapse. Founder Frederick W. Smith had built the company on the revolutionary idea of overnight package delivery using a central hub-and-spoke air network, but the business was not working.

The company had roughly $5,000 left in its operating account. It was not enough. Facing what appeared to be the end, Smith flew to Las Vegas and sat down at a blackjack table. He gambled the company’s last $5,000 and turned it into $27,000, which was just enough to cover that week’s fuel costs and keep the planes in the air. The breathing room bought by that blackjack session gave Smith enough time to secure additional financing. Today, FedEx employs more than 500,000 people worldwide and is valued at over $60 billion.

Area 51

Location: Nevada

Shrouded in secrecy, this military base has become synonymous with UFOs and government cover-ups. Its official purpose was testing aircraft like the U-2 spy plane and Stealth Bomber, but its classified nature fueled decades of wild speculation, ranging from secret weapons to actual aliens working for the government.

Coral Castle

Image: Audric Wonkam

Location: Florida

This massive stone structure was built by a single man, Edward Leedskalnin, using enormous limestone blocks—some weighing 30 tons. According to him, no heavy machinery was ever used during the construction, and he even claimed to know the secrets of the pyramids . To this day, engineers and historians debate how he moved and placed those stones with such precision.

Skinwalker Ranch

Image: Jacob Padilla

Location: Utah

This 512-acre property has long been at the center of UFO sightings, cattle mutilations , and alleged portals to other dimensions. The stories were so compelling that, in the ’90s, a private research organization purchased the ranch to try and make some scientific sense of the claims, conducting extensive field studies. However, after nearly a decade of research, they found no conclusive evidence.

Mammoth Cave

Location: Kentucky

The world’s longest known cave system has its fair share of unexplored tunnels, ghost stories, and strange air currents. More than 400 miles have been mapped , yet many passages remain uncharted. Researchers have yet to fully understand the cave’s underground ecosystem, and new chambers are still being discovered today.

The Marfa Lights

Image: Alexandra Vo

Location: Texas

Reported since at least the late 19th century, floating orbs of light have been seen near this small town with no consistent explanation. Night watchers continue to gather at designated viewing areas along Highway 90, hoping for a glimpse. While scientific studies suggest that distorted car headlights are the most likely cause, many remain convinced otherwise.

The Devil’s Kettle

Image: Andrew Ling

Location: Minnesota

This unusual waterfall splits in two—one half flows normally, while the other vanishes into a deep pothole with no known exit. Scientists poured dye, ping-pong balls, and even GPS trackers into the mysterious hole, all to see where the water ends up. While researchers eventually confirmed it rejoins the river underground, exactly how and where remained elusive for decades.

Cahokia Mounds

Image: pcrm Dorego

Location: Illinois

Built centuries before Columbus arrived in the Americas, the ancient city of Cahokia featured massive earthen mounds, wooden palisades, and likely formed part of complex trade networks across the continent. Despite having a population rivaling London in the 1200s, according to archaeologists, the city was mysteriously abandoned in the span of a few years. No written records explain its decline, though environmental stress, resource shortages, and internal social factors are often cited as possible causes.

Blythe Intaglios

Location: California

Similar to Peru’s Nazca Lines, these giant geoglyphs are etched into the desert floor, seemingly visible only from the sky. Created by scraping away dark rocks to reveal lighter earth beneath, the figures are believed to be between 450 and 2,000 years old, depending on the specific design. While their exact purpose remains a mystery, they are believed to have had a ceremonial function.

The Spooklight

Image: Ben Griffiths

Location: Missouri-Oklahoma Border

Also known as the Hornet Spooklight, this floating orb has been seen since at least the late 19th century. It appears along a rural stretch of road near the small community of Hornet, Missouri, and Quapaw, Oklahoma. While some theorize it could be caused by car lights from miles away, some sightings predate automobiles.

Roanoke Island

Image: Stephen Crane

Location: North Carolina

In the 1580s, an entire colony vanished overnight, leaving behind only the word "Croatoan" carved into a tree. No graves, no remains—just an eerie disappearance that sparked centuries of theories, from disease and starvation to assimilation with local tribes. Modern archaeology uncovered European artifacts at sites associated with Native groups miles away, but no definitive evidence has ever solved the mystery.
