A natural monument of unparalleled beauty, painstakingly carved over millions of years by the Colorado River , The Grand Canyon’s layered bands of red rock reveal more than just a part of the history of the land, but also offer a humbling window into deep time and Earth’s origins.

President Theodore Roosevelt himself was one of the foremost advocates for the preservation of the Grand Canyon area , frequently visiting to hunt and revel in its natural beauty. Before the arrival of Europeans, the area was continuously inhabited by various Native American groups, who often dug and carved their settlements directly into the ancient rock.

A geothermal wonderland, home to geysers, hot springs, and bubbling mud pots , Yellowstone is a wildlife haven where bison, grizzly bears, and wolves roam freely amidst its stunning natural features. Moreover, Yellowstone not only holds the distinction of being the first national park in the U.S. but also in the whole world, setting a precedent for conservation laws and standards that would be emulated worldwide.

Interestingly, the Yellowstone Caldera—the volcanic system responsible for the park’s intense geothermal activity—is the largest in North America and is considered a dormant "supervolcano." In the past, large eruptions from this region likely contributed to the extinction of many species, blanketing much of central North America in ash.

The region surrounding the legendary mountain became a National Park in 1917 , and since that time the rugged landscape of the park has been a haven for outdoor enthusiasts, offering unique opportunities for wildlife viewing. The pristine landscape features a diverse mix of forests, deciduous taiga, tundra, and glaciers , preserving a slice of untouched wilderness that highlights the raw, untamed beauty of Alaska.

With its mist-shrouded peaks and verdant forests, the Great Smoky Mountains are one of the most scenic and alluring landscapes of the United States.

A subrange of the Appalachian Mountains, the soothing vistas of lush forests growing above the ancient peaks are often veiled by a hazy blue-ish mist , which gives the name to the region.

One of the world's most famous waterfalls, Niagara Falls is an emblem of America’s diverse natural beauty. Straddling the international border between Canada and the United States, millions of gallons of water cascade over its cliffs every minute , drawing visitors from both nations to marvel at this awe-inspiring natural spectacle.

Formed by the Niagara River, which channels the waters from Lake Erie into Lake Ontario before ending up in the Atlantic, the falls experience a rate of erosion of almost a foot per year. If the erosion continues at this pace, in about 50,000 years the falls will completely erode the remaining 20 miles to Lake Erie and cease to exist.

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.
