1

Montpellier, Vermont

Montpellier is the smallest state capital in the United States, with only about 8,000 residents along the Winooski River. Instead of traffic jams and towers, you get shops, quiet streets, and a gold-domed Capitol rising above the roofs .

Founded in the late 1700s and named after a city in France, Montpellier still feels more like a New England village than the seat of power that it is.

2

Pierre, South Dakota

Pierre, South Dakota’s capital, is one of the quietest capitals in America , with only around 14,000 residents. It sits high on the bluffs of the Missouri River, where prairie hills roll into wide water and sunsets.

Life here runs at a slower pace than in most capital cities. Government buildings share streets with modest homes, fishing spots, and family-run shops.

3

Augusta, Maine

Maine’s capital is a compact city on the banks of the Kennebec River. With a population well under 20,000 , it trades towering skylines for church steeples, brick storefronts, and a tidy state house.

The city’s roots go back to colonial trading days, and that history shows in its older neighborhoods and riverside mills. Museums, offices, and small coffee shops occupy most of the city’s center.

4

Frankfort, Kentucky

Frankfort, the capital of Kentucky, sits in a river valley surrounded by grass hills. With only 28,000 inhabitants, it’s smaller than many nearby college towns , and keeps a relaxed pace even while housing the ornate state capitol and many of the state’s main offices.

Old brick buildings, historic bourbon distilleries, and close neighborhoods give Frankfort a cozy, walkable feel. On workdays, lawmakers and staff share streets with locals grabbing lunch.

5

Helena, Montana

Montana’s capital began as a gold rush camp in the 1860s and never became a huge metropolis . Today, it remains a mid-sized mountain town, with 33,000 inhabitants, historic brick blocks, steep hills, and the state capitol dome.

Trails and open land sit only minutes away from government buildings, so hikers and cyclists mix with office workers at day’s end.

6

Juneau, Alaska

The remote capital of Alaska is one of the few state capitals that you cannot reach by road . It can only be reached by air or sea. Wedged between steep mountains and icy waterways, it remains relatively small, with a population of 31,000 individuals.

Cruise ships, fishing boats, and floatplanes share the waterfront with government offices and houses on the hillsides. Glaciers, forests, and whales are never far away, making this capital city an incredible place to live.

7

Dover, Delaware

With a population of around 39,000, Delaware’s capital keeps the feel of a small colonial town even as it manages modern state business . Streets near the Capitol Square are lined with brick homes, churches, and public buildings that date back to the American Revolution.

Instead of a dense downtown, Dover offers broad streets, open lawns, and local shops that serve residents more than tourists.

8

Annapolis, Maryland

With 40,000 individuals, Annapolis, Maryland’s capital, proves that a city can be small in size and big in history . Narrow streets wind past eighteenth-century houses, brick taverns, and the domed state house that once served as the nation’s capital.

Its harbor holds sailboats, crab boats, and U.S. Naval Academy midshipmen more often than commuters. Coffee houses, galleries, and waterfront benches make Annapolis feel more like a relaxed resort town than a state capital.

9

Jefferson City, Missouri

The capital city of Missouri sits above a bend in the Missouri River. Smaller than many of the state’s other cities, it is the home of 42,000 individuals. It trades sprawl for tidy neighborhoods, a compact downtown, and a tall capitol overlooking the water .

Named for President Thomas Jefferson, the city balances government workdays with a slower Midwestern rhythm.

10

Concord, New Hampshire

New Hampshire’s capital is a modest New England city where church steeples and a granite state house rise above low-rise streets. With a population of 44,000, it’s smaller than many capitals, and it keeps rush hour brief and downtown walkable.

The city’s history stretches back to colonial days, and older buildings still frame the main streets. Concord also hosts civic events, shops, and offices that keep it lively, mixing a hometown feeling with the grandeur of a state capital.

11

Charleston, West Virginia

West Virginia’s capital sits where the Elk and Kanawha Rivers meet, backed by lush green hills. With 45,000 individuals calling it home, it is smaller than many people expect , with neighborhoods climbing the slopes and a gold-domed Capitol reflecting in the water below.

Coal country history, riverfront parks, and a modest downtown give Charlestown a charming regional flavor. Commuters share roads with barge workers and weekend fishermen, and the city’s size makes government feel close to everyday life.

12

Harrisburg, Pennsylvania

The capital of Pennsylvania is modest in population compared with its big neighbors, like Philadelphia and Pittsburgh . It "only" has about 50,000 inhabitants. Its green-domed Capitol can be seen from afar, in the skyline of mid-rise offices and row houses along the wide Susquehanna River.

Once a major transportation crossroads, Harrisburg still feels more manageable than many urban centers. Riverfront walkways, historic districts, and nearby small towns keep this capital’s rhythm comfortable.

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.
