The steaming, multicolored circle of the Grand Prismatic Spring is one of the most hypnotic and unique sights in the U.S. Part of Yellowstone National Park, this hot spring is the largest in the country and the third-largest in the world, measuring 370 feet wide and 160 feet deep.

Its vibrant colors, ranging from deep blue in the center to fiery red and orange at its edges, are unlike anything we see in nature every day. Minerals and microbes are responsible for these hues, with water temperature causing the pigments to fluctuate . The spring owes its existence to geothermal activity driven by Yellowstone's underlying magma chamber and is located in the Midway Geyser Basin.

One of the reasons why Fly Ranch Geyser is unique in the world is that it was formed after a human accident . This technicolor geothermal geyser, located on the Fly Ranch property in the Hualapai Geothermal Flats of Washoe County, Nevada, wasn’t there before 1916.

In 1916, while drilling a well for irrigation in the area, workers struck near-boiling geothermal water, leading to the creation of the first geyser. Decades later, in 1964, a geothermal energy company drilled a second well nearby, which caused the emergence of the Fly Geyser we know today. It has been spouting water into the sky ever since, forming several cone-like vents atop a mound that continues to grow.

Devil’s Kettle

Where does the water from the Brule River go when it falls? For a long time, this was a mystery. Located in Judge C.R. Magney State Park near Grand Marais, Minnesota, along the North Shore of Lake Superior, the river is famous for its unusual split: one half flows downstream, while the other plunges into a seemingly bottomless hole .

This waterfall has baffled visitors and scientists for years because objects thrown into the "kettle," such as logs and ping-pong balls, appeared to vanish without resurfacing. This fueled theories of underground rivers or deep caverns beneath the falls. The mystery was solved recently when hydrologists discovered that the water entering the kettle resurfaces downstream . The kettle's strong currents explain why objects thrown in don’t resurface; they are broken apart and held underwater, functioning like a natural washing machine.

Mono Lake Tufa Towers

These unique limestone formations, known as the Mono Lake Tufa Towers, emerge from the salty, alkaline waters of Mono Lake , fed by underwater springs. Located in eastern California, near the Sierra Nevada mountains and about 13 miles east of Yosemite National Park, they are a striking natural wonder.

These tufa towers rise dramatically from the water. How were they formed? Mono Lake has no outlet, so its high alkalinity and salinity caused minerals to accumulate over time. This unique environment supports an ecosystem of brine shrimp, alkali flies, and migratory birds. To give you an idea, the lake’s salinity is more than twice that of the ocean, which means you could float effortlessly in its waters, as many visitors do.

If you find a diamond here, you get to keep it—this is the only diamond-bearing site in the world where that's possible. Open to the public for mining , the Crater of Diamonds is a 37.5-acre field located near Murfreesboro, Arkansas. It marks the eroded surface of a volcanic pipe composed of lamproite, a rare volcanic rock.

Visitors sometimes find diamonds of various colors, including white, yellow, and brown, along with other gems like amethyst and garnet. It was here that the "Uncle Sam Diamond" was found, the largest diamond ever dug out in North America, weighing 40.23 carats. Diamonds were first discovered here in 1906 when a local farmer found unusual crystals on his land, which sparked a minor diamond rush.

Rocks that look like flowing water: Antelope Canyon is a famous and breathtaking slot canyon in northern Arizona. It consists of two main sections: Upper Antelope Canyon (a.k.a. Tsé bighánílíní, or "the place where water runs through rocks") and Lower Antelope Canyon ( Hazdistazí, or "spiral rock arches").

The canyon was formed over millions of years as flash floods and desert winds eroded the Navajo Sandstone. Even today, seasonal flash flooding continues to shape and carve the canyon’s mesmerizing features. Its surreal, wave-like formations in shades of orange are a favorite subject for photographers and tourists from all over the world.

The Petrified Forest National Park in northeastern Arizona boasts one of the world's largest and most vibrant concentrations of petrified wood . The park, part of the Painted Desert, is located between the Apache and Navajo Counties.

Most of the wood found there is from ancient conifer trees that date back about 225 million years to the Late Triassic period. These trees were swept into river systems, buried by sediment, and transformed into stone through a process called permineralization . The park also features a wealth of fossilized remains of ancient animals, including early reptiles.

The Devils Tower stands alone, protruding dramatically from the plains. Considered sacred by Native American tribes, it was originally called "bad god’s tower," a name that eventually evolved into its current form. Located in northeastern Wyoming, this igneous rock monolith soars 867 feet above its base.

It was designated the first U.S. National Monument by President Theodore Roosevelt in 1906. Geologists agree that Devils Tower was formed through the intrusion of magma into sedimentary rock layers about 50 to 60 million years ago. Today, climbers from around the world are drawn to its sheer walls, though climbing is prohibited in June to honor Native ceremonies.

The Wave

The Wave is a visually stunning sandstone formation located in the Coyote Buttes North area of the Vermilion Cliffs National Monument. Known for its hypnotic, swirling bands of red, orange, and yellow, its delicate ridges are so easily damaged that even one misplaced footstep could ruin the beautiful patterns.

Approximately 185 million years ago, this area was a vast desert covered in dunes. Over time, layers of sand were deposited, compacted, and cemented, forming this Navajo sandstone shape. Unfortunately, The Wave is only accessible by a challenging hike that requires a permit, due to the fragility of its ecosystem and high demand from visitors. With less than 5% of applicants obtaining a permit each year, it is one of the most exclusive hiking destinations in the world.

The Kasha-Katuwe Tent Rocks National Monument, located in northern New Mexico, displays a unique landscape of tall, cone-shaped rock formations. These "tent rocks," composed of pumice and tuff, are known as "hoodoos." They are natural formations ranging from a few feet to approximately 90 feet tall.

The name "Kasha-Katuwe" means "white cliffs" in the Keresan language of the Cochiti Pueblo. Hiking trails, such as the Slot Canyon Trail, offer visitors the opportunity to explore the cones up close while walking through dramatic, narrow canyons.

A song born from the battle

Image: Benjamin Faust

Our anthem was written in mid-September 1814 by Francis Scott Key. But what was it that brought those words to his mind? Well, the lyrics were inspired by the sight of the American flag flying after the British navy was defeated at the Battle of Baltimore.

Key penned the words while observing the conflict at Fort McHenry during the War of 1812. Originally, the anthem began as a poem, not as a song.

It celebrated the fort’s resilience, symbolizing hope for a young nation. Key’s words quickly gained popularity and were eventually set to the tune of an old British song. Little did he know, it would go on to become the anthem we sing today.

2

What’s in a name?

Image: Joshua Woods

Considering what we said before, it’s logical to think The Star-Spangled Banner wasn’t the original title, do you know what it was?

Key’s poem was originally titled "The Defence of Fort McHenry," a clear reference to the conflict that served as his inspiration.

It wasn’t until October or November of 1814, when the first sheet music was printed, that the title changed to the more poetic "The Star-Spangled Banner."

The new name broadened its appeal, allowing it to reach a larger audience who quickly embraced it. It was a name that spoke not just to the battle, but to the pride of the entire nation. This small change made a big difference in how the song was received.

A song for all languages

Image: Etienne Girardet

You probably already knew part of these details, but what about this one? Did you know the anthem was translated into German?

During the Civil War, Key’s anthem found a new life: Union supporters translated it into German to recruit German-speaking volunteers for the militia.

That was just the beginning, but it certainly wasn’t the last time it was translated. Over the years, the song has been translated into more than a dozen languages, making it accessible to Americans from diverse backgrounds. This highlights the anthem’s flexibility, which adapts to the times and reaches new groups. After all, freedom and perseverance aren’t exclusively American traits, don’t you think?

Baseball’s favorite tune

Image: Wade Austin Ellis

We are all very much used to starting important ceremonies or sporting events by proudly singing the national anthem, but, as you can imagine, there was a first time for that too. Do you know about it?

"The Star-Spangled Banner" made its debut at a sporting event in 1862 during the opening of a baseball stadium in Brooklyn, New York. This marked the first time it was played at a professional game.

Its connection to sports grew stronger over the years, and now it’s a tradition to hear the anthem at nearly every major sporting event. It’s the perfect way to kick off the game, uniting fans in a shared moment of patriotism before the competition begins.

Congress made it official… eventually

Image: Joshua Sukoff

The military had already embraced it as an inspirational song, and it had become a tradition to play it at sporting events, but it wasn’t really official until Congress said so and that didn’t happen until 1931. What about that?

The process wasn’t simple, either. Congress debated the decision, facing opposition from various groups—Prohibitionists, pacifists, and even music teachers—but we’ll explore those details in the next section.

Alternatives like "America, the Beautiful" were suggested, but in the end, Key’s song won out. President Herbert Hoover signed the act, and the rest was history: we finally had a national anthem!

It’s not easy to sing!

Image: Laith Abuabdu

Remember we said teachers were against it? Can you imagine why? On their side, one of the main complaints about "The Star-Spangled Banner" was that it’s too difficult to sing . And we have to hand it to them, the anthem is notoriously hard to perform.

In terms of scales, the original melody spans an octave and a fifth, a range that challenges even professional vocalists. This explains why many groups struggle with the anthem during public performances. How many can say they’ve truly mastered it—are you one of them?

In any case, the tune, originally a British drinking song, wasn’t designed for mass sing-alongs. No wonder it’s become a patriotic rite of passage to attempt singing it!

Women fought for its adoption

Image: Library of Congress

Although it’s not always mentioned first when narrating our history, women have been instrumental in many key moments, and the story of "The Star-Spangled Banner" is no exception.

Women played a significant role in pushing for the anthem’s adoption as the national anthem, how so? The Daughters of the War of 1812, a patriotic women’s organization, were among the most vocal advocates. While some groups opposed it, this organization was very much in favor of it.

Their activism helped build momentum for the 1931 legislation that ultimately led to the anthem’s adoption. In an era when political opportunities for women were limited, this cause offered them a platform to engage in national issues. They succeeded, of course, because persistence pays off!

There is no "official" version

Image: Alessio Fiorentino

This might sound far-fetched, but it doesn’t mean there are alternate lyrics to our anthem. Rather, there’s no single, official version of "The Star-Spangled Banner." While various states have tried to legislate performance styles and etiquette, there isn’t a definitive version set in stone.

This flexibility has allowed for creative interpretations, ranging from traditional orchestral performances to more modern adaptations, depending on the context and the event.

And even if it would be nice to have an official version, this gives everyone the possibility to bring new aspects to our national hymn!

Jimi Hendrix’s legendary performance

Image: Aditya Wardhana

Proof of what we just said, that the lack of an official version gives place to create amazing new interpretations is Jimi Hendrix’s legendary performance. The psychedelic rock guitarist brought a fresh, rebellious spin to "The Star-Spangled Banner" when he performed it at the 1969 Woodstock Festival . While many are familiar with his electrifying Woodstock rendition, Hendrix actually performed the anthem in concert many more times, over 60 times to be specific.

His interpretation added a new layer of meaning, capturing the turbulent spirit of the era. And even though not everyone liked it, no one can deny that, given the context, it was a powerful message!

Do you know the four verses?

Image: Towfiqu barbhuiya

Most of us are familiar with only the first verse of "The Star-Spangled Banner," but did you know the anthem actually has four verses ?

Now, four verses were enough and we can understand that tradition is to sing only the first due to time constraints. But, as it turns out, in 1861, Oliver Wendell Holmes Sr. added a fifth verse, advocating for the end of slavery.

While the additional verses are rarely sung, they tell a richer story of American values and challenges. So, even if you never sing it, you can read the full version and enjoy learning about American ideals!

Anchisaurus

Anchisaurus is one of the first dinosaurs discovered in American territory, although it was not correctly identified at the beginning. The first fossil of this herbivore was found in East Windsor, Connecticut , in 1818, but it was then believed to be part of a human skeleton. In subsequent years, other specimens of this species were uncovered in the area.

It measured 8 to 20 ft in length and lived 210 million years ago in the Portland Formation, Northeastern United States. In the late Triassic and early Jurassic periods, the Connecticut Valley was a dry, steep depression, and it was possible to pass from here to the east and the center of what is now Africa. This explains why some dinosaurs lived both in America and other continents.

Triceratops

Image: photo_steff

One of the most iconic dinosaurs found in America is the Triceratops, a herbivore that lived 70 to 65 million years ago, right at the end of the Age of Dinosaurs, in the Late Cretaceous. Its name derives from Greek and means "face with three horns". One of the largest horned dinosaurs**,** it stood around 7.5 ft tall and weighed about 5 rhinoceroses, the equivalent of 10 tons.

Fossils of this dinosaur have been found in abundance in the Hell Creek Formation in Montana and South Dakota. No fossils of this dinosaur have been found on any other continent. Triceratops has been the state dinosaur of Wyoming since March 1994.

Allosaurus

Allosaurus was one of the largest carnivores of the Jurassic period and its remains in the United States have been found mainly in the Morrison Formation, which covers states such as Colorado, Utah, and Wyoming. It lived 155 to 145 million years ago in North America, Africa, Australia, and possibly China. Also, did you know that the Allosaurus fragilis is the state fossil of Utah?

This bipedal dinosaur was an agile hunter with powerful jaws and sharp teeth. It was a theropod, not as huge as the largest carnivore, Tyrannosaurus rex, but just as fearsome. Allosaurus was bigger than an elephant and heavier than a rhino. Its name means "different lizard" due to its rare concave vertebrae.

4

Stegosaurus

Image: ariesa66

Another inhabitant of the Morrison Formation was the Stegosaurus, famous for its dorsal plates and spines on its tail, which it used for defense. Stegosaurus used to walk on all fours, grazing on low vegetation. Its head was perfectly adapted to this way of feeding. It was first described in 1877 by Yale paleontologist Othniel Charles Marsh, and its name means "roof(ed) lizard".

This Jurassic herbivore has been discovered in several states in the western United States. Scientists have found many fossils, showing that it was a very common creature for 10 million years, despite its tiny brain, small head, and useless teeth. The discovery of the Stegosaurus has helped them better understand the anatomy and behavior of armored dinosaurs.

Tyrannosaurus rex

Image: Elly Enn

Is Tyrannosaurus rex the most famous dinosaur on the planet? Portrayed by pop culture to the hilt, this formidable predator is known for its gigantic size, razor-sharp teeth, and bipedal posture. However, its popularity has a logical explanation. T. rex is also one of the best-represented dinosaurs in the fossil record, with several complete specimens discovered, particularly in the states of Montana, South Dakota, and Wyoming.

Based on bones found in the late 19th century, paleontologist Henry Fairfield Osborn recreated the first drawing of this gigantic creature. He named it Tyrannosaurus rex, meaning "tyrant lizard king," because it is believed to have been the most dangerous dinosaur and the largest land carnivore of all time. Although it is estimated that up to 1.7 billion T. rex dinosaurs lived on Earth, only about 30 nearly complete skeletons have been found. Think about that!

Deinonychus

Image: Steve Wrzeszczynski

This small but ferocious theropod lived during the Cretaceous period about 115-108 million years ago. Deinonychus is known for its sickle-shaped claws on its feet, used for hunting. Its name, unsurprisingly, means "terrible claw". Like all bipeds, it moved only on its hind legs and is believed to have been able to run at 25 miles per hour: more than the average Olympic champion.

Deinonychus fossils were found in Utah, Oklahoma, Montana, and Wyoming, in rocks of the Cloverly Formation and Antlers Formation. The study of this species, beginning in the 1960s, revolutionized the way scientists thought about dinosaurs, providing fascinating new insight into smaller predators.

Ankylosaurus

Image: mdherren

Ankylosaurus is one of the best-known armored dinosaurs, which lived at the end of the Cretaceous period. It had bony protrusions on its head and all over its body as protection against the teeth and claws of predators. The armor was made up of small plates of bone welded together, constituting a shell as effective as that of turtles.

This gigantic herbivore roamed the jungles of North America about 68-66 million years ago, almost as well protected as a modern tank. The first specimen of Ankylosaurus was found in 1906 in the Hell Creek Formation, near Gilbert Creek, Montana. Other fossils of this species were discovered in other parts of Montana and Alberta, Canada, in the following years. However, to this day, it has not been possible to obtain a complete skeleton.

Hadrosaurus

Image: Jordyn St. John

The first Hadrosaurus fossils were discovered by William Parker Folke, an amateur paleontologist, in 1838 in Haddonfield, New Jersey. The excavation site, known as the Hadrosaurus foulkii Leidy site, is now a National Historic Landmark. Hadrosaurids are known for their duck-billed mouth, with a powerful jaw containing several rows of teeth for chewing all kinds of leaves.

In 2004, scientists found a mummified Hadrosaurus specimen in North Dakota. This fossil is extremely unusual and valuable, as dinosaur soft tissue including skin and muscle is rare. This find allows us to learn more about this species and how they lived 67 million years ago.

9

Diplodocus

Image: michaelwedermann

Diplodocus means "double beam" and is so named because of the double bones in its tail. This was one of the longest animals on earth. It was about 79-85 ft long, 15 ft high, and weighed 15 tons. It could reach the tops of towering trees for food, and its small head allowed it to forage in vegetation where few other dinosaurs could reach.

Although some Diplodocus fossils were discovered earlier near Cañon City, Colorado, the most notable find came a few years later. In 1899, Funded by Scottish-American steel tycoon Andrew Carnegie, members of the Carnegie Museum of Natural History found a well-preserved Diplodocus skeleton in the Morrison Formation of Sheep Creek, Wyoming. With these fossils, the museum created a composite mount that became very popular and even got to tour the world.

Apatosaurus

Image: Cup of Couple

Apatosaurus is one of the best-known sauropods that inhabited North America during the Jurassic period. These herbivorous giants, with their long necks and tails, have also been discovered in the Morrison Formation, mainly in Colorado and Utah. It is believed to have lived 150 million years ago, at the end of the Jurassic period.

Apatosaurus could reach 69-75 ft in length, 20 tons in weight, and was one of the largest sauropods. It had a long neck containing 15 huge bones supported by powerful muscles that allowed it to feed on the leaves of the tallest trees. Perhaps this dinosaur sounds familiar. It has been the inspiration for numerous beloved animated characters: Littlefoot from The Land Before Time and Arlo and Poppa Henry from Pixar's The Good Dinosaur are Apatosauruses.
