Havasu Falls, Arizona

Yes, technically, people know about Havasu Falls, but getting there requires permits, careful planning, and a ten-mile hike into the Grand Canyon that'll have your knees filing for divorce. The turquoise water looks Photoshopped, but it isn't—it's caused by calcium carbonate and magnesium that create that otherworldly blue-green glow. Most tourists snap their Grand Canyon photos from the rim and call it a day, completely unaware that this paradise exists below.

Linville Falls, North Carolina

Tucked in the Blue Ridge Mountains, this waterfall drops in multiple tiers through Linville Gorge , nicknamed the "Grand Canyon of the East." The upper falls plunge 12 feet, followed by the lower section, which drops another 90 feet into the gorge below.

Multiple trail options mean you can customize your effort level, from an easy quarter-mile stroll to more challenging overlooks. The best view? Probably Chimney View, which gives you the full dramatic drop and a sweeping view of the gorge beyond.

Potato River Falls, Wisconsin

Potato River Falls sits near the Michigan border in the Northwoods, where many visitors are too distracted by fishing and Friday fish fries to notice the waterfall itself. The falls drop about 90 feet in cascading sections, with observation platforms that make viewing easy —no mountain-goat skills required. The surrounding forest feels wonderfully remote, even though you're only a short walk from the parking area.

Natural Falls, Oklahoma

Yes, Oklahoma has waterfalls, and Natural Falls State Park proves it, dropping 77 feet into a surprisingly lush canyon . The trail to the viewing platform takes about ten minutes, making this possibly one of the best effort-to-reward ratios on this list.

The falls flow year-round thanks to a spring-fed creek, though spring brings the most dramatic water volume. A large amphitheater-like alcove behind the falls provided the backdrop for parts of the 1974 movie Where the Red Fern Grows , if you're into vintage cinema trivia. Visit early in the morning to have the place to yourself and contemplate the geographical surprises America still holds.

Fall Creek Falls, Tennessee

At 256 feet, Fall Creek Falls is one of the tallest waterfalls east of the Mississippi , yet somehow remains less famous than Graceland. Located in a state park of the same name, it's the crown jewel among several waterfalls in the area, meaning you can actually hit multiple cascades in one day if you're feeling ambitious. The main overlook requires minimal effort, but trails wind down to the base if you want the full experience and don't mind plenty of stairs.

Alamere Falls, California

California has no shortage of waterfalls, but Alamere Falls does something truly special: it drops directly onto the beach . This rare "tidefall" spills over cliffs at Point Reyes National Seashore, creating a scene that looks like a screensaver come to life. Getting there requires an 8-mile round-trip hike that's moderately strenuous but manageable for anyone in reasonable shape. The trail winds through coastal forest before emerging onto wind-swept beaches.

The falls flow strongest in winter and spring when California actually gets rain, becoming a mere trickle by late summer. Time your visit right, and you can stand on the beach while 40-foot waterfalls crash onto sand beside tide pools and sea stacks.

Kaaterskill Falls, New York

The Catskill Mountains hide New York's tallest waterfall, a two-tiered, 260-foot cascade that inspired Hudson River School painters back when America was young, and landscape painting was the closest thing to Instagram. Kaaterskill Falls sits just off Route 23A, and the short trail to the base viewpoint feels properly wild. Adventurous types sometimes scramble between the tiers, though this requires caution and a complete disregard for your mother's warnings about safety.

Winter transforms the falls into a frozen sculpture, attracting ice climbers who've made interesting life choices. The surrounding forest looks like something from a fairy tale, all moss and ferns and filtered light.

Bridal Veil Falls, Colorado

Bridal Veil Falls near Telluride claims the title of the state's tallest free-falling waterfall at 365 feet . The waterfall cascades like a lace curtain—hence the name—from a hanging valley, and at the top sits a power plant that's somehow still photogenic. The hike up is steep and challenging, gaining about 1,800 feet over roughly two miles, which sounds reasonable until you remember you're doing this at high altitude.

Cloudland Canyon Falls, Georgia

Georgia surprises people with its waterfalls, and Cloudland Canyon State Park delivers two beauties: Cherokee Falls and Hemlock Falls , accessible via a moderately strenuous trail system. The park sits on the western edge of Lookout Mountain, where the canyon cuts deep into the plateau. Cherokee Falls drops about 60 feet, while Hemlock Falls offers a 95-foot cascade. Both require descending (and later climbing back up) hundreds of stairs, so consider this your ultimate leg-day workout.

10

Fairy Falls, Wyoming

Yellowstone gets all the geothermal glory, but Fairy Falls offers a quieter experience just a few miles from the madness of Old Faithful. At 200 feet, this ribbon of water drops from the Madison Plateau into a peaceful forest clearing . The trail is about five miles round-trip along old fire roads, flat and easy enough for most fitness levels.

Most Yellowstone visitors stick to the main loop, which means Fairy Falls sees only a fraction of the park's three million annual tourists. The falls flow strongest during spring snowmelt, becoming more modest by late summer.

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.
