New York, The Empire State

Probably the most famous and recognizable state nickname, no one really knows who was the first to call New York State the "Empire State", but everyone agrees on the reason for the nickname. The state of New York has always been one of the richest, most developed, and strategically important territories in America , a powerhouse akin to an empire. George Washington himself had described it as "the seat of the Empire" in 1785, and many believe that these words were the source of the nickname.

2

Indiana, The Hoosier State

Another instantly recognisable nickname, the origin of the term ‘Hoosier’ is also widely debated. Believed to have emerged in the 1830s, some say that it is a deformation of the phrase "Who's here?". No matter its actual origin, the term was popularized by John Finley's 1833 poem "The Hoosier's Nest" , a description of rugged but welcoming Indiana pioneers, and it became a source of pride for the state, so much so that ‘Hoosier’ was officially adopted as a demonym by the state of Indiana in 2017.

3

Delaware, The First State

Delaware was not the first colony to exist or to become a state. In fact, Delaware wasn’t even a colony: it was technically part of Pennsylvania. The ‘first’ referenced in the nickname alludes to Delaware’s role in the ratification of the U.S. Constitution , a task that took time and political compromise, as several states had concerns about the document and its articles. But while it took nearly two years for all the states to ratify the Constitution, it took less than three months for Delaware to do so unanimously, setting a precedent for other states.

4

Virginia, The Old Dominion

Probably the oldest state nickname still in use, Virginia’s ‘Old Dominion’ nickname has existed for more than 400 years. The first English colony in America, Virginia was also the main colony to remain faithful to the monarchy during the English Civil War , supporting the exiled King, inviting him to take refuge in their territory, and resisting the siege from the Parliamentary fleet for a long time. After the restoration, King Charles II conferred the colony the title of ‘dominion’ —similar to a kingdom in rank— and affectionately called it "the most Ancient Colloney and Dominion."

5

Oklahoma, The Sooner State

Although it is now used as a symbol of a competitive and pioneering attitude, the term ‘Sooner’ was not always seen as positive. During the Land Rush of April 22, 1889, the U.S. government opened a territory —freed by the forced displacement of thousands on ative Americans— for pioneers to take. At noon, a bugle would signal that settlers could enter and claim areas of land. However, several pioneers broke the rules, entering the territory ‘sooner’ , before the signal. Initially a pejorative nickname, the people of Oklahoma eventually owned the term as a symbol of their ‘can-do’ attitude.

6

Connecticut, The Constitution State

Unlike what many people think, Connecticut’s nickname is not related to the U.S. Constitution. In fact, the ‘constitution’ referenced in it predates the American Constitution by more than a century. Unlike other colonies, established by royal charters, the Connecticut Colony was established through The Fundamental Orders , a document delineating a representative government based on "the free consent of the people". The Fundamental Orders are considered to be the first written constitution in Western modern history, a fact that gave Connecticut its nickname.

7

Tennessee, The Volunteer State

Out of the many things that showcase Tennessee’s patriotism, none is as old or as well-documented as its volunteer vocation. Starting during the Revolutionary War, with the Appalachian Overmountain men volunteering to fight during the Battle of King's Mountain, Tennessee’s men's willingness to volunteer as soldiers became known during the War of 1812 , with hundreds fighting under Andrew Jackson’s command and earning Tennessee the name of the Volunteer State. To further solidify it, when President James K. Polk asked Tennessee for 2,800 volunteers during the Mexican-American War of 1846, the state responded to the call by sending 30,000 volunteer troops.

8

Vermont, The Brave Little State

A relatively more recent nickname than others in this list, the description of Vermont as a ‘brave little state’ dates back to 1928. After a flood in 1927 resulted in nearly 100 casualties and millions of dollars in damages, President Coolidge, a Vermont native, visited the state to assess the situation. Coolidge, often seen as calm and taciturn, gave an emotional speech praising the efforts and the resilience of his fellow Vermonters , and their ties to a land that gave them sustenance but posed the hazard of natural disasters. Coolidge ended his speech by acknowledging the generosity of the people of "this brave little state of Vermont", a phrase that became so popular that it was later inscribed in the Vermont State House and became a common nickname for the state.

9

Wisconsin, The Badger State

Though badgers can be found across Wisconsin, they are far less common than one would think, especially considering the state’s nickname. But this nickname has little to do with real badgers and much to do with people behaving like a badger. In the 1820s, prospectors all over America travelled to Wisconsin to look for lead ore. Working all day in the mines and lacking proper housing, the miners usually ended up living in the mines or digging holes in the hillsides to serve as shelter , which led people to compare them with burrowing badgers. Eventually, the ‘badger’ nickname became a symbol of the tenacity of the miners, and a point of pride for all Wisconsinites, who campaigned in 1957 to officially adopt the badger as their state animal.

10

Nebraska, The Cornhusker State

Though this famous nickname for Nebraska has ties with the agricultural identity of the state, it actually originated in the world of college football. Before 1900, the University of Nebraska football team had used several nicknames, such as Bugeaters, Tree Planters, or Rattlesnake Boys. Following a rough patch and wanting to give the team a new direction, sportswriter Charles Sherman suggested the nickname ‘cornhusker’ as a homage to the traditional corn husking done by hand by the Nebraska settlers . The name caught on and was eventually made extensive to all Nebraskans, being officially adopted by the state in 1945.

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.

2

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.
