Old Rock Day
Old Rock Day
Today is a day that puts time into perspective. Old Rock Day highlights the vast geological processes that have shaped our world since its earliest eras. In Arches National Park, Utah, Turret Arch—seen through North Window—offers a striking reminder: landscapes can take hundreds of millions of years to assemble. The Entrada Sandstone that forms these arches began as shifting dunes and shallow seas long before erosion carved today"s shapes. Even so, these formations are relatively young. Most rocks on Earth disappear over time because plate tectonics, erosion, and volcanism continually recycle the crust. Only the planet"s ancient continental shields preserve truly old material. Canada"s Acasta Gneiss, about 4 billion years old, is the oldest known rock still rooted where it formed.Desktop Version

Muir Woods National Monument anniversary
Muir Woods National Monument anniversary
Step into the realm of giants. Try embracing a BFG (Big Friendly Giant) as you wrap your arms around a thousand years of wisdom in a single tree trunk. Welcome to Muir Woods National Monument—established on this day in 1908—a majestic hall of coastal redwoods just north of San Francisco. These towering redwoods are the tallest trees on Earth—one here stretches about 258 feet, roughly the height of 43 people stacked head to toe. Most are 600–800 years old, and some have stood for over a millennium, yet they"re still considered "young" for a species that can live for 2,000 years.Desktop Version
Karlovy Vary, Bohemia, Czechia
Karlovy Vary, Bohemia, Czechia
In today"s image, winter settles over Karlovy Vary in Czechia, a pastel valley that built its identity around the hot springs rising through its hills. The eponymous city traces its beginnings to accounts of Charles IV, then king of Bohemia (a historic region of Czechia) and later Roman Emperor, encountering a steaming pool here in the 14th century, an early moment that set this quiet part of Bohemia on the path to becoming a spa retreat.Desktop Version
Plate ice along Lake Superior, Grand Marais, Minnesota
Plate ice along Lake Superior, Grand Marais, Minnesota
When winter tightens its grip on Lake Superior in Minnesota, the shoreline transforms into a landscape of tilted, glass-like shards known as plate ice. Thin sheets fracture under shifting temperatures, then drift and stack as the wind presses them toward land. The result is a field of translucent blues and silvers, catching the light at sharp angles and making the water"s edge appear sculpted rather than frozen.Desktop Version

Its vast hypostyle hall, a space supported by rows of columns, features the famous red-and-white arches shown here. Today, it contains more than 850 columns, many reused from Roman and earlier Visigothic structures.Desktop Version
Boxing Day
Boxing Day
The best thing about Boxing Day is that it doesn"t ask much of you. No big countdown. No dramatic unwrapping. No last-minute dashes for batteries. It"s a rare holiday that says, "Sit down, finish your leftovers, and take a moment." Celebrated on December 26 in the United Kingdom and some Commonwealth countries, it"s a national cool-down after Christmas has done all the heavy lifting. The term goes back to Victorian Britain, when households prepared Christmas boxes for workers and tradespeople—tokens of thanks that ranged from coins to essentials. Churches joined in by opening alms boxes and distributing donations.Desktop Version
A traboule in Lyon, France
A traboule in Lyon, France
In Lyon, France, you don"t just walk through the city—you glide through it. The traboules, a network of hidden passageways threading between courtyards and buildings, turn a simple stroll into a treasure hunt. They were the original shortcuts, allowing residents to dodge rain, carry goods, or move discreetly through the medieval quarters. Today, they"re less about practicality and more about discovery. These passages date back to the fourth century but became essential during the Renaissance, when silk traders used them to shuttle delicate fabrics safely from workshops to the river without braving the weather. Later, during World War II, Resistance fighters used the traboules as escape routes.Desktop Version
Leopard at Etosha National Park, Namibia
Leopard at Etosha National Park, Namibia
If you"ve ever watched a wildlife documentary, you know the moment: the camera pans across a quiet savanna, and suddenly a leopard appears as if it has been there all along. That quiet reveal says everything about how these cats operate. They move with precision, slipping through grass and branches without making a sound. Their build, muscular but lean, helps them climb, sprint, and hide in plain sight. Their rosetted coats? No two patterns match, each serving as natural camouflage from sunrise to moonlight.Desktop Version

Happy Halloween!
Happy Halloween!
Tonight, Halloween casts its spell—and only a few places on Earth carry a mystery quite like Bran Castle in Romania. The fortress was built in the 14th century and has withstood wars, monarchs, and shifting empires. But here, legends speak louder than history. Perched between the regions of Transylvania—renowned for its chilling tales—and Wallachia, once ruled by Vlad III Dracula, the castle evokes a haunting legacy. Vlad"s ruthless reputation inspired Bram Stoker"s 1897 Gothic novel "Dracula." Though the story is not set at Bran Castle, its looming form and persistent rumors of Vlad"s presence blur fact and legend, forever linking it to one of humanity"s most enduring tales.Desktop Version
Celebrating 78 years of Everglades National Park
Celebrating 78 years of Everglades National Park
On Florida"s southern tip lies one of the United States" most unusual landscapes. The Everglades is not a typical swamp or river. It is a slow, shallow sheet of water that drifts south across flat grasslands toward Florida Bay, linking forests, marshes, mangroves, and coastal prairies. This subtropical wilderness supports hundreds of species, including alligators, manatees, and the endangered Florida panther. On December 6, 1947, the United States established the Everglades National Park, protecting over 1.5 million acres and shifting conservation toward preserving entire ecosystems rather than isolated landmarks.Desktop Version

Eurasian otter and pup, Estonia
The clue isn"t the tracks in the snow—it"s the frosted faces peeking out like they"ve just discovered winter. Estonia is one of Europe"s best places to spot Eurasian otters, thanks to its clean rivers, wide wetlands, and snack-filled coastline. This protected species was named Estonia"s Animal of the Year in 2024.

Leshan Giant Buddha, Sichuan, China
Leshan Giant Buddha, Sichuan, China
There are big statues—and then there"s the Leshan Giant Buddha. Carved into a riverside cliff at the confluence of the Min, Qingyi, and Dadu Rivers in Sichuan, China, this statue is an ancient engineering marvel. Construction began in 713 CE under a monk named Hai Tong, who hoped that the Buddha"s presence would calm dangerous river currents that threatened passing boats. He was so devoted that when funding ran out, he reportedly gouged out his own eyes to prove his sincerity. Construction took roughly 90 years and was completed long after Hai Tong"s death. At 233 feet tall, it is the largest stone Buddha in the world. Its shoulders stretch about 92 feet wide, its ears measure nearly 23 feet long, and each foot extends over 28 feet. Drainage channels built inside the statue protect it from erosion, helping explain its remarkable preservation for more than 12 centuries.Desktop Version
Martimoaapa Mire Reserve, Finland
Martimoaapa Mire Reserve, Finland
Today, we step into the Martimoaapa Mire Reserve in Finland, where wide, cold-climate wetlands and peatlands stretch across a landscape shaped over thousands of years. This reserve is more than just mires—it carries layers of history. During Finland"s Prohibition era (1919–1932), smugglers hauled sacks of liquor from Sweden across these bogs, following a "spirits" route that passed through Martimoaapa. Parts of that path can still be traced today. Imagine trekking with a heavy pack over soggy ground—would you have made it?Desktop Version

One loud whoop—and winter suddenly feels awake. These birds migrate from Siberia and the Russian Far East, choosing Japan as their seasonal home because its lakes offer what long-distance travelers crave: open water, steady food, and a safe place to rest.
