Celebrate Mandela Day
Celebrate Mandela Day
Today we’re in Howick, a town near the east coast of South Africa, where this monument honors the anti-apartheid activist and South African president Nelson Mandela, who would have turned 100 today. Like Martin Luther King Jr. Day in the US, Mandela Day—celebrated on Mandela’s birthday—is intended not as a holiday exactly but as a day to answer the ‘global call to action’ by finding ways to engage in service to your local community. The best part about Mandela Day? You don’t need to be from South Africa to observe the event.Desktop Version
Cenote near Puerto Aventuras, Mexico
Cenote near Puerto Aventuras, Mexico
Like a giant block of Swiss cheese, Mexico"s Yucatán Peninsula is riddled with holes called cenotes. Cenotes form when subterranean limestone dissolves, allowing underground water to penetrate. The rock above may cave in, forming a sinkhole that reveals the cool, often crystal-clear water. Other cenotes may remain below the surface, hidden and often unexplored. Cenotes vary in size from very small to several dozen yards across, and recent discoveries have shown that some cenotes lead to a series of underground cave systems that can span several miles in length.Desktop Version
The Spirit of Harlem by Louis Delsarte
The Spirit of Harlem by Louis Delsarte
On International Jazz Day, we"re looking at "The Spirit of Harlem," a glass mosaic mural by artist Louis Delsarte. Located near the legendary Apollo Theater in New York City"s Harlem neighborhood, it depicts, among others, jazz greats Cab Calloway and Count Basie. Originally commissioned in 2005, the mural was covered up in 2017 when a new store moved into its location. After a petition and protests, the retailer worked with Delsarte to restore the mural and add a new plaque dedicating it to the Harlem community. Delsarte, whose other works include a 125-foot-long mural at the Martin Luther King Jr. Natatorium in Atlanta, died in May 2020.Desktop Version
Yosemite National Park, California
Yosemite National Park, California
Fancy witnessing a fiery waterfall? The seemingly impossible can be found at this time of year on the eastern side of El Capitan, Yosemite National Park"s famous rock face. Horsetail Fall is a seasonal waterfall that flows only when there has been plenty of snowfall, and when temperatures have been warm enough to melt it. For a couple of weeks in February, if skies are clear, water is flowing, and the sun shines at just the right angle, the long, slender waterfall takes on a glowing, flame-hued appearance. Hundreds gather in Yosemite Valley to see this mesmerizing natural spectacle. The phenomenon has earned the moniker "firefall," an homage to the historic Yosemite Firefall, a manmade event from the top of the park"s Glacier Point that took place between 1872 to 1968. Eventually, park rangers decided that dumping embers over a cliff onto the land below wasn"t the brightest idea.Desktop Version
International Day for Monuments and Sites
International Day for Monuments and Sites
Located high in the Andes Mountains, Peru"s Machu Picchu is believed to have been an estate for the Inca emperor Pachacuti, who ruled in the mid-15th century. This "Lost City of the Incas" is one of the world"s most famous archaeological sites, an engineering marvel, built without mortar, metal tools, or the wheel. As an icon of Inca civilization, it is a perfect fit for UNESCO"s International Day for Monuments and Sites, which has been celebrating important cultural heritage sites for 40 years. Landmarks such as the Pueblo Indian dwellings of Mesa Verde, the Taj Mahal, the Great Pyramid of Giza, and the Parthenon give us the opportunity to look back at the cultures that came before us and preserve their memory for future generations.Desktop Version
National Hammock Day
National Hammock Day
It’s National Hammock Day! A day to slowly unwind while rocking gently from side to side. These days, hammocks are associated with summer relaxation, but they were originally developed by Central Americans to protect them from dangerous insects and animals. Today the hammock is a traveler"s best buddy, made from a variety of materials like fabric, netting, or rope. But where best to hang it? Florida boasts some beautiful hammock hang-out spots, like the bald cypress tree pictured on our homepage. Have hammock, will travel and relax. It"s just that simple.Desktop Version
Val Gardena, South Tyrol, Dolomites, Italy
Val Gardena, South Tyrol, Dolomites, Italy
Val Gardena in Northern Italy is a popular destination for skiing, rock climbing, and woodcarving enthusiasts, which transforms into Christmas Valley at this time of year. Wooden huts open their doors to visitors, and a nostalgic cable car ride, each cabin adorned with twinkling fairy lights, travels above snow-covered slopes. During the 18th century, the valley became famous for its production of intricately carved wooden figurines, initially made to decorate Catholic churches. Among those creations, the peg wooden doll emerged as one of Val Gardena"s best-known products and is still being produced today.Desktop Version
Indigenous living
Indigenous living
Just north of Ketchikan, Alaska, is Totem Bight State Historical Park, a 33-acre space dedicated to preserving elements of the Indigenous Haida and Tlingit cultures of this area. Visitors can walk through the low door of the Clan House to see how families from the tribes once lived. The park also boasts a collection of 14 traditionally crafted totem poles based on 19th-century originals. The order and positions of the symbolic faces on the poles show the progression of a specific story that can be interpreted by those who know how to "read" the carvings.Desktop Version

Plitvice Lakes National Park in Croatia
Plitvice Lakes National Park in Croatia
In a country more famous for its coastline, about a million visitors each year venture inland to amble along these boardwalks and marvel at spectacular lakes and mountains. Plitvice Lakes National Park is the oldest and largest of Croatia"s national parks. The big attraction is the series of 16 descending, turquoise-colored lakes, connected by subterranean karst rivers, and above ground by streams and waterfalls. The lakes are separated by natural dams of travertine, which is created by the interplay of water, plant material, and bacteria. The water changes color from green to azure to gray depending on the angle of the light and the density of minerals and organisms in the water. About 11 miles of wooden boardwalk make it easy for people to wander among the lakes, falls, and caves that are open to visitors year-round.Desktop Version
The lemurs of Madagascar
The lemurs of Madagascar
What better place to ring in World Lemur Day than Madagascar? The island, about the size of Texas off the coast of southeastern Africa, is the native home to lemurs. Today you"ll find over 100 species and subspecies of the critters here. Most are small, with a pointed nose, large eyes, and a tail. They mainly live in trees and can be highly social, like the ring-tailed lemurs on our homepage, or live a solo existence like the elusive aye-aye. Lemurs have opposable thumbs and five fingers with fingernails on each hand, characteristics that help secure their spot as members of the primate order of mammals. About 65 million years ago, scientists believe, lemurs drifted on rafts of vegetation from the African continent to the shores of Madagascar. Safe from competition and most predators, lemurs evolved into many highly specialized varieties and now can be found in almost all habitats on the island.Desktop Version
Notes from an underground lake
Notes from an underground lake
The Ruskeala Mountain Park is an eerily beautiful reminder of the booming mining industry that thrived for centuries in this area of Russia near the border with Finland. Located on the site of an abandoned marble quarry, the park opened to the public in 2005. The centuries-old quarry has been flooded with groundwater since the end of World War II, although some old buildings and kilns from the mines are still intact.Desktop Version

Tambopata National Reserve, Peru
Those brave enough to step out over this suspension bridge will be treated to a macaw"s-eye view of the Amazon rainforest, on which the survival of life on Earth depends. The vast Amazon biome, which spans 2.6 million square miles—an area twice the size of India—stores enormous amounts of carbon and supports approximately 10% of all known animal and plant species on Earth.Desktop Version
Bridge of Hillsborough County
Bridge of Hillsborough County
The Hancock-Greenfield Bridge (aka County Bridge) has offered a picturesque passage over the Contoocook River in southern New Hampshire since 1937. It was built to replace another covered bridge that had been destroyed in a flood. But why even build a covered bridge? In a word, longevity. The roof and walls help protect the timber supports from rot. For comparison, an uncovered wooden bridge lasts an average of 20 years, while the covered variety can reach 100 years or more.Desktop Version
San Francisco’s City Hall illuminated by the iconic colors of Pride
San Francisco’s City Hall illuminated by the iconic colors of Pride
We’re celebrating Pride weekend with a view onto a Beaux-Arts gem that has a prominent place in the history of gay rights and culture. Even the city of San Francisco itself has played an outsized role in fostering gay pride, community, and visibility. It’s a legacy that can be traced along the timeline of the city’s many firsts. The San Francisco Bay Area held one of the first Pride parades after the 1969 Stonewall riots in New York, the event that sparked the gay liberation movement and the modern fight for LGBTQI+ civil rights. This is just part of the heritage that will be celebrated at San Francisco’s Pride this weekend, where people will be marking the 50th anniversary of the Stonewall riots. A big parade is planned with vibrant displays that will decorate Market Street, continuing all the way to the Golden Gate City’s Civic Center.Desktop Version
Martin Luther King Day
Martin Luther King Day
Sculptor William "Bill" Tarr created the large, untitled memorial that welcomes students to Martin Luther King Jr. Educational Campus in Manhattan. The steel block features quotations from King and famous phrases from the civil rights movement. It was designed to weather over time, changing in color and texture as it ages. The school was founded in 1975 and is now home to seven distinct high schools, each focusing on a different discipline, including law, technology, and the arts.Desktop Version
Pont Rouge
Pont Rouge
When the Pont Rouge (Red Bridge) of Sainte-Agathe-de-Lotbinière was built over the Palmer River in 1928, covered bridges were already commonplace here in Quebec. Simple designs imported from the United States allowed relatively untrained workers to quickly construct crossings like this. "Ponts rouges" (often called this whether or not they were painted red) popped up wherever rural French Canadians required a convenient river crossing—as many as 1,500 were built between the late 1800s and the 1950s. Today fewer than 100 still stand, and some—like this one—are protected by local and provincial agencies for historic preservation.Desktop Version
The lights of Paris
The lights of Paris
As twilight turns to night, the city of Paris lights up. Streets and buildings are bathed in light, alongside grand monuments such as the Hôtel National des Invalides, whose famous dome shines out in our homepage image. It was built during the 17th century under Louis XIV, as a hospital and home for army veterans. It was also Louis XIV, known as the Sun King, who ordered streetlights to be erected throughout the city to light up dark alleys where lawbreakers might lurk. Parisians were also asked to put up lanterns and oil lamps, and place lit candles in their windows.Desktop Version
Groundhog Day
Groundhog Day
Groundhog Day is a North American tradition with roots in the February 2 Candlemas observance practiced by German immigrants. The most well-known Groundhog Day celebration, in Punxsutawney, Pennsylvania, was first promoted by a local newspaper editor in 1886. Thousands of people gather in Punxsutawney each year to witness the groundhog emerge from its burrow, and more importantly, to see if the critter spots its shadow. If it does, winter will go on for six weeks, according to tradition. If it does not, spring-like conditions are said to be coming. Studies have yet to prove any link between the two events, but that hasn’t cast a shadow over this unusual tradition, which remains as popular as ever in the 21st century.Desktop Version
Dark Sky Week
Dark Sky Week
During International Dark Sky Week, we"re counting ourselves lucky to have this spectacular nighttime view, considering the astonishing fact that 83% of the global population lives under a light-polluted sky. Unneeded artificial light is classified as a pollutant and has been proven to have harmful side effects. Not only does it waste money and energy, it also disrupts plants and animals, is believed to impact the climate, and blocks our view of the universe.Desktop Version
Paleontology meets art
Paleontology meets art
Though it looks like a fresco from ancient Greece, this is the fossilized remains of a fern found in Córdoba, Spain. The fossil dates back to the Carboniferous period, roughly 350 million years ago. This is a "compression fossil"—where a small amount of the original plant material was retained with the mineral deposits that helped form the impression. Why all the paleobotany talk? It"s National Fossil Day, and we’re excited! Whether you make a trip to your local natural history museum, trek off to a national park with a fossil exhibit, or just look at fossil photos on the web, we hope you find a fun way to celebrate National Fossil Day.Desktop Version

Let’s have a ball
Let’s have a ball
You know a game must be fun if it’s stuck around for eight centuries–and that’s how long folks have been playing lawn bowling (in some form or another). It was the invention of the lawn mower in 1830, allowing for smoothly cut bowling greens, that really popularized the sport. Our homepage features the balls called ‘woods,’ or ‘bowls,’ that competitors use during game play. The objective is to roll the grapefruit-sized balls toward a smaller ball called a ‘jack,’ and points are awarded to the players who come the closest. Fancy a game?Desktop Version
World Meteorological Day
World Meteorological Day
They might look like spaceships from a retro sci-fi movie, but these strange shapes hovering above the mountains in Patagonia are of earthly origin. These are lenticular clouds, named after their lens-like shape. They form near hills and mountains where moist air is pushed up and over the peaks, cooling as it rises and condensing into water droplets. As wind blows over the mountains it can create a series of waves in the air, and these unusual clouds form in the crest of those waves.Desktop Version
