Elvis Presley

Born and raised in Tupelo, Mississippi, with early dreams of music stardom, Elvis lived a short life that was nothing short of a miracle for music . His first career breakthrough came in 1954 when he recorded the single "That's All Right," fusing country, blues, and gospel to create a revolutionary new sound . Elvis’s unique music and tremendous popularity led him to achieve his first No. 1 hit, "Heartbreak Hotel," in 1956.

Elvis’ catalog is packed with absolute classics known and loved worldwide, such as "Can't Help Falling in Love," "Burning Love," and "Jailhouse Rock," among many others. Elvis’ image remains one of the most recognizable symbols of Rock and Roll, and his music inspired countless artists.

Bob Dylan

Bob Dylan is one of those artists whose cultural influence is quite difficult to explain because of how much he has achieved. He’s been frequently credited as the creator of folk-rock and is a member of three different Halls of Fame: the Songwriters Hall of Fame, the Rock and Roll Hall of Fame, and the Nashville Songwriters Hall of Fame.

His music is a defining element of American culture, with memorable classics such as "Blowin' in the Wind," "Like a Rolling Stone," "Knockin' on Heaven's Door," and "The Times They Are a-Changin'." And in 2016, he became the first songwriter to receive the Nobel Prize in Literature "for having created new poetic expressions within the great American song tradition."

Frank Sinatra

Frank Sinatra is the quintessential male vocalist. Who hasn’t sung at the top of their lungs some of his legendary songs like "My Way," "Fly Me to the Moon" or "Strangers in the Night." Born in 1915, Sinatra rose to fame in the 1940s as the lead singer for Harry James and Tommy Dorsey. But he would reach stratospheric heights of fame when he launched his solo career.

Sinatra sold more than 150 million records worldwide, won 11 Grammy Awards, starred in over 50 films, and even nabbed an Academy Award for Best Supporting Actor for From Here to Eternity (1953) . But his greatest achievement goes beyond numbers and metrics; he shaped generations of singers through his unmistakable voice.

Chuck Berry

It’s impossible to talk about Rock and Roll without naming its father, Chuck Berry. With his music, he created the blueprint for the genre , delivering a number of all-time classic songs like "Johnny B. Goode," "Roll Over Beethoven" and "Sweet Little Sixteen."

Chuck Berry’s guitar riffs and his one-of-a-kind live performances went on to define some of the main elements of rock, and his signature "duck walk" became iconic and endlessly referenced in pop culture over the years. A fascinating detail about his music is that "Johnny B. Goode" was selected for the Voyager Golden Record music collection that was sent into space on NASA's Voyager spacecraft in 1977 to represent Earth's culture.

Dolly Parton

3,000 songs written, more than 100 million records sold, and 11 Grammy Awards are just some of the achievements Dolly Parton has racked up throughout her impressive career. Born in Sevierville, Tennessee, Parton went on to become one of country music’s greatest ambassadors .

Her music catalog is filled with gems like "Jolene," "9 to 5," "Coat of Many Colors" and "I Will Always Love You," which gained international recognition when Whitney Houston recorded it for The Bodyguard (1992). Parton famously wrote both "Jolene" and "I Will Always Love You" in one day. She also had a successful Hollywood career and was inducted into the Country Music Hall of Fame and the Rock and Roll Hall of Fame.

Bruce Springsteen

Famously hailing from New Jersey, "The Boss" rose to international fame with Born to Run in 1975 and became the voice of working-class America . Songs like "Born to Run," "Born in the U.S.A.," and "Dancing in the Dark" spoke to everyday people, their hopes, struggles, and the coveted American dream.

Springsteen has sold more than 140 million records worldwide and has won 20 Grammy Awards, an Academy Award, and a Tony Award. He was added to the Rock and Roll Hall of Fame in 1999, and in 2016, he received the Presidential Medal of Freedom. To this day, Springsteen remains one of the most respected American songwriters.

7

Madonna

It’s impossible to make a list of the greatest artists in history without including the Queen of Pop . Madonna was (and is) a sensation. She took the world by storm with Like a Virgin (1984) and transformed pop music by constantly reinventing her image, her music, and her provocative performances.

We all remember her from the MTV era and how she redefined the role of music videos and used them as a platform for artistic expression and cultural commentary. Throughout her successful career, she has reinvented her musical style, transitioning between pop, dance, electronic, Latin, and R&B without losing relevance, selling over 400 million records worldwide.

8

Prince

Few artists in history could ever embody versatility quite like Prince did. An incredibly talented person, he not only revolutionized popular music but also created a whole new style that was his own .

He would write, produce, arrange, and perform much of his music himself, and though he’s best known for his guitar, piano, and vocals, Prince could play more than 20 instruments . An absolute music genius! His album Purple Rain (1984) is one of his greatest and best-selling creations, and it earned him several Grammy Awards and an Academy Award for Best Original Song Score.

9

Michael Jackson

A single white glove, a black fedora, military-inspired jackets, and the moonwalk: Michael Jackson’s visual identity is one of the most recognizable images in music history . From his beginnings as a child in The Jackson 5 to conquering the world as the "King of Pop," Michael’s career is marked by an unparalleled string of hits.

It’s no surprise that his most massive album was Thriller (1982), which still holds the record as the best-selling album of all time , with more than 70 million copies sold worldwide. And his total record sales are over 500 million worldwide.

10

Aretha Franklin

Often hailed as the greatest singer of all time, "The Queen of Soul" started singing gospel music in her father’s church before achieving international fame in 1967 with the release of "Respect," her signature song. Aretha’s powerful voice is unmistakable, and her energy on stage will forever be remembered .

Some of her most famous songs are "(You Make Me Feel Like) A Natural Woman," "Chain of Fools," "Think," and "Freeway of Love." On top of her Grammy Awards and millions of records sold, Aretha became the first woman inducted into the Rock and Roll Hall of Fame and received the Presidential Medal of Freedom in 2005.

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.

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.
