We’ll start with what many believe to be Alaska’s crown jewel. Formerly known as Mount McKinley, Denali is the highest peak in North America, with a summit elevation of 20,310 feet above sea level. Its height is matched only by its magnificence—a snow-covered wonder adorning the Alaskan skyline.

The name "Denali" comes from the Koyukon Athabaskans, who are native to the region. They referred to the mountain as Dinale or Denali, which is believed to be a Koyukon word meaning "high" or "tall." Over the years, many mountaineers have attempted to reach the peak, with the first successful ascent dating back to 1913.

East of the city of Anchorage lies Chugach State Park , a 495,204-acre state park that houses the stunning Chugach Mountains. However, this park is more than just a scenic landscape; it plays a crucial role in ensuring that the residents of Anchorage have access to safe drinking water.

Chugach State Park is also home to Eklutna Lake, which offers numerous recreational opportunities, including fishing, camping, and hiking. The park supports a diverse array of wildlife, including moose and bears.

Kayak Island

In 1826, Lt. Sarychev of the Russian Navy noticed the peculiar shape of a certain island located in the Gulf of Alaska. Because it resembled a specific type of boat, Sarychev named the island Kayak Island , unaware that he was christening one of Alaska’s most stunning destinations.

Kayak Island is considered historically significant since it was the first place where a non-native set foot in Alaska. Notably, the island was visited by the famed explorer Captain James Cook in 1778. During this visit, Captain Cook left an empty bottle at the base of a prominent tree. Inside the bottle was a message and two pieces of silver gifted to him by the English crown.

Next, we have Kodiak Island , the second-largest island in the United States. Over two-thirds of the island is occupied by the Kodiak National Wildlife Refuge, which protects a diverse range of wildlife, including the Kodiak bear, Roosevelt elk, and Sitka black-tailed deer.

While no entry is allowed to the refuge, the island still has plenty to offer visitors. For example, you can experience the island’s beauty at the Buskin River State Recreation Site, which features camping, fishing, and scenic beaches.

Fjords are a truly unique natural wonder that can only be found in a few places in the world, and Alaska is home to one of the most beautiful of its kind. Located on the Kenai Peninsula, west of the town of Seward, Kenai Fjords National Park is a breathtaking expanse of glaciers, islands, and wildlife.

With a total area of 669,984 acres, Kenai Fjords is relatively small—approximately 90% the size of Yosemite. Regardless, of what this park lacks in size, it more than makes up for in accessibility, diversity, and, above all, natural beauty. It is home to the Harding Icefield, one of the largest ice fields in the United States, as well as an impressive variety of wildlife, including black bears, sea otters, and killer whales.

As the largest American state by landmass, it seems only fitting that Alaska is home to the largest national park in the United States. Wrangell–St. Elias National Park and Preserve encompasses the Wrangell Mountains and a significant portion of the Saint Elias Mountains, including Mount Saint Elias, the second-highest peak in both the United States and Canada.

Besides many species of animals like the grizzly bear and the timber wolf, this park is home to Mount Wrangell and Mount Churchill—two of the largest volcanoes in the region. Not only that, the abandoned buildings of a former copper mining operation within the park have been designated a National Historic Landmark district.

Don’t be surprised by the number of stunning glaciers that made it onto this list—after all, these natural wonders are Alaska’s pride and joy. With that in mind, here’s the first entry in our selection of beautiful glaciers you should definitely visit: Glacier Bay National Park and Preserve.

The park houses 7 glaciers in the park, out of which the Margerie Glacier is probably the most famous. This iconic glacier attracts thousands of tourists each year, with nearly 80% arriving via cruise ships. Not only that, the park also offers several other outdoor activities like kayaking, camping, fishing, and bird-watching.

Located within the previously mentioned Wrangell–St. Elias National Park and Preserve, Hubbard Glacier undoubtedly deserves its own spotlight. This stunning glacier can be found right on the border between Alaska and Canada, with part of it extending into Kluane National Park and Reserve in Yukon.

Hubbard Glacier is primarily visited by tour and cruise ships since it can’t be reached by land. Regardless, experiencing the beauty of this natural wonder requires nothing more than gazing upon its majestic presence.

9

Worthington Glacier

Worthington Glacier holds the distinction of being one of the few US glaciers that can be easily accessed via a paved highway. Located approximately 30 miles east of the city of Valdez, this glacier is truly a sight to behold.

Covering 5,774 acres, this breathtaking glacier was designated a National Natural Landmark in 1968. If you’re planning a visit, consider stopping at the Worthington Glacier State Recreation Site, a comfortable state roadside park that offers a stunning view of the glacier.

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.
