George Washington - The whiskey-making Founding Father

After leading the nation, George Washington stepped into the world of spirits, whiskey spirits, that is! In 1797, his farm manager convinced him to open a distillery at Mount Vernon . Within two years, it became one of the largest in the country, producing nearly 11,000 gallons of whiskey annually.

Here’s a fun fact: Washington didn’t need a marketing team. His whiskey was sold in unmarked barrels to local merchants, and his operation was so successful that it became one of the top money-makers in the area. The best part? You can try it today at the reconstructed distillery!

Not one to sit still, Theodore Roosevelt went on an exploration of the Amazon rainforest after leaving office. In 1913, he embarked on a seven-month journey to map an uncharted river . Guess what it’s called today? The Roosevelt River, of course!

The expedition was grueling: he caught malaria, suffered a leg injury, and nearly died. Though he made it back home, his health never fully recovered. Roosevelt’s post-presidency was all about adventure and risks!

Thomas Jefferson - The University Founder

Thomas Jefferson didn’t just help write the Declaration of Independence; he also founded the University of Virginia . A firm believer in education, he wanted to create a university that emphasized academic freedom and rigorous learning. So, in 1819, ten years after leaving office, he established the University of Virginia, which opened in 1825.

Jefferson personally designed the campus, including its iconic Rotunda, and hand-picked the first professors. He once called the university one of his greatest accomplishments, right up there with drafting the Declaration of Independence.

John Quincy Adams - From President to Congressman

John Quincy Adams didn’t believe in retirement, you know? He didn’t go back for a second term, but instead of stepping away from public service, he returned to Congress, serving in the House of Representatives for nine terms until his death in 1848.

His dedication earned him the nickname "Father of the House." Even in his final moments, he was working: he collapsed on the House floor after casting a vote and died two days later. Well, once a public servant, always a public servant.

William Howard Taft - From President to Supreme Court Justice

Most former presidents take a step back from government, but William Howard Taft went in the opposite direction. After serving as the 27th president, he was appointed Chief Justice of the Supreme Court in 1921.

He later admitted that being on the Supreme Court was his true calling, famously stating, "I don’t remember that I ever was president." Taft remains the only person in history to have served in both roles! Talk about an upgrade!

Calvin Coolidge - Presidential columnist

Some former presidents write memoirs, but Calvin Coolidge took it a step further. From 1930 to 1931, he wrote a nationally syndicated newspaper column titled Thinking Things Over with Calvin Coolidge .

His articles covered a range of topics, from politics to everyday life. As it turns out, running a country gives you plenty to write about!

Jimmy Carter - The humanitarian president

If there’s one president who redefined life after the White House, that is Jimmy Carter. In 1982, he founded the Carter Center , a nonprofit organization focused on democracy, health, and human rights.

He has also spent decades working with Habitat for Humanity, personally helping to build homes for those in need. In 2002, Carter’s humanitarian work earned him the Nobel Peace Prize, making him the only former president to receive the honor for efforts made after leaving office. He once said his post-presidency was "more gratifying" than his time in politics. Only logical, right?

Ronald Reagan - A Knight of the Realm

Yes, that’s a literal title. Ronald Reagan didn’t take up a new career after leaving office, but he did receive an unexpected knighthood from Queen Elizabeth II. In 1989, just months after stepping down as president, he was made a Knight Grand Cross of the Most Honorable Order of the Bath.

While it’s a prestigious honor, American citizens aren’t allowed to use the title "Sir," so there was no "Sir Ronald" in the works. Reagan wasn’t the only president to receive this honor; Dwight Eisenhower and George H.W. Bush were also knighted.

Bill Clinton - Grammy-winning storyteller

Bill Clinton has always been a gifted speaker, so it’s no surprise that he won not one, but two Grammy Awards, though they weren’t for playing his famous saxophone. He won Best Spoken Word Album in 2004 and 2005, narrating both a children’s book and his autobiography.

Clinton joins a small but prestigious club of American presidents who have won Grammys, including Barack Obama and Jimmy Carter. His ability to captivate audiences didn’t end with politics; he simply found a new stage.

George W. Bush - From the White House to the Art Studio

After serving two terms as president, George W. Bush discovered a surprising new passion: painting. How about that? In 2012, he began taking art lessons , and by 2013, his paintings were revealed to the public following an email hack.

Bush embraced his new hobby and has since published several collections, including Portraits of Courage , which features paintings of US military veterans. His artwork has been exhibited in galleries, proving that a president can become an artist, too. While politics was his career, painting has become his personal form of expression.

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.

3

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.
