Horsetail Fall, Yosemite National Park, California
Horsetail Fall, Yosemite National Park, California
Illuminated by the setting sun on Yosemite"s famous El Capitan is a rare natural phenomenon known as the "Firefall," which appears for just a few weeks a year. From mid to late February, the sun is at just the right angle to set Horsetail Fall aglow, but only if sufficient water is flowing and the sky is clear. Even then, the Firefall only lasts for about 10 minutes in the evening, so vantage points can be very crowded.Desktop Version
China s colorful terraced pools
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

Float on
We’d like to trade our usual Monday morning experience in for this one, please. Welcome to the Albuquerque International Balloon Fiesta in New Mexico. The festival continues through October 14, with plenty of on-the-ground entertainment beyond those balloon rides that might take you east of the city, to the foothills of the Sandia Mountains, seen in this photo. Many hot air balloon rides offer a champagne toast as part of the experience. The champagne tradition may have sprung from early balloon pilots having to land in farm fields on private property. Aeronauts began carrying champagne or other drinks with them to offer to the confused and sometimes angry landowners. You’re welcome to land in our backyard anytime, balloonists!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
A species worth defending
A species worth defending
Some folks are quick to dismiss bats as simply ‘scary’ (and the association with Halloween doesn’t help things). But during Bat Appreciation Month, consider their valuable contributions to the ecosystem. Bats around the world help to control bug populations (including agricultural pests), pollinate important plants, and disperse seeds–helping to regenerate lands that have been overharvested or otherwise damaged. In fact, what’s truly scary is how much we’d miss bats if they were gone. In North America, a disease called white-nose syndrome has killed millions of bats since it was identified in 2006–and scientists are working hard to find a way to help bats recover. One easy way to help bats is to build or buy a bat box for your property, and provide them with a safe space to roost.Desktop Version
There’s treasure in them thar hills
There’s treasure in them thar hills
This wintry view comes from Oregon’s Painted Hills, part of the John Day Fossil Beds National Monument and home to one of the most complete fossil records on the planet. Paleontologists have uncovered fossils here that date as far back as 44 million years ago, when this region had a hot, wet, subtropical climate, home to crocodiles and rhino-like plant eaters. And what’s above ground here is equally impressive. This is only a glimpse of the portion of the monument called the Painted Hills, named for its vivid colors that are a result of layers of sediment from various geologic periods.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

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

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
A crested partridge
A crested partridge
Our moodily lit crested partridge is a female. Though her plumage includes vibrant green and copper, the male sports the red crest that gives the bird its most common name. Unless you travel to the biogeographic region of Southeast Asia known as Sundaland, you may have to head to your local zoo to get a glimpse of this bird. But don’t look for it up in the trees--the crested partridge prefers to walk, not fly.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
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
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
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
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

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

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
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

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

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
