If you’ve ever seen a cattail and thought it looked kind of yummy, you were on the right track! Cattails grow abundantly in marshy areas across the U.S., and nearly every part of this plant is edible. Often called the "supermarket of the swamp," cattails are incredibly rich in carbohydrates and are a highly versatile food source. These plants not only provide nutrition but also materials for shelter and fire-starting, making them a top resource for wilderness survival in America.

The roots, once cleaned and cooked, have a potato-like quality and can also be dried and ground into flour. Impressively, they even outperform potatoes in starch yield per acre. Young shoots are edible as well, offering a fresh bite when raw or a tender taste when boiled, much like asparagus.

Dandelions

Often dismissed as a pesky weed, dandelions are actually among the most nutritious plants you can find in the wild. In fact, dandelions are considered even more nutritious than broccoli or cabbage! Every part of the dandelion is edible, from the leaves to the roots. With a taste and texture similar to chicory, the leaves are packed with vitamins A and C and be eaten raw in salads or cooked like spinach.

The bright yellow flowers can also be used to make tea, while the roots can be roasted as a coffee substitute. Dandelion tea is loaded with powerful antioxidants, including beta-carotene and polyphenols, and studies suggest it may benefit heart health.

Wild Asparagus

Who knew you could harvest your own asparagus in the wild? Wild asparagus grows across much of the U.S., particularly in moist, sunny areas. While it looks similar to its cultivated cousin, wild asparagus tends to be thinner and tougher. When foraging, look for young shoots, which are more tender and can be eaten raw or cooked.

Like its commercial counterpart, wild asparagus is high in fiber and vitamins, offering a nutritious snack or even a potential side dish in a survival situation.

Acorns

You’re likely already familiar with acorns, the nuts of oak trees. Found abundantly across the U.S., particularly in forests and woodlands, these wild nuts are indeed edible after some processing. Acorns contain bitter tannins, which can be toxic and need to be removed by repeated boiling or soaking in water.

Once safe to eat, acorns can be either roasted or ground into flour. Though they don’t taste like much, they’re packed with carbohydrates, fats, and proteins. Historically, acorns were a staple food for Native Americans and ancient cultures worldwide, proving their value as a survival resource.

Cactus (Prickly Pear)

In the arid landscapes of the American Southwest, prickly pear cacti offer both nourishment and hydration. The pads (nopales) and the fruit (tunas) are not only edible but are also staples in Mexican cuisine.

The cactus fruit, known as a prickly pear, is super sweet and can be eaten raw right off the plant. Depending on ripeness, the flavor ranges from mildly sweet to syrupy. Packed with vitamin C and water, prickly pear cacti can be a true lifesaver if you find yourself stranded in the desert.

Wild Onions

Wild onions grow widely across the U.S., thriving in fields, forests, and even backyards. Their bulbs, stems, and leaves are all edible and can be used just like store-bought onions to add flavor and nutrition to any meal. But foragers, beware—there’s an important distinction to keep in mind!

A highly toxic lookalike called death camas can be easily mistaken for wild onions, and as its name kindly suggests, it can have potentially lethal effects if consumed. The easiest way to tell them apart? Wild onions have a strong onion scent, while death camas has no odor. When in doubt, always trust your nose. That being said, unless you are 100% confident in your ability to identify wild onions, it’s wise to consult an expert or avoid foraging them altogether.

Pine Nuts

Pine trees are scattered across America, and their seeds—pine nuts—are a nutritional powerhouse. These small seeds, found inside pine cones, are rich in fats and proteins, making them a concentrated source of energy. In fact, pine nuts have sustained Native American tribes for centuries.

While they are labor-intensive to harvest, the effort is worthwhile. Packed with calories and bursting with flavor, they are an abundant and reliable food source. But it doesn't end there—surprisingly, most parts of a pine tree can be consumed, including the bark, needles, cones, and resin, either as food or for medicinal purposes.

8

Chicory

Chicory is often found along roadsides and in open fields throughout the U.S. The plant is recognizable by its bright blue flowers, and while its leaves can be eaten like lettuce, its roots are also useful—they can be roasted and used as a coffee substitute.

During the American Civil War, soldiers used chicory to stretch their coffee supplies, and even today some beer brewers occasionally use roasted chicory to add a bitter flavor to stout varieties.

Blackberries

Who hasn't enjoyed picking a few blackberries during a walk? Blackberry bushes thrive across the country, especially in sunny, open areas. These delicious berries are loaded with vitamins C and K, along with fiber, making them an excellent survival food when in season. Additionally, their leaves can be brewed into a soothing tea.

Wild raspberries and strawberries are similarly plentiful in the American backcountry. Their unmistakable appearance and sweet flavor make them a great choice for novice or inexperienced foragers to safely enjoy nature’s pantry.

10

Clover

Who knew that stumbling upon a clover patch could bring more than just good luck? Clover grows abundantly across the U.S., from lawns to meadows, and both its leaves and flowers are edible. The flowers are often dried to make tea, while the leaves can be tossed directly into salads or soups an added nutritional boost.

Rich in protein and minerals, clover has historically served as fodder for livestock, but it can also provide essential nutrition for humans, especially in a survival situation! Its versatility certainly makes it a valuable addition to any forager's repertoire.

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.

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.
