China s colorful terraced pools
While the sight of these gorgeous pools may make you want to don a swimsuit and plunge in for a refreshing soak, we don"t recommend it. The water may be fed by underground geothermal springs, but these are no hot springs—the water"s only about 41 F. We"ll take it all in from dry land. The terraced, travertine pools cascade downward for nearly 2 miles. Formed over thousands of years, calcite deposits give the water its unique, and welcoming, turquoise coloration.Desktop Version
Happy trails for the 21st century
Happy trails for the 21st century
We celebrate National Park Service Founders Day today with this photo from the John Muir Trail near Mammoth Lakes in California. The 210-mile trail is so long, to hike it all would take you through three national parks: Yosemite, Kings Canyon, and Sequoia. At 102 years old, the National Park Service continues to do the day-to-day work of preserving our parks ‘for the enjoyment, education, and inspiration of this and future generations.’Desktop Version
Manatee Appreciation Day
Manatee Appreciation Day
Today is Manatee Appreciation Day and, given their sweet and friendly nature, it"s hard not to love them. These gentle giants slowly graze through rivers and coastal waters for up to seven hours a day, eating seagrasses and other aquatic plants. They do have teeth, but fear not, they are flat molars used for grinding up vegetation.Desktop Version

Saint Dwynwen s Day
Saint Dwynwen s Day
Love is in the air on Llanddwyn Island at the southern tip of Anglesey, a much bigger island just off the northwest coast of Wales. Each year on January 25, Cupid aims his arrow toward the people of Wales who celebrate St. Dwynwen"s Day—the Welsh version of St. Valentine"s Day. St. Dwynwen is Wales" patron saint of lovers, although she was rather unlucky in that department after falling head over heels for a man she wasn"t allowed to marry. The 5th-century princess"s heartache led her to dedicate her life to God and pray for true lovers to have better fortune than her own. In return, Dwynwen became a nun and set up a convent here on Llanddwyn.Desktop Version
Desert rose of Qatar
Desert rose of Qatar
International Museum Day brings us to Qatar, a small but wealthy nation on the Arabian Peninsula, surrounded by the waters of the Persian Gulf and bordered by Saudi Arabia to the south. In the capital city of Doha you"ll find its national museum, shown here, which opened in March 2019. This elaborate building was designed by Pritzker Prize-winning architect Jean Nouvel, who sourced his inspiration from the desert rose crystal. Look closely and amid the futuristic interlocking disks of the new museum you"ll see the early 20th-century Old Amiri Palace, once home of the Emir of Qatar, surrounded by a courtyard of palm trees.Desktop Version
A center of antiquity on the Mediterranean
A center of antiquity on the Mediterranean
This bird"s-eye view lets us take in the charms of Ortygia, a small island just offshore from Syracuse, on Sicily"s east coast. Ortygia is considered Syracuse"s "old town" and the historical heart of the city. Two bridges cross the narrow channel that separates Ortygia from Syracuse. Ancient Greeks first colonized this island in the 8th century BCE, and the town is brimming with 2,700 years of history. Walk Ortygia"s web of narrow streets and you"ll see Greek and Roman ruins, medieval Norman buildings, and examples of Baroque architecture as well.Desktop Version
Through an artist s eyes
Through an artist s eyes
If this beautiful view of Grand Teton National Park seems as pretty as a painting, there may be a reason for it. The majestic peaks towering over the landscape include Mount Moran, named for Thomas Moran, an American artist of New York"s Hudson River School who earned fame by painting scenes of the Western frontier. In 1871, Moran and photographer William Henry Jackson were invited on an expedition to the Yellowstone region to accompany a team from the US Geological Society while they conducted the first comprehensive survey of the area. Moran"s paintings and Jackson"s photographs from the trip immediately captured the public"s attention and inspired Congress to establish Yellowstone as the first national park in 1872.Desktop Version
Ingenuity in action on the Santa Monica Pier
Ingenuity in action on the Santa Monica Pier
The story of the Ferris wheel, first invented for the 1893 World’s Fair in Chicago, is a prime example of human ingenuity in urban environments, which happened to be the theme of our most recent photo contest. Congrats to contest winner Chris Fabregas, who captured this shot of human ingenuity in action on the Santa Monica Pier in California. Santa Monica debuted its Ferris wheel here in 1996 and then adapted it two years later to make it the world’s first solar-powered Ferris wheel, using clean energy for the ride that propelled about 800 passengers an hour. In 2014 it was replaced with a newer version that sports 174,000 LED lights, providing for glittering nighttime scenes just like this.Desktop Version

It’s Endangered Species Day
It’s Endangered Species Day
We chose this photo of a peregrine falcon—a female, walking across the rail of a balcony in Chicago—to inspire hope on Endangered Species Day. Not every animal listed as endangered is doomed to extinction. Peregrine populations were decimated by the use of pesticides, such as DDT, in the mid-20th century. The chemicals accumulated in the birds’ bodies, causing weak eggshells and high mortality rates for chicks. But by the 1980s humans had learned the cause, reduced and eliminated the various chemicals, and helped the birds rebound with gusto.Desktop Version
The tale of squirrels like Nutkin
The tale of squirrels like Nutkin
If this picture looks right out of Beatrix Potter"s world, we"d say you have a good eye for a story. In 1903, Potter published "The Tale of Squirrel Nutkin," about a cheeky squirrel who taunts an owl with silly riddles until he pushes things too far—narrowly escaping with his life, minus a tail. Potter based Nutkin on the red squirrel, the only native squirrel species in the UK. The red squirrel population saw a steep decline here after humans introduced the larger nonnative Eastern gray squirrel in the late 1800s. But today in the UK, the red squirrel is a protected species, bolstering efforts to keep the gray numbers in check and preserve habitat. Estimates put the red squirrel population in the UK at fewer than 140,000, with the vast majority living in the woods of Scotland, like our little friend here.Desktop Version
North Cascades National Park at 50
North Cascades National Park at 50
You’ve heard of Yosemite, Yellowstone, and Glacier National Parks–but here’s a lesser-known destination to add to your national park bucket list. North Cascades National Park celebrates its 50th anniversary today. Located about 100 miles northeast of Seattle, and stretching up to the Canadian border, it"s surrounded by two national recreation areas and other protected lands, including several national forests and wilderness areas, and by Canadian provincial parks in neighboring British Columbia. Despite all of this stunning wilderness, North Cascades National Park isn"t nearly as busy as the big-name parks, and that can be a good thing. Here you’ll find the most extensive system of glaciers in the lower 48 states—more than 300 glaciers. It’s the glaciers that lend a lovely turquoise hue to freshwater lakes, like Ouzel Lake on today’s homepage. The 500,000-acre park also boasts spectacular wildlife, alpine forests, and waterfalls. See you there?Desktop Version

Don’t look down
It"s Swiss National Day, and the citizens of Switzerland are taking the day off. They’re celebrating the 1291 confederation of regional cantons that led to the formation of their country. The nation first celebrated this milestone 600 years later, in 1891, but the day wasn’t declared an official holiday until 1994. Perhaps the Swiss are able to summon that level of patience as they cross the Charles Kuonen Suspension Bridge in the Alps near the village of Randa. At 1,621 feet, the bridge is currently ranked the world’s longest pedestrian suspension bridge. It’s also pretty high–at one point along the span, brave crossers are 279 feet above the ground. Just keep moving forward and maybe yodel a bit to distract yourself…Desktop Version

In the Most Serene Republic
In the Most Serene Republic
Though some of the details of the founding of San Marino vary depending on who is telling the story, what"s certain is that in the 4th century CE, a stone mason built a Christian chapel on a hill near the Mediterranean coast and founded the settlement that would share a name with Saint Marinus. Over the centuries European nations grew, shrank, and changed—but San Marino remained, ultimately bordered on all sides by Italy. Today, this tiny nation, sometimes called the Most Serene Republic of San Marino, celebrates 1,718 years of existence and its continued status as the world"s smallest republic—24 square miles of quaint European charm embedded in Italy"s northeastern region.Desktop Version

Fall color sweeps across the West
The leaves are changing across the West, and few views are more striking than this one of the fall foliage in the Uncompahgre National Forest in the shadow of Chimney Rock. The spire and its neighbor Courthouse Mountain dominate the landscape here year-round, but the changing colors make this area—and drives along the nearby Million Dollar Highway—even more scenic in the fall.Desktop Version
1, 1, 2, 3: It s Fibonacci Day!
1, 1, 2, 3: It s Fibonacci Day!
Today"s date, November 23, can be represented as 11/23, or 1, 1, 2, 3—the beginning of the Fibonacci sequence of numbers. Likewise, as the leaves on the Queen Victoria agave in today"s image spiral out from the center, they also express the Fibonacci sequence. This unique sequence of numbers was introduced to Europe in 1202 by the Italian mathematician Leonardo of Pisa (posthumously named Fibonacci) in his revolutionary work, the "Liber Abaci." The book begins by describing the Hindu-Arabic numeral system or "Modus Indorum’—0 1 2 3 4 5 6 7 8 9—and shows how its application could simplify trade and make calculations faster and easier (most of Europe at this time used Roman numerals).Desktop Version
Tiny fliers head south
Tiny fliers head south
The ruby-throated hummingbird in today"s homepage image is snacking on some yellow bells in the Texas Hill Country, preparing for its long journey south for the winter. This time of year, the hummingbirds leave the northern latitudes of the eastern US and Canada, migrating to the warmer climes of Mexico and Central America. Along their route, many will cross the Gulf of Mexico in a single 500-mile flight, which can take 18-22 hours of nonstop flying at speeds of up to 35 miles per hour. Tiny but fierce, the ruby-throated hummingbird weighs less than a nickel. It beats its wings about 53 times a second on average, but during courtship the wingbeat rate increases to 200 times per second, the fastest of any bird.Desktop Version

A bite of ancient history
Apples can be traced back to the mountains of Central Asia. In late 4th century BCE, Alexander the Great was busy conquering that region, and while in what is modern-day Kazakhstan he came across wild apples. Alexander’s military machine brought some of the plants back to Europe, and over the centuries, cuttings and seed splices began to produce the fruit as we know it now. The apples ready for harvest in this photo are on Salt Spring Island in British Columbia, Canada—a long way from Central Asia.Desktop Version

Basking in the glow
Norway may not be top of mind for most sun seekers, but around the middle of May until late July, head north to the part of the country inside the Arctic Circle and you can experience a natural phenomenon known as the midnight sun. During these few months the sun is visible at midnight local time, like you see in today"s image of Norway"s North Cape. Of course, as nature strives to maintain a balance, during winter this region experiences polar night, when the sun never rises above the horizon.Desktop Version

The ‘Night of Nights’
This is the cypress tunnel at Point Reyes National Seashore, a nature preserve on the California coast north of San Francisco. The tunnel leads to KPH, a ship-to-shore radio station that once broadcast messages to marine craft in the Pacific. KPH stopped operations in 1997, as more sophisticated radio equipment and satellite communications made radio stations like it obsolete. Now it’s one of the unusual features of Point Reyes, open to visitors interested in a glimpse of the past.Desktop Version
The moai you know
The moai you know
Roam around tiny, remote Easter Island and you"ll find almost 900 of the stern stone faces called moai. They seem ancient as the pyramids, even a little alien, but they were actually sculpted between 500 and 800 years ago from compacted volcanic ash that"s as terrestrial as it comes. You"re seeing six of the 15 moai that stand on Ahu Tongariki, the largest ahu (stone platform) on the island. These statues were toppled in the 18th or 19th century along with other moai island-wide for reasons not fully known to scholars, though earthquakes or possible tribal infighting are postulated. The statues were later buried by a tidal wave and lay in ruins until the 1990s, when they were excavated and placed back on the ahu.Desktop Version
Swimming into the season
Swimming into the season
This aquatic candy cane is called a banded pipefish. You won"t find it at the North Pole or on your Christmas tree, but in the tropical seas of the Indo-Pacific region, from Australia and Japan to the Philippines and South Africa. It"s in the same family as the seahorse, and like its cousin, the pipefish has plates of bony armor covering its body. This gives it protection, but a rigid body (like a candy cane!), so it swims by rapidly fanning its fins. Also like the seahorse, it"s the male pipefish—not the female—who carries the eggs. After an elaborate courtship dance, the female deposits her eggs in the male"s brood pouch, where they develop until the male gives birth. We"re not making this stuff up, but we can"t vouch for the theory that the red-and-white banded pipefish has a minty taste.Desktop Version
