There was gold in them there hills…
The red clay formations called Las Médulas owe their angular character not to the shaping hands of nature but to those of gold miners—and not grizzled "49ers in grubby flannel and overalls, but 1st-century excavators clad in tattered tunics. When gold seams were discovered here in what"s now northern Spain, the Romans who controlled the region created a clever system of tunnels and canals under the hills, through which they channeled water from nearby streams to build pressure that cracked away huge chunks of clay.Desktop Version
Welcome to the Alien Egg Hatchery
Welcome to the Alien Egg Hatchery
The otherworldly rock formations in the Bisti/De-Na-Zin Wilderness inspired some creative names—such as the "Alien Egg Hatchery" seen in this photo. More than 70 million years ago, this desert was a tidal swamp along the shore of the long-evaporated Western Interior Seaway that once bisected North America. A diverse array of sediment and rock was deposited by the waters, and after the seaway retreated, the rocks remained.Desktop Version
Happy Mother s Day
Happy Mother s Day
Zebras can walk within 20 minutes of being born, but they still need help from mom. On Mother"s Day, we"re looking at a Burchell"s zebra mother and foal. For the first two days after the foal is born, the mother will keep it close by and limit contact with other zebras, so the foal gets to know her by sight, smell, and sound. Over the next year, the foal will follow its mother, learning what to eat, where to migrate in the dry and rainy seasons, and how to avoid predators. Those might not be the exact skills your mom taught you, but she surely played a part in your survival and growth—so be sure to wish her a happy Mother"s Day today.Desktop Version
Mount Logan in Yukon, Canada
Mount Logan in Yukon, Canada
Today we"re visiting Canada"s tallest mountain, the 19,551-foot-high Mount Logan, which is part of the St. Elias Mountain range. Located in Yukon, the smallest and westernmost of Canada"s three territories, this majestic peak is also the second tallest in North America—only Alaska"s Denali is taller.Desktop Version
Mont-Saint-Michel
Mont-Saint-Michel
Rising majestically out of the bay, Mont-Saint-Michel is once again a true island, at least during high tides. A crude, elevated causeway built in the 19th century once connected Mont-Saint-Michel to the mainland, allowing visitors to walk across to the spectacular rock. But in 2014, the causeway was removed and replaced by an elegant, curving bridge above the tidal flats. Now water flows freely around the monument at high tide, making the tiny island fortress a real island for the first time in more than a century.Desktop Version
A swim in the sky
A swim in the sky
A lap in the Sky Pool may have you holding your breath, and not just because you"re underwater. With the streets of London looming 10 stories down, the view through the pool"s clear bottom is a bit freaky to all but the fearless. But swimming here is a one-of-a-kind experience, and for some lucky residents of these twin apartment blocks near the US Embassy, a convenient way to pop in on neighbors the next building over.Desktop Version
A history of Vinland
A history of Vinland
It’s Leif Erikson Day, a day to learn about, and marvel at, the story of this Viking explorer, born in Iceland and thought to have set foot on the North American continent a good 500 years before Christopher Columbus. Want proof? Head to Newfoundland, Canada, where today’s photo was taken. Archaeologists discovered the remnants of a Viking outpost on the island’s north coast in 1960. L’Anse aux Meadows, as it’s now known, is a historic site open to the public, and the only solid evidence that Vikings were the first Europeans to land in North America, which they called Vinland.Desktop Version
A truly American monument
A truly American monument
Sunlight on the Lincoln Memorial highlights not just the ornate detail of the monument, but the variety of material used to construct it. Architect Henry Bacon made sure to use granite, marble, and limestone sourced from states throughout the country. At the time of Lincoln’s presidency, there were only 36 states in the Union, so all 36 of those states’ names are what’s carved into the frieze directly above the columns. Now that we’ve given you a little bump of patriotic pride, remember that it’s Election Day. Did you vote?Desktop Version
High trekking season in Upper Mustang
High trekking season in Upper Mustang
If you’re lucky enough to be one of the thousand or so tourists allowed into Upper Mustang each year, spring and autumn are the best times for trekking through this incredibly dramatic landscape. Tucked into a remote region of Nepal, it’s geographically part of the Tibetan Plateau. The area is surrounded by the Annapurna and Dhaulagiri Massifs and marked with deep gorges, terraced fields, and colorfully stratified rock formations. But perhaps most fascinating of all are the sky caves, 10,000 or so caves dug into the sheer walls of valleys in several areas of the district. Some of these man-made caves are thought to be ancient burial chambers; others are richly decorated with valuable Buddhist paintings, sculptures, and artifacts from the 8th to the 14th centuries. Perched over 150 feet above the valley floor, no one is entirely sure how the caves were built, what they were used for, or even how people accessed them.Desktop Version
Citizenship Day and Constitution Day
Citizenship Day and Constitution Day
Today we visit the National Archives in Washington DC, where the US Constitution and the Declaration of Independence are on display, to mark Constitution Day and Citizenship Day. It"s a single day with a dual purpose—commemorating the formation and signing of the Constitution, while also recognizing both naturalized citizens and those born in the US. Ordinarily, many people become naturalized citizens in group ceremonies on this day; on average, about 700,000 people become American citizens each year.Desktop Version
National Hug Day
National Hug Day
Even the toughest predator on the South African savannah can get snuggly, especially on Hugging Day. Founded 35 years ago, this celebration of the embrace is meant to lift spirits during the post-holiday lull, encouraging family and friends to hug each other more often, not only today but every day. So, what are you waiting for? Go hug people!Desktop Version
It s time to fall back
It s time to fall back
While today"s image may look like a scene from the "Doctor Who" TV show, it actually shows workers maintaining Big Ben"s clock face. But like the Doctor, the show"s main character, today we"re all time travelers. This morning we fell back (or will fall back for night owls and insomniacs reading this before 2 AM) in time an hour for the end of daylight saving time. And like changes to "Doctor Who," this shift isn"t without controversy. Since the 1970s, many studies have tried to quantify the advantages or disadvantages that come with falling back and springing forward, but as yet there"s no definitive answer.Desktop Version
From pirate port to nature preserve
From pirate port to nature preserve
Barataria Preserve is one of six distinct locations that make up Jean Lafitte National Historical Park and Preserve in Louisiana. The wetlands and bay at Barataria are tied closely to the history of this portion of the Mississippi River Delta. In the late 1700s, Barataria Bay was where the well-dressed smuggler and occasional pirate Jean Lafitte and his brother Pierre built a port. Far from the nearest US naval base and the prying eyes of customs officials, Barataria offered the brothers a safe place to smuggle in goods they"d stolen from ships in the Caribbean, or sometimes bought on the black market. They then sold the merchandise, mainly to merchants in New Orleans. Jean Lafitte and his comrades also helped to defend New Orleans against the British in the final battle of the War of 1812. These days, he’s chiefly remembered for his heroism in the Battle of New Orleans and for the jobs and goods he provided in the region--the erstwhile pirate is a folk hero of a sort, and famous enough that a national historical park was named for him.Desktop Version
It s World Bee Day
It s World Bee Day
Today we"ve buzzed to Provence, France, to enjoy this scenic view brought to you by bees. These hard-working insects are key pollinators of flowers, like the sunflowers and lavender seen growing here. That’s why beekeepers have strategically placed these hives near the flower crops. Bees are also critical for the pollination of fruits and vegetables—about a third of the food we eat is a result of honeybee pollination. In the US, honeybees, whether tended by beekeepers or living in the wild, pollinate about $20 billion worth of crops every year. That"s a lot of gold—and doesn"t even include their delicious honey. So today on World Bee Day, we invite you to stop and smell the flowers and give a nod to the bees that help color our world.Desktop Version
Holey moley–it’s National Doughnut Day!
Holey moley–it’s National Doughnut Day!
Observed annually on the first Friday in June, National Doughnut Day isn’t a marketing ploy by the American Bakers Association. It actually commemorates the women of the Salvation Army who cared for soldiers serving on the front lines of World War I in Montiers-sur-Saulx, France. After several weeks of inclement weather, the demoralized soldiers’ spirits were lifted by a taste from home. The Doughnut Lassies, as the Salvation Army women became known, are often credited with popularizing the doughnut after soldiers returned home after the war. Later, during the depths of the Great Depression in 1938, Chicago’s Salvation Army began National Doughnut Day as a fundraiser to help those in need. The Salvation Army celebrates National Doughnut Day these days by delivering thousands of doughnuts around the country.Desktop Version
Short-eared owl
Short-eared owl
Silently swooping over the open English countryside in search of its next meal is a short-eared owl, though that"s something of a misnomer. Named for the inconspicuous tufts on top of its head that resemble ears, the owl"s true ears are on the side of its head, hidden by feathers. But those tiny false "ears," which may function as display feathers or camouflage, lend the owl a distinctive appearance, and the short-eared owl is often affectionately called "shortie." Here in England, short-eared owls are seen more frequently in winter, when their numbers are boosted by an influx of continental birds migrating from Scandinavia, Russia, and Iceland.Desktop Version

A notorious gunfight that was incorrectly named
A notorious gunfight that was incorrectly named
The gunfight that occurred here in Tombstone, Arizona, on this day in 1881 has become the stuff of legend. In a 30-second shootout known as the Gunfight at the O.K. Corral, lawmen Virgil Earp, Morgan Earp, Wyatt Earp, and Doc Holliday faced off against a band of outlaws known as the Cochise County Cowboys. Justice was harsh in the Old West. When the dust had settled, three were dead and several others wounded. But most accounts of the event are wrong about one key detail—the location. The shootout actually took place near C. S. Fly’s Photographic Studio, about six doors west of the corral"s rear entrance. We suppose ‘Gunfight near C. S. Fly’s’ doesn’t have quite the same ring to it.Desktop Version

Today, we"re 11,000 feet above sea level in the city of Cusco, in the Peruvian Andes. Cusco is considered the historical capital of Peru, a designation that"s even enshrined in the country"s constitution.

Winter at Valley Forge
Winter at Valley Forge
Valley Forge, Pennsylvania, is the site of the winter encampment of the Continental Army under General George Washington. On December 19, 1777, about 12,000 soldiers and 400 women and children started to build 1,500 log huts where they would live for the next six months. At the time, the British were occupying the patriot capital of Philadelphia, just a day"s march away. Already two and a half years into the war, troops knew the harsh winter would stop the fighting, allowing them to organize and avoid mobilizing for several months. Life, however, was still challenging as they lacked funds for fresh food and clothing. There were no battles at Valley Forge, but nearly 2,000 people died from disease during the encampment.Desktop Version
Flock together for Cousins Day
Flock together for Cousins Day
Are these chicks cousins? Perhaps. Caribbean (aka American) flamingos, like all flamingo species, lay just one egg per year, so chicks of the same size are more likely cousins than siblings. These chicks and their hovering parents are in the Ría Lagartos Biosphere Reserve in the Yucatan Peninsula, a critical nesting colony for Caribbean flamingos. They’re highly social birds that live in colonies of thousands, so they have plenty of opportunities to celebrate Cousins Day today. Here’s to you, cuz!Desktop Version
Nesting season for the leatherbacks
Nesting season for the leatherbacks
This time of year is nesting season for leatherback sea turtles in the Atlantic. After mating at sea, these big mamas—leatherbacks are the largest of all turtles—haul themselves up onto beaches in the same region where they were born. The turtles dig out nests in the sand and lay a clutch of about 80 fertilized eggs the size of billiard balls. They"ll repeat this ritual a few more times before returning to their migratory lives in the open ocean. About 65 days later, turtle hatchlings will start to poke up through the sand and make a dash toward the safety of the sea. But the odds are against them: Only 1 percent of the hatchlings will live to reach sexual maturity, at around 16 years old.Desktop Version

Santorini, Greece
Santorini, Greece
Officially known as Thira, Santorini is perhaps the most famous of all the Greek islands. Located at the southern end of the Aegean Sea, Santorini is part of the Cyclades group of islands and receives about 2 million visitors a year. That"s a lot of adoring attention for a small island (only 28 square miles) of 15,000 residents, and it"s no wonder why. The whitewashed, clifftop villages of Santorini, like Oia featured in this image, are postcard-perfect. And so are the unlimited panoramic views of the azure Mediterranean Sea.Desktop Version
