Earthquakes

As if the incredible altitude and extreme temperatures weren't enough, Mount McKinley faces another challenge: earthquakes. Due to tectonic plate activity, this type of natural disaster is common in the area, with an estimated 600 earthquakes of varying strength occurring there each year.

Always dressed in white

The summit of Mount McKinley is always painted white. Even during the warmer months, when grass and plants flourish in the surrounding park, the mountain's upper half remains permanently covered in snow and massive ice formations.

Life thrives

It's not just snow around Mt. McKinley. In the area, you'll find about 160 bird species, 39 types of mammals, 14 kinds of fish, and even one species of amphibian. That's a surprising amount of life for such a cold region.

Super frog

If you're curious about this unique amphibian, here's the answer: it's the wood frog, a tiny species that can survive even the harshest winters. How? By almost freezing its entire body. While the frog's cells don't actually freeze, the fluids between them do. Its heart and lungs stop working until spring returns.

Millions of years ago

There was a time when giant reptiles roamed what is now the Mount McKinley area. In 2005, the first dinosaur footprints were discovered in the area, followed by fossil remains. The region was once home to three-toed theropods (carnivorous dinosaurs similar to Velociraptors) and winged pterosaurs that soared through the skies above.

Harsh weather

If you're a fan of summer, Mount McKinley might not be the best choice for you, as it's famous for its extreme cold. Temperatures at the summit can drop as low as -75.5°F, with wind chills plunging to -118.1°F.

Not an easy task

Climbing McKinley is not for everyone. In fact, it's considered extremely difficult and dangerous due to the harsh weather conditions. On average, only about half of those who attempt the climb succeed.

8

Alone

Mount McKinley is lonely. While that may sound sad, it actually means it's one of the most topographically isolated peaks on Earth. In other words, it's far from any other mountain of similar height, which makes it even more striking and impressive.

9

The first

In 1913, Mount McKinley was successfully climbed for the first time. Walter Harper, a native Alaskan, is credited with the honor of being the first person in history to reach the summit of North America’s tallest peak. He was followed by his teammates: Harry Karstens, Hudson Stuck, and Robert Tatum.

America's "Big 5"

When it comes to mammals, Mount McKinley and its surrounding park are home to what's known as the "Big Five." These are the most powerful mammals in the region: moose, caribou, Dall sheep, grizzly bears, and wolves.

Ancient origins

The Grand Canyon isn’t just old—it’s millions of years older than previously thought. Some rock layers at the bottom date back 1.8 billion years, nearly half the age of Earth itself. While the canyon itself is around 5 to 6 million years old, recent studies suggest parts of it began forming 70 million years ago—during the dinosaur era.

Once an ocean floor

Long before it was a canyon, this region sat beneath an ancient sea. The Kaibab Limestone, the canyon’s top layer, formed from marine fossils left behind as the waters receded 270 million years ago. The presence of coral, shellfish, and even shark fossils proves the area was once home to a thriving ocean ecosystem.

Carved by more than water

While the Colorado River played a huge role in shaping the canyon, other forces were at work. Volcanic activity, tectonic uplift, and even landslides helped carve out its immense depths. Lava flows from nearby volcanoes poured into the canyon, creating layers of rock that tell the story of violent geological change.

The earliest human inhabitants

Humans have lived near the Grand Canyon for at least 12,000 years. The earliest known inhabitants were Paleo-Indians, who left behind stone tools and spear points. Later, the Ancestral Puebloans built cliff dwellings and left behind intricate pottery, proving that this seemingly inhospitable land was once home to thriving communities.

First European encounter

Spanish explorer García López de Cárdenas was the first European to lay eyes on the canyon in 1540. Sent by Francisco Vázquez de Coronado in search of legendary cities of gold, he and his men were shocked by its vastness. They tried to climb down for water but failed, unable to comprehend its sheer scale.

Named a national monument

President Theodore Roosevelt designated the Grand Canyon a national monument in 1908, calling it a place "every American should see." He was instrumental in protecting it from commercial exploitation, setting the stage for its eventual National Park status in 1919.

Hidden caves

The Grand Canyon contains over 1,000 caves, but fewer than 400 have been explored. Some remain completely untouched, preserving prehistoric fossils and evidence of ancient human life. Today, only one cave is open to the public—Grand Canyon Caverns, located nearby in Arizona.

Phantom ranch

Built in the 1920s, Phantom Ranch remains one of the most isolated lodges in America. Located at the bottom of the canyon, it’s only accessible by hiking, mule ride, or rafting. Due to high demand, reservations are awarded through a lottery system.

John Wesley Powell led the first recorded expedition through the Grand Canyon in 1869. With one arm lost in the Civil War, he braved the Colorado River’s treacherous rapids in wooden boats. His journey mapped the canyon’s uncharted territory, proving it wasn’t an impassable wasteland but a geological treasure trove.

10

Forgotten civilizations?

Image: Otacilio Maia

In the 1930s, explorer Emery Kolb uncovered a sealed cave in the canyon containing ancient artifacts and human remains. Some speculated it belonged to a lost civilization, but archaeologists determined it was a prehistoric Native American site. The canyon still holds thousands of undiscovered archaeological sites, adding to its mystery and historical significance.

Most Big Mac burgers eaten in a lifetime

Sure, we all enjoy a delicious burger every now and then, but 34,000? That's the total number of Big Macs a 70-year-old retired prison officer from Fond du Lac, Wisconsin, has consumed in his lifetime. Recently, after eating 728 more burgers throughout 2023, Donald Gorske has extended his world record.

On May 17, 1972, Gorske had his first Big Mac and from then on, he never stopped. Every day, he skips breakfast and goes straight for one burger at lunch and one at dinner, accompanied by fries or fruit. Gorske said he used to drive to McDonald's every day, but since retiring, he buys the burgers twice a week in batches and then heats them up in the microwave. What about you? If you had to choose just one food to eat for the rest of your life, what would it be?

Some use the power of their lungs to run marathons, while others use it to break curious world records. On October 8, 2022, David Rush set out to accomplish a feat that, while unusual, required great precision and breathing control: the greatest distance traveled by a blown pea.

With a mixture of concentration and dexterity, Rush managed to blow a single green pea an impressive 84 feet, 11 inches. What makes this record even more remarkable is that he achieved this distance with a single breath. This accomplishment is just one more in the extensive list of Guinness World Records that the Boise, Idaho, resident has achieved in his lifetime; in fact, in August 2024, Rush became the world's top record breaker with 181 titles.

Largest collection of teddy bears

Not long ago, an American woman named Jackie Miley held the title for the largest collection of teddy bears. In her home in Rapid City, South Dakota, Jackie zealously guarded more than 8,000 teddy bears. The collection consisted of at least one bear representing each of the U.S. states and 29 different countries. She got her first bear during a vacation in 2000, and it wasn't until she reached 3,000 bears that she contacted Guinness World Records.

Unfortunately for Jackie, her record was beaten in 2019 by a Hungarian woman named Istvánné Arnóczki, who owns a total of 20,367 teddy bears. However, as far as stuffed animals go, the United States remains on the podium. In 2024, a 27-year-old from Mascoutah, Illinois, entered the Guinness World Records for having an impressive collection of 1,523 Squishmallows, a brand of stuffed toy launched in 2017 that boasts 3,000 different styles.

Longest birthday

Many of us wish our birthdays lasted a little longer than just 24 hours. Well, one young Hawaii native made that dream come true. On February 3, 2018, Paul Morgan celebrated his 28th birthday in a totally original way: by making it the longest birthday ever recorded. But how did he do it? He simply took advantage of the difference in time zones around the world! In doing so, he extended his special day to a total of 48 hours, breaking the Guinness World Record for the longest birthday in history.

Morgan began his epic celebration in Apia, Samoa, one of the first places in the world to welcome each new day. From there, he flew to Auckland, New Zealand, before heading to Los Angeles, and finally landing in Kauai, Hawaii. This carefully planned trip allowed him to cross several time zones and extend his birthday to twice as long as normal. Clever, huh?

And if we talk about birthdays, we can't miss cake! As we get older, candles multiply, but you'll never guess what the largest number of candles on a cake ever recorded is. In 2016, members of the Sri Chinmoy Center in New York, an Eastern philosophy spiritual group, achieved the world record for the most candles lit on a birthday cake.

They burned 72,585 candles for 40 seconds on a huge cake measuring 80.5 feet long and 2 feet wide. It took 100 volunteers to light them and a couple of fire extinguishers to put them out safely. We are not sure if the attendees were able to eat the delicious vanilla mousse sponge cake after such a blaze, but the video of the feat can be seen on YouTube. As of today, it has already been viewed by more than 220,000 people!

It's not just humans who break world records, animals do too! In March 2023, a four-year-old Charolais cow named Ghost broke a Guinness World Record by performing 10 tricks in just one minute. This record, which might seem more fitting for a dog or a horse, is the sole merit of her owner’s ingenuity, Nebraskan Megan Reimann, who applied horse training techniques, such as positive reinforcement, to teach her a series of amazing skills.

Among Ghost’s incredible talents are her ability to come when called, turn, nod her head, give kisses, and even bow—all in just 60 seconds. The success of the "world's smartest cow" is not only a testament to her intelligence but also to the potential all animals have to learn and perform exceptional feats.

This Guinness World Record is probably the exact opposite of counting sheep to sleep. In the summer of 2007, a resident of Birmingham, Alabama, named Jeremy Harper embarked on a feat that would test both his physical and mental endurance: counting out loud to the number one million without leaving his apartment.

For four months in a row, Harper live-streamed his quest on YouTube, capturing an audience of thousands around the world who tuned in to watch him recite more than 11,000 numbers a day. After 89 long days without breaks, sunlight, or privacy, Harper finally reached his goal and set the Guinness World Record for the highest number ever counted out loud.

Surely, when San Francisco-based cosmetics manufacturer Luis Marcus invented bobby pins in the early 20th century, he never imagined that a hundred years later they would be part of a world record. On July 21, 2021, Dean Banowetz, a California hairstylist, set out to accomplish a feat few would have imagined: placing the most bobby pins in a beard.

With precision and dedication, Banowetz managed to attach a total of 4,831 bobby pins to his own beard, surpassing all expectations and setting a unique world record. This stylist, who was already known as the Hollywood Hair Guy, proved that his skill goes beyond traditional hairdressing techniques, exploring the creative potential of something as simple as a bobby pin.

If humans and animals can break world records, why can't the vegetable world do it too? In August 2007, Scott Robb, a horticulturist from Palmer, Alaska, presented a kale at the State Fair that left everyone open-mouthed with its colossal size: 105 pounds, 14.5 ounces.

This achievement was no fluke but the result of years of perfecting farming techniques and a passion for growing giant vegetables. Robb is no stranger to the world of horticultural records; he also holds titles for growing the heaviest turnip (39.2 pounds), the heaviest kohlrabi (nearly 97 pounds), and the heaviest green cabbage (138.25 pounds). Robb's dedication has made Palmer, Alaska, a benchmark for gardening enthusiasts and Guinness World Records.

Eric Kilburn Jr., a 16-year-old from Michigan, has stamped his footprint in the 2025 Guinness World Records book—literally! With feet measuring 13.50 inches and hands just over 7.4 inches, Eric holds the title of "largest hands and feet on a teenager".

His shoe size is an impressive 23 American , while the average for an adult male typically ranges from 8.5 to 9. Before he rose to fame, his mother faced challenges having to get shoes custom-made for him; they cost more than US$ 1,500 a pair. Fortunately, after Eric’s story went viral, brands like Puma and Under Armour offered him custom shoes.
