South Dakota sits right in the middle of it all

Image: Intricate Explorer

Just outside the town of Belle Fourche, South Dakota, lies the geographic center of the United States when you include Alaska and Hawaii . It is not marked with neon signs or big crowds, but there is something satisfying about standing near the heart of the whole country. It feels like the center of gravity for the U.S.

Iowa is flanked by rivers on both sides

Image: Justin Wilkens

If you look at a map, you will see Iowa neatly tucked between two mighty rivers . The Mississippi River borders it to the east, and the Missouri River forms most of its western boundary. No other state can say that its entire east and west borders are made up of rivers. That gives Iowa a front-row seat to river life from both sides.

Kansas is flatter than a breakfast pancake

Believe it or not, a group of researchers once compared Kansas to a pancake and found that Kansas is actually flatter . This was not a joke. They used real measurements. If long, open roads and wide horizons are your thing, Kansas is the ultimate smooth ride.

Arizona has all the deserts in one place

Image: Keith Hardy

Arizona is not just dry, it’s uniquely arid. It is the only state that includes parts of nearly all of the major North American deserts . These include the Sonoran, Mojave, Chihuahuan, and Great Basin deserts. That makes it a desert lover's dream and a living science exhibit where four very different ecosystems meet in one sunbaked state.

Michigan lives and breathes freshwater

Image: Aaron Burden

Michigan has more freshwater shoreline than any other state in the country. It borders four of the five Great Lakes , features two peninsulas, and is even home to a floating post office that delivers mail by boat. If you enjoy water views and lakeside life, Michigan delivers the goods in a big way.

Connecticut gave counties the pink slip

Image: Rusty Watson

Unlike most states, Connecticut does not have county governments. The state decided back in the late 1950s and early 1960s to get rid of them entirely. Now, counties are just lines on a map and have no political power. If you live in Connecticut, you deal directly with your town or city. No middleman needed.

Delaware still uses ‘hundreds’ and no, not the money kind

Image: Gary Cole

In Delaware, land is still divided into areas called hundreds . These are old British-style subdivisions that originally represented areas able to support roughly 100 households. While they do not play a role in law or government today, the names still show up in property documents and tax records.

Kentucky hides the longest cave under its feet

Image: Joshua Sortino

Beneath Kentucky’s surface lies a giant underground wonder called Mammoth Cave. It holds the record as the longest known cave system in the world , with over 400 miles of mapped tunnels. That is a whole lot of rock and mystery. Whether you are into history, geology, or just cool natural landmarks, this cave system is something special.

Louisiana prefers parishes over counties

Image: Joe Lavigne

Louisiana does not have counties like the rest of the country. Instead, it has parishes , a term carried over from its French and Spanish colonial days. These parishes work the same way counties do elsewhere, but the name gives the state a unique cultural twist.

Montana provides the nation's platinum and palladium

Image: Calvin Chai

Montana is the only significant source of domestically mined platinum and palladium in the United States. These rare metals are used in things like jewelry, dental tools, and car parts. Tucked into its rugged mountains, Montana’s mines quietly produce some of the most valuable materials in the country.

Wisconsin has an official microbe, and it makes cheese

Image: Azzedine Rouichi

Of course, Wisconsin would go this route. The state named Lactococcus lactis as its official microbe. It is the helpful little organism behind the cheese-making magic. Without it, you would not have cheddar, Colby, or many other favorites. Leave it to the dairy state to give a tiny cheese-maker its moment of fame.

The Cardiff Giant

In 1869, workers digging a well in Cardiff, New York, uncovered what appeared to be a 10-foot-tall petrified man. Locals rushed to see the "giant," paying admission to witness history in the soil.

But, as it turned out, it wasn’t ancient at all. A man named George Hull had buried the statue as a prank and made some quick money from the curious crowd.

2

War of the Worlds Broadcast

This very famous hoax took place on the eve of Halloween 1938. Orson Welles’s radio adaptation of The War of the Worlds aired as if it were breaking news . Many listeners tuning in late thought Martians had really landed in New Jersey.

Some packed up their cars or called the police in panic. Though no invasion occurred, the broadcast became a legend in media history.

3

The Balloon Boy

In 2009, Americans watched live TV coverage of a silver balloon drifting across the skies of Colorado , fearing that a six-year-old boy was trapped inside . The story gripped the nation for hours.

When the balloon finally landed empty, police discovered the child hiding safely at home. His parents later admitted it was a publicity stunt gone wrong.

4

The Feejee Mermaid

In 1842, showman P. T. Barnum unveiled a marvel: a preserved "mermaid" supposedly from the South Seas . Crowds lined up to see the half-fish, half-woman curiosity.

The truth was stranger still. It was the upper body of a monkey sewn onto a fish tail and covered in papier-mâché.

5

The Great Moon Hoax

Readers of The New York Sun in 1835 were astonished by reports claiming that scientists had spotted bat-like people and crystal palaces on the Moon through a powerful new telescope.

The story was pure invention, but circulation went up. By the time the truth came out, the paper’s readership had reportedly increased dramatically.

6

The Crop Circles Craze

When perfect circles began appearing overnight in wheat fields , people talked about UFO landings. The shapes seemed too precise to have been made by human hands.

But, in 1991, two Englishmen confessed they’d used boards and ropes to flatten the crops. While this revelation explained many of the formations, the mystery lives on in popular imagination.

7

Alien Autopsy Film

In 1995, a grainy black-and-white video surfaced, showing doctors dissecting what seemed to be an alien recovered from the 1947 Roswell crash. The footage spread quickly worldwide.

Years later, the filmmaker admitted that the film was staged, using latex models and fake organs.

The Manti Te’o girlfriend hoax

Notre Dame football star Manti Te’o captured hearts when he revealed that his girlfriend had died of leukemia . Sports fans wept over the tragic love story.

But reporters later learned that the woman never existed. It was an elaborate online catfishing scheme.

The Patterson–Gimlin Bigfoot film

In 1967, a short film shot in California showed a large, hairy creature striding through the woods . Many viewers thought this was real proof of Bigfoot´s existence.

Decades later, one participant claimed it was a man in a gorilla suit, but that claim failed to convince many people who prefer to believe in the existence of this creature.

10

The Drake’s Plate of Brass

In 1936, a shiny brass plate found in California seemed to confirm that explorer Sir Francis Drake had landed there in 1579. Historians called it a priceless relic.

For decades, the plate was displayed proudly, until metallurgical tests in 1977 proved it was modern . It had been made as a practical joke among historians that went too far.

11

Paul Is Dead

The final entry on our list might not be American per se, but it drew much attention on these shores. In 1969, rumors spread that Beatle Paul McCartney had died and been secretly replaced by a double . Fans scoured album covers for "clues" like hidden messages and backward songs.

Paul, very much alive, later joked about it. The bizarre theory became a lasting pop-culture phenomenon.

Dundas Castle, Roscoe, New York

Image: Annie Spratt

Also known as Craig-e-Clair, this castle was built by Ralph Dundas in the early 20th century. It is an architectural marvel of stone and copper.

Dundas died before the castle was completed, and his wife was reportedly committed to a sanitarium shortly after. Consequently, no member of the Dundas family ever actually lived in the mansion. This has led to the "Ghost of Dundas Castle" legends, with locals claiming to see a woman in white wandering the unfinished halls, waiting for a housewarming party that never happened.

Rockwell House, Milledgeville, Georgia

Image: Clem Geiss

Built in 1838, the Rockwell House is a stunning example of Federal-style architecture, but its beauty is shadowed by a dark past. It was originally built for Colonel Samuel Rockwell, a prominent lawyer.

Local lore whispers about the "Rockwell Ghost," believed to be a young girl who died during a yellow fever outbreak. However, the house’s most tangible secret lies in its survival; it has endured multiple fires and periods of extreme neglect. In recent years, it has become a focal point for preservationists who uncovered hidden structural reinforcements that suggest the house was built to be an impenetrable fortress of its era.

3

Elda Castle, Ossining, New York

Image: Nitrogel

If the name David Abercrombie sounds familiar, it’s because he co-founded the clothing company Abercrombie & Fitch . But in the 1920s, he also built this granite castle, named Elda (an acronym of his children’s names), as a secluded retreat.

The castle features a network of spiral staircases and open-air porches designed to blend the indoors with the rugged wild. Its abandonment, however, is a sheer tragedy. After the family moved out, the castle was used as a research facility and later fell victim to vandals. Legend has it that a fire in the 1940s was started by squatters, leaving behind a charred stone husk that resembles a medieval ruin more than a 20th-century home.

Mongo's Castle, Memphis, Tennessee

Image: Denny Müller

A stark contrast to the classical mansions of the South, Mongo’s Castle was the passion project of Mongo Bebe, a man who built his home out of scrap stone, Ashlar blocks, and found materials.

The house is a maze of folk-art eccentricity. The builder intended it to be a community center and a symbol of African-American heritage and self-reliance. It stands today as a decaying puzzle, with many neighbors still unsure of the structural logic behind its towering, uneven walls.

Bannerman's Castle, Pollepel Island, New York

Rising from the Hudson River, this castle was never intended to be a home; it was a giant advertisement and warehouse for Francis Bannerman VI’s military surplus empire.

In 1920, 200 tons of gunpowder and shells exploded in the castle’s powder house, blowing out a significant portion of the walls. The ground is still considered unstable due to the remnants of military munitions, and the inscriptions on the walls are actually warnings and advertisements for the Bannerman business. Do you dare visit this mansion?

6

Castle Mont Rouge, Rougemont, North Carolina

Image: Florian Delée

This whimsical, onion-domed castle looks like it belongs in the Russian countryside rather than the North Carolina woods. It was designed by sculptor Robert Mihaly, but he ended up abandoning the project in the early 2000s following a personal tragedy and financial hurdles.

The castle remains an "empty sculpture," filled with intricate marble work and unfinished turrets. The bizarre architectural fusion lacks a standard floor plan, making it nearly impossible to convert into a functional residence without destroying its artistic integrity.

7

Ha Ha Tonka Castle, Camdenton, Missouri

Image: Hannah McBride

Robert Snyder, a wealthy Kansas City businessman, began building this European-style castle in 1905. He wanted a retreat that overlooked the breathtaking Ha Ha Tonka Spring.

Yet, Snyder never got to see his dream finished; he was killed in one of Missouri’s first recorded automobile accidents just a year after construction began. His sons finished the castle, but it was gutted by a fire in 1942. There’s a hidden network of caves beneath the castle, which were rumored to be used by outlaws and later as a natural "refrigerator" for the estate’s kitchen.

Carleton Island Villa, Cape Vincent, New York

Image: Tama66

This once-magnificent villa was built for William Wyckoff, who made a fortune with the Remington Typewriter Company.

The Secret: Wyckoff’s dream turned into a nightmare on the very first night he stayed in the house. He suffered a massive heart attack and died in his sleep. His wife had passed away a month prior, leaving the villa to a son who had no interest in it. The house has stood empty for over 70 years, its secret being the tragic "cursed" timing that prevented it from ever functioning as a family home.

9

Dicksonia Plantation, Lowndesboro, Alabama

Image: Theo Bickel

Dicksonia was a quintessential antebellum mansion, featuring the massive columns and wrap-around porches synonymous with the Old South.

Unlike many plantations that were destroyed during the Civil War, Dicksonia survived the conflict only to be destroyed by a mysterious fire in 1939. Its "ghost pillars," however, remained standing long after the wooden house burned away. These towering brick columns became a haunting landmark , representing the structural skeletons of a forgotten social order.

10

Wyndcliffe, Rhinebeck, New York

Image: Peter Herrmann

This house is the literal origin of the phrase "Keeping up with the Joneses." Though often referred to as a "Mystery Mansion" by urban explorers, this is the ruin of Wyndcliffe, the estate of Elizabeth Schermerhorn Jones.

Elizabeth’s mansion was so grand and intimidating that it prompted her neighbors—including the Astors—to build even larger homes to compete. The secret of Wyndcliffe is the psychological impact of its architecture; it was built to inspire envy, and its current state of absolute decay is a poetic commentary on the fleeting nature of social status.
