In the path of the pronghorn
In the path of the pronghorn
As the days lengthen and spring flowers bloom, herds of pronghorns in Wyoming migrate north from their winter grounds in the Upper Green River Basin to Grand Teton National Park. The journey, which biologists have dubbed the "Path of the Pronghorn," covers about 150 miles across government and private lands. Pronghorns have walked this route since prehistoric times, though today, fences, highways, and other unnatural barriers have made the journey more perilous. To mitigate these dangers, wildlife corridors are being constructed over highways and under bridges, offering safer passage for these quintessential symbols of the American West. Conservation efforts like these have helped to make the "Path of the Pronghorn" one of the longest migration corridors remaining for large mammals in North America.Desktop Version
Singing praises of the oceans
Singing praises of the oceans
In Japan, mid-July brings an excuse to head to the beach. That"s because this time of year marks Marine Day (aka Ocean Day), an observance recognizing the close bond the island nation shares with the seas and ocean that surround it. Because Marine Day roughly coincides with the end of the rainy season, it has, over the years, become a sort of unofficial kickoff to the hot summer season. One place sure to attract visitors is the picturesque Minokake-Iwa rock formation seen here, lying off the island of Honshu and its mountainous 31-mile-long Izu Peninsula.Desktop Version
Bringing together history and technology
Bringing together history and technology
On the second Saturday in May, the Dutch celebrate an iconic national structure—the windmill—like these historic ones at Zaanse Schans. With hundreds of windmills across the country, many sites use the day to demonstrate how windmills work and host art exhibits. But the concept of using wind power isn’t just a historical anecdote—this renewable energy is experiencing a boom, and by 2050 is predicted to provide one-third of the world"s electricity.Desktop Version

The Children’s Cultural Festival in Reykjavik begins today
Audiences at the Harpa Concert Hall are usually a bit older, but today when the 2018 Children’s Culture Festival launches, there will be another crowd like this one: Children who will not just see performances, but also learn to develop some of those artistic and creative-thinking skills through hands-on workshops and interactive performances. The festival’s been held since 2010, with events in multiple locations around the city.Desktop Version

Wandering Watkins Glen
When we talk about celebrating public lands, the images that pop into our heads are generally icons of the famous national parks out West. Old Faithful, El Capitan, the Arches. Our photo for National Public Lands Day highlights the relatively unsung beauty of the more than 10,000 state parks dotting the nation from coast to coast.Desktop Version
Happy Arbor Day!
Happy Arbor Day!
A Chinese proverb advises, ‘The best time to plant a tree is 20 years ago. The second-best time is now.’ That’s especially true today. It’s National Arbor Day in the US and we’re featuring this dramatic photo of coast redwoods to remind you of the incredible power and importance of trees. The very first recorded Arbor Day took place in 1594 in the little village of Mondoñedo in Spain, organized by its mayor. The first US Arbor Day was observed in Nebraska City, Nebraska, on April 10, 1872. It was organized by journalist and politician Julius Sterling Morton, who’d moved to Nebraska from Michigan, and called his adopted state a ‘treeless prairie.’ He rallied celebrants at that first US Arbor Day to plant an estimated 1 million trees.Desktop Version
Happy Presidents Day
Happy Presidents Day
It"s hard to imagine a more appropriate place to celebrate Presidents Day than here, at the Mount Rushmore National Memorial. The monument features four of our most famous presidents—George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln. Four hundred workers using dynamite, hammers, and chisels crafted these 60-foot-high sculptures out of the granite mountainside in the Black Hills of South Dakota. Work on the monument began in 1927 and was completed in 1941.Desktop Version
A seabird gets schooled
A seabird gets schooled
This deep-diving Brandt"s cormorant appears to be on the hunt for a meal, and there"s plenty of Pacific chub mackerel to choose from here off the coast of Los Angeles, California. While seabirds like the cormorant are a threat to these fish, the mackerel aren"t exactly defenseless. Fish have many unique means of defense, such as traveling in dense schools like this one. It"s a technique that not only allows for speedy travel (because it reduces friction on most of the fish in the school)—schooling also makes it more difficult for predators to pick out an individual victim. For these fish, there"s safety in numbers. But when all else fails, they can take some advice from Dory in "Finding Nemo"—"Just keep swimming, just keep swimming."Desktop Version
A cliffside harbor in Sardinia
A cliffside harbor in Sardinia
The mining industry in Sardinia, Italy, was booming in the early 20th century, as European nations looked to reconstruct from the damage of World War I. But Sardinians faced myriad logistical issues trying to export the zinc, lead, and other minerals that were in high demand. Miners on the island were using modern techniques to extract more and more ore, but it wasn"t until 1924, when engineer Cesare Vecelli designed and built the mining infrastructure along the cliffs in Porto Flavia, that getting ore off the island matched their ability to extract it.Desktop Version
Of balloons and lost pantaloons
Of balloons and lost pantaloons
We all fly by the seat of our pants now and then, but how about flying with no pants at all? That was the plight of Jean-Pierre Blanchard and John Jeffries, who on January 7, 1785, made history over these chalk cliffs with the first aerial crossing of the English Channel. When their hydrogen-filled balloon dropped altitude due to overloading, the two tossed all the cargo they could into the drink below, britches included. Reaching France in their underpants, the undoubtedly chilly pilots still received a warm welcome.Desktop Version
Seven Magic Mountains art installation, Jean Dry Lake, Nevada
Seven Magic Mountains art installation, Jean Dry Lake, Nevada
It’s easy to see how this brightly colored art installation near Jean Dry Lake caught the eye of photographer Renz Alfonso Dela Pena, the winner of the Bing #Amplifyingenuity photo contest. The installation, created by artist Ugo Rondinone, includes seven towers of boulders that reach up to 30 feet high. Its bold colors are meant to contrast with the stark landscape here in the Mojave Desert, where the piece will remain on display at least through 2018.Desktop Version
Exploring the Pearl of the Atlantic
Exploring the Pearl of the Atlantic
We"re taking in a view of the island of Madeira, by far the largest island in the Madeira archipelago, which sits 320 miles off the coast of Morocco in the North Atlantic. Known as the "Pearl of the Atlantic," Madeira is part of an autonomous region of Portugal. It boasts a diverse forest ecosystem, endemic flora and fauna, and the largest living stand of laurel trees in the world. It"s a great place to hike, too. Trails run alongside irrigation channels, called levadas, that move water all over the island. Walks range from easy strolls in the countryside to precarious hikes along mountain ridges or into remote parts of the forests. Afterward, the calorie-depleted can dig into a local delicacy like peixe espada com banana (fried local fish with banana) and sip on Madeira wine. Saúde!Desktop Version

We"re standing on the Mall of New York City"s Central Park, in the middle of fall foliage season. When Frederick Law Olmsted and Calvert Vaux designed this quarter-mile walkway, they were inspired by Europe"s public spaces. They envisioned a "grand promenade" where people of all backgrounds, from the city"s monied elite to those of lesser status, could come together and mingle.Desktop Version

Our National Park Week virtual tour comes to a close at sunset on Ruby Beach, one of the many stunning corners of Olympic National Park in Washington state. A few miles from the shore is Destruction Island, where birds such as rhinoceros auklets may stop and rest after a day of gobbling up krill and squid in the cold Pacific waters. While the park includes miles of colorful Pacific coastline, it"s also famous for the Hoh Rainforest, an inland temperate forest notable for its towering old-growth hemlock and spruce trees.Desktop Version
Caribou on the move
Caribou on the move
Each fall a quarter-million caribou come together to form the Western Arctic Caribou Herd, a group that makes an epic migration through northwest Alaska. The caribou move south from their calving grounds in the Utukok River Uplands to their winter range on the Seward Peninsula. Fall is also the time when scientists attach radio collars to members of the herd, to track their location and health, and to gain information that will help conserve the species. When spring arrives, the caribou will complete the trip again in reverse, covering a total of 2,000 miles each year, give or take.Desktop Version

Welcome to Acadia National Park on Maine"s rocky, scenic coast. The 49,075-acre park covers about half of Mount Desert Island, smaller nearby islands, and a section on the mainland. The oldest national park east of the Mississippi River and the only one in Maine, Acadia packs a lot of geographical variety into its relatively small size. You"ll find miles of craggy coastline like the shore in our homepage image, woodlands, wetlands, and mountains. The park"s Cadillac Mountain is the highest point along the North Atlantic seaboard and a great spot to take in the sunrise.Desktop Version

For World Wildlife Conservation Day, we"re dropping in to visit a herd of African elephants at Addo Elephant National Park in South Africa. Established in 1931 to protect a small herd of just 11 African elephants, today Addo ranks as third largest of the 19 national parks in South Africa. It provides a safe haven for about 600 of these magnificent creatures, as well as Cape buffaloes, various antelope species, lions, hyenas, and endangered black rhinos.Desktop Version

A misty morning in Brazil
The Amazon rainforest is big. Almost unimaginably big. To begin to grasp its immensity, consider these numbers: The Amazon rainforest covers about 2% of the world"s surface area, nearly 2.1 million square miles across South America, mostly (nearly 60%) in the country you see here, Brazil. It"s an area that accounts for over half the Earth"s remaining rainforests. The breadth of biodiversity is incomparable—nearly 16,000 different tree species, 40,000 species of other plants, 2.5 million insect species, and over 2,000 different types of birds and mammals. Incredibly, perhaps a tenth of the planet"s known species call the Amazon home, many of which have not even been identified.Desktop Version

To mark International Day of Peace, we invite you to look closely at the colorful sail in today"s homepage photo. It"s a composite of 120 small panels painted by children from different ethnic and social backgrounds—each panel offers a message of hope for a better world. The Ship of Tolerance is part of an international outreach program created by the Kabakov Foundation that aims "to promote art as a medium for communication and cooperation between diverse cultures while nurturing the growth and development of young artists in all disciplines." Children are taught the importance of understanding others and making friends with those outside their own cultural experiences. You"re looking at an installation that was moored in Lake Zug, Switzerland.Desktop Version
Hello, harbinger of spring
Hello, harbinger of spring
Welcome back, little mountain bluebird. Although this bright fellow may be enduring the last of this year"s snow in Yellowstone National Park, his presence means winter will soon be ending. The bluebird is a symbol of happiness and a welcome sign of spring in many cultures. Soon other migratory birds will arrive in the Greater Yellowstone Ecosystem—an 18-million-acre tract that includes Grand Teton National Park and surrounding national forests. It"s the world"s largest intact ecosystem in the northern temperate zone. What exactly does that mean? Since wolves were reintroduced to Yellowstone 25 years ago, all the animal species that were first documented by European explorers can still be found here.Desktop Version

The Unfinished Obelisk near Aswan, Egypt
This massive carving was to be larger than most other obelisks of Egypt 3,500 years ago. But because the nearly 140-foot creation developed a significant fissure in the stone, it was abandoned, inspiring the current name: The Unfinished Obelisk. The stone quarries here in Aswan, a city in southern Egypt, offer a glimpse of the industry that once fueled the region’s economy.Desktop Version

At the foot of Dubrovnik s Gibraltar
The stairs in today"s photo lead to Fort Lovrijenac, an 11th-century fortress jutting out into the Adriatic Sea just outside the western wall of Dubrovnik, Croatia. "Game of Thrones" fans will recognize these doors as entrances to a dwelling in the fictional city of King"s Landing. Legend claims that when the fort was built on this rocky coastal outpost, it took just three months to construct. The locals of what was then Ragusa knew they had limited time before their rivals, the Venetians, would arrive to build their own outpost and rule over them. According to "The Chronicles of Ragusa," the plan worked—the fort was completed just as the surprised Venetians arrived in ships heavy with supplies.Desktop Version

Our photo today has been digitally altered by NASA’s Earth Observatory team to remove natural light. Doing so reveals just how much artificial light human settlements generate. We share this image to draw attention to the observance of World Population Day today. The event was inspired by the Day of Five Billion on July 11, 1987, when the United Nations estimates our global population reached that milestone. Each year, World Population Day encourages us to think about how our growing numbers might affect our future, and the future of the planet we live on.Desktop Version
Marine Day in Japan
Marine Day in Japan
In Japan, the third Monday in July is Marine Day (also known as Ocean Day), a day to show appreciation for the seas and oceans. Other nationalities have similar observances, but as inhabitants of an island nation, people in Japan can claim a particularly strong connection to the waters that surround them. The modern holiday also serves as an official start of summer in Japan, and many folks hit the beach to celebrate the end of tsuyu, the rainy season. The holiday started as Marine Memorial Day in 1941 to mark the anniversary of the return of the Meji Emperor from a voyage in 1876, but it wasn"t observed as a national holiday until 1996. Some also mark Marine Day with environmentally friendly activities. In Okinawa, people throw EM (effective microorganism) mudballs into the sea—these contain bacteria and yeast targeted at eliminating sludge and slime. Other areas host beach cleanups and aquariums host special Marine Day events.Desktop Version
