George Washington had wooden teeth

When one thinks about this one, it can sound quite preposterous, but many people still believe it to be true. George Washington did wear dentures, but none were made of wood. His sets were crafted from ivory, gold, lead, and even animal and human teeth. The wood myth likely spread because stained ivory took on a rough, brown look .

The story stuck because it seemed to fit the image of a rustic leader. In truth, Washington’s constant dental pain was very real, but the wooden teeth are pure fiction.

The Declaration of Independence was signed on July 4

Yes, July 4, 1776, is remembered as the day America declared independence, but most delegates did not sign the document then. It was approved that day, yet the majority of signatures were added on August 2 .

Only John Hancock and perhaps a handful of others signed on the Fourth. The legend of all the Founders signing together created a more dramatic story than reality.

The first Thanksgiving had turkey and pie

The 1621 gathering in Plymouth is remembered as a feast of turkey, stuffing, and pumpkin pie. In reality, the menu was very different. Venison, fish, shellfish, corn, and nuts were likely served instead .

Turkey may have been present, but it wasn’t the centerpiece, and sweet pumpkin pie was impossible without sugar or ovens. The foods we associate today were added later by tradition.

The Liberty Bell cracked on July 4, 1776

Many believe the Liberty Bell cracked while celebrating independence on July 4, 1776, but it didn’t. The bell wasn’t even rung that day, and its famous fracture appeared decades later .

Records suggest the crack happened in the 1830s or 1840s during use at civic events. The legend tied the crack to 1776 because it made for a more patriotic tale.

5

Paul Revere shouted "The British are coming!"

Paul Revere’s midnight ride is legendary, but the famous phrase attributed to him is not. He likely warned townspeople, "The Regulars are out," since most colonists still thought of themselves as British.

The dramatic version was added later to make the story more exciting. Revere’s actual mission was successful, but it didn’t involve shouting through the countryside.

Colonial Americans were short

It’s often said that colonial Americans were much shorter than people today, but that’s an exaggeration. Skeletal evidence shows the average man in the 1700s was about 5’8", not far from modern averages .

Malnutrition was less severe in America than in Europe at the time. The myth spread from comparing old, small doorways and beds, which were not actually built for shorter people.

The pilgrims landed on Plymouth Rock

The story that the Pilgrims stepped onto Plymouth Rock in 1620 has no basis in fact. No historical accounts from the time mention it.

The tale was first told more than a century later, likely to create a symbolic landmark. The rock is real, but its role in the landing is pure invention to add drama to history .

Benjamin Franklin discovered electricity with a kite

Image: Brett Wharton

Benjamin Franklin’s 1752 kite experiment is well-known, but he didn’t "discover" electricity. Scientists had known about it for years. His test demonstrated that lightning was a form of electricity . So, somewhat similar but not the same.

The story became simplified over time into a myth of sudden discovery. Franklin’s real contribution was proving a connection, not inventing the concept.

9

The Alamo defenders fought to the last man

Image: Gabriel Tovar

The legend of the Alamo says every defender fought to the bitter end in 1836. While most did die, accounts suggest some may have surrendered and were executed afterward .

The truth is more complicated than the heroic version. Still, the myth of total sacrifice became central to Texas identity and American lore.

10

Lincoln wrote the Gettysburg Address on an envelope

Image: Forest Simon

Abraham Lincoln’s Gettysburg Address is often said to have been scribbled quickly on the back of an envelope. In reality, he drafted several careful versions of the speech in advance .

The "envelope" tale was later invented to emphasize his brilliance and spontaneity. The truth shows Lincoln was thoughtful and deliberate, not hurried.

11

Gunfights were really common in the Wild West

Image: Stefan Münz

Popular film and TV shows depict the Wild West as lawless and violent, with constant gun duels. In fact, frontier towns often had strict laws banning guns inside city limits .

Shootouts like those in movies were rare events, not daily life. The myth grew from dime novels and later Hollywood Westerns that exaggerated violence.

12

A cow started the Chicago Fire

Image: Daniel Quiceno M

The Great Chicago Fire of 1871 was long blamed on Catherine O’Leary’s cow kicking over a lantern. This story was published in newspapers and stuck in public memory.

Historians now know the cause was never proven . The cow tale unfairly tarnished the O’Leary family (and the cow itself), but it became a convenient explanation for a devastating disaster.

What are bills made of?

Unlike other currencies, dollar bills are not made of paper or plastic. U.S. dollar bills are made from a special fabric blend composed of 75% cotton and 25% linen. This mix makes the bills extremely durable and resistant, and they can be folded about 4000 times before tearing.

2

What bills are valid?

Any U.S. dollar bill that was legally printed is valid, no matter how old, as American currency does not have an expiration date. While some bills might not be accepted by businesses of foreign exchange services due to their condition or if they are a discontinued version of the bill, the bills themselves are still valid, and American banks will accept them, though they might take them out of circulation.

3

American leaders

Five bills have a depiction of an American president. The exceptions are the $10 bill, with Alexander Hamilton on the front, and the $100 bill, with Benjamin Franklin. The $1 bill, depicting George Washington, is extremely symbolic: several elements are repeated 13 times as a nod to the thirteen colonies, and it showcases the Bald Eagle and the Eye of Providence as a sign of God watching over America.

4

A change in size

Did you know that dollar bills used to be so big that they were nicknamed "horse blankets"? Original dollar bills were 7.4 × 3.1 inches. In 1929, the Treasury Department reduced the size of bills to 6.14 × 2.61 inches to reduce production costs and materials. Old bills, though still valid, are worth much more as collector items.

5

Uniformity

Besides their value and design, all dollar bills have the same size (6.14 × 2.61 inches), color, and weight (1 gram) , which sets American currency apart from other countries where bills of different values are differentiated by size, color, or both. Why doesn’t the U.S. implement differences among bills? The cost of adapting vending machines, bank drawers, and ATMs to new bill sizes would cost billions of dollars.

6

Hard to copy

Originally, dollars were not green, but black. As time passed, green ink was favored, as it was cheap and did not fade as much as black. The new color also prevented people from using black-and-white cameras to create counterfeit money. Currently, dollar bills are predominantly green, but newer versions also include extra colors, such as pink, orange, or purple.

7

A $100,000 bill?

Have you ever seen a $500 or 1,000 dollar bill? What about a $100,000? Up until 1945, the U.S. Treasury printed $500, $1,000, $5,000, $10,000, and $100,000 notes , in addition to the values currently in use. These higher-value notes were mainly intended for bank and government use, but were sought by criminals as they made it easier to hide large amounts of money. Even though they were officially discontinued in 1969, these notes are still valid, though rare, and they have a high worth as collector's items.

8

No numbers

Unlike bills, American coins have different sizes and colors related to their value. Originally, gold, silver, and copper were used for coins, but modern coins are made of copper, zinc, or nickel. Besides their size and design, the value of each coin is printed in letters, not in numbers , alongside depictions of American presidents.

9

Liberty for all (the coins)

By law, all American coins must include six specific details : the word ‘Liberty’, the name of our country, the national motto "In God We Trust", the oldest American motto "E Pluribus Unum", the value of the coin, and the year. Each coin also includes a mint mark that shows where it was made: "P" for Philadelphia, "D" for Denver, "S" for San Francisco, and "W" for West Point.

10

A global currency

The American dollar is one of the most powerful currencies in the world, acting as a backbone for international trade and finances. It is estimated that two-thirds of the physical dollars in circulation are outside American territory. Besides the U.S. and its territories, eight sovereign nations have the U.S. dollar as their official currency, with several more accepting it as legal tender.

There's an unexplained billion-year gap

Look closely at the canyon walls, and you'll notice something strange: a clean, sharp line where ancient rock simply stops, and a much younger layer begins directly above it.

This geological puzzle is called the "Great Unconformity," and it represents over a billion years of rock layers that are simply absent , as though that stretch of time never happened. In some spots, rock dated 1.8 billion years old sits directly beneath rock that is only 520 million years old. Where did the missing billion years go?

The leading theory involves the violent breakup of an ancient supercontinent, but scientists are still piecing it together.

During the Cold War, it hid a nuclear fallout shelter

During the Cuban Missile Crisis in 1962, the U.S. government converted part of the Grand Canyon Caverns into a fallout shelter. This dry cave system, more than 200 feet underground, was stocked with enough food and water to sustain 2,000 people. Naturally, it was never occupied, and the supplies were never used.

The caverns have since been transformed into a tourist attraction, with organized tours winding through the same underground chambers that were once intended as a refuge from nuclear war. You can even book a night's stay there.

The Federal Aviation Administration was founded after a crash over the canyon

In 1956, two commercial passenger planes collided in midair over the eastern Grand Canyon, killing all 128 people on board both crafts. Rescue teams struggled to reach the wreckage deep inside the canyon, and the extreme heat of the crash had caused the planes' aluminum to fuse with the bedrock. There were no survivors.

The disaster exposed a terrifying truth: the U.S. air traffic control system was dangerously outdated, relying on pilots' visual estimates and rough guesswork from controllers , with no way to separate fast-moving aircraft from slow ones, or instrument-flying planes from those navigating by sight. Congress responded by passing legislation that created both the Federal Aviation Administration (FAA) and the National Transportation Safety Board.

4

A hoax suggested that an Egyptian civilization had lived there

In 1909, the Arizona Gazette reported that an explorer named G. E. Kinkaid had discovered a vast underground citadel inside the canyon, filled with artifacts linked to ancient Egyptian civilization. He even claimed the expedition had been funded by the Smithsonian.

This story described hieroglyphics on the walls, mummies in the chambers, and relics pointing to a direct connection with the Egypt of the pharaohs. It was incredibly detailed, and it was, of course, a hoax. No evidence for any of Kinkaid's claims ever surfaced.

5

Fewer than 100 people have ever hiked its full length

Among the few people who have completed the through-hike of the Grand Canyon is Jen Hogan, the first woman to accomplish it, finishing her journey in 2021–2022.

It’s a full 800-mile length below the rim. The route involves extreme heat, flash floods, near-impassable areas, and stretches with no water or trail whatsoever. Around 60 or 70 people have reportedly accomplished it. This makes it one of the most exclusive feats on Earth.

6

The Grand Canyon's rocks predate dinosaurs entirely

Visitors scanning the canyon walls for fossils are often surprised to learn they won't find any dinosaur bones here. The rock layers of the Grand Canyon are simply older than dinosaurs. This fact alone can be shocking: staring at its walls means staring at marine fossils from as far back as 1.2 billion years ago. Some of its caves hold the remains of ancient mammals. The canyon is a window into a world that existed long before the dinosaurs, when the land that is now Arizona lay beneath a shallow sea.

7

The park is bigger than Rhode Island

Numbers alone rarely capture the Grand Canyon's scale, so here's a different approach. Rhode Island covers about 1,214 square miles, and the Grand Canyon National Park spans 1,904 square miles.

The canyon's depth exceeds four Empire State Buildings (which is 1,454 feet) stacked on top of one another. That’s 6,093 feet at its deepest point.

8

But it's not the deepest canyon on Earth

For all its grandeur, the Grand Canyon does not hold the depth record. Pictured above, the Yarlung Tsangpo Grand Canyon in Tibet, China, plunges to 17,567 feet, which is nearly three times deeper. Carved by the Yarlung Tsangpo River as it cuts through the eastern Himalayas, that canyon is so remote and extreme that it remained largely uncharted until the late 20th century.

9

It is home to a pink rattlesnake found nowhere else on Earth

The Grand Canyon Pink Rattlesnake has a pinkish-red coloring that matches the canyon's own distinctive rock walls so closely that it's nearly invisible. It is found nowhere else in the world. Officially classified as Crotalus oreganus abyssus , it has darker diamond-shaped markings along its back that deepen the camouflage further.

10

There's a village at the bottom: Supai Village

For over 1,000 years, the remote village of Supai has been home to the Havasupai Tribe, the People of the Blue-Green Waters. It is located an eight-mile hike from the rim, but sits roughly 3,000 feet deep inside the Grand Canyon.

The U.S. Department of Agriculture has called it the most remote community in the contiguous United States, and it has no automobiles and no road access. The only ways in are on foot, by mule, or by helicopter. It is also the only place in the United States where the postal service still delivers mail by mule train.
