Delicate Arch, Arches National Park, Utah
Delicate Arch, Arches National Park, Utah
This place wasn"t built overnight—nature took its time to craft this masterpiece. What you see at Arches National Park, Utah, is the result of over 300 million years of erosion, uplift, and weathering. These arches were formed when salt beds were left behind by ancient seas. Over time, layers of sandstone cracked, shifted, and slowly wore away, revealing more than 2,000 natural arches. These formations are made mostly of Entrada and Navajo sandstone. The park was recognized as a national monument in 1929 and was later upgraded to national park status in 1971.Desktop Version

Yellowstone for the National Park Services birthday
Yellowstone for the National Park Services birthday
Today, the National Park Service celebrates another trip around the sun—and nearly 85 million acres of American beauty under its care. From geysers that spout like soda cans to ancient cliff dwellings tucked into canyon walls, the NPS has spent over a century preserving, protecting, and inviting people to take a hike—literally. In 1916, President Woodrow Wilson signed the Organic Act into law, officially creating the NPS to "conserve the scenery and the natural and historic objects." Since then, the NPS has grown to oversee more than 400 sites, including national parks, battlefields, monuments, and seashores.Desktop Version
Splendid leaf frog
Splendid leaf frog
Don"t let the name fool you—this frog isn"t just leafing around. The splendid leaf frog (aka splendid tree frog) is a rainforest resident with a flair for the dramatic: neon legs, sticky feet, and a disappearing act. One minute it"s a humble green leaf, the next it"s a flash of color mid-leap, startling predators. This frog lives high in the canopies of Central and South America, especially in Costa Rica, Panama, and parts of Ecuador and Colombia. It spends its days snoozing on leaves and its nights foraging for insects. With vertical pupils and a golden glow, oversized eyes help this frog spot prey in the dark. Thanks to sticky toe pads and strong limbs, it can cling to branches and leaves like a pro, even in the canopy"s slippery heights.Desktop Version

Mesquite Flat Sand Dunes in Death Valley National Park, California
The Mesquite Flat Sand Dunes, located near Stovepipe Wells Village in Death Valley National Park, are the most accessible and iconic dunes in the park. They are formed by a combination of eroding mountains to the north that supply sand, prevailing winds that move it, and surrounding mountains that trap it from the south—creating a stunning landscape of rippling sand hills. Named after the resilient mesquite trees that grow here, the dunes offer breathtaking views at sunrise and sunset, as well as exceptional stargazing opportunities.Desktop Version
Patriot Day
Patriot Day
September 11, 2001, began like any other day—until history changed in an instant. Nearly 3,000 innocent lives were lost in the terrorist attacks on the World Trade Center, the Pentagon, and aboard United Airlines Flight 93. Today, on Patriot Day, we honor the fallen and the countless acts of courage that emerged in the face of tragedy, from firefighters and first responders to ordinary citizens who became heroes. At 8:46 AM Eastern Time—the moment the first plane struck the North Tower—Americans observe a moment of silence. Permanent memorials now stand at each of the three sites. Visiting one or volunteering in your community is a meaningful way to participate in the National Day of Service and honor those who continue to serve.Desktop Version

Pictured here is a spectacular view of a delta in the Venetian Lagoon, Italy. Spanning over 212 square miles, this lagoon is a rich mosaic of islands, mudflats, canals, and marshes, and it"s one of the largest wetlands in the entire Mediterranean Basin. The lagoon isn"t just a scenic wonder—it"s a place steeped in history and innovation. Formed after the last Ice Age, it became a refuge for people fleeing invasions around the time of the fall of the Western Roman Empire in 476. In the centuries that followed, those early settlers began building what would eventually become the iconic city of Venice.Desktop Version

Vatican City with St. Peters Basilica
Vatican City with St. Peters Basilica
In the middle of Rome, Italy, lies an entire country of its own: Vatican City. At just 121 acres, it"s the smallest independent nation in the world, yet its reach spans centuries and continents. Home to the pope and the spiritual center of the Roman Catholic Church, this walled enclave is a blend of art, history, and devotion. At its core stands St. Peter"s Basilica. Seen in the distance in today"s image, this Renaissance masterpiece is built over what is believed to be the tomb of St. Peter, the first bishop of Rome. With its soaring dome dominating the skyline, the basilica is one of the largest churches in the world. Just beyond the basilica lies St. Peter"s Square, where thousands gather for papal blessings. The Vatican Museums and the Sistine Chapel, which houses Michelangelo"s famed ceiling, are other must-sees. Despite its size, Vatican City has its own postal service, telephone system, and banking system.Desktop Version

World Population Day
World Population Day
We are living in a full house, and it is getting fuller. With 8.2 billion people and counting, World Population Day highlights how that growth affects cities, food, and the future. First observed in 1989, the day focuses on how unchecked population growth affects sustainability. The event was inspired by Five Billion Day in 1987, which marked the approximate date when the global population hit that milestone. As cities expand, green spaces shrink, and agriculture competes for limited land and water resources. But there is a way forward—investing in education, improving access to healthcare, and building smarter cities can balance growth with sustainability.Desktop Version
Maritime forest in Cumberland Island National Seashore, Georgia
Maritime forest in Cumberland Island National Seashore, Georgia
Before you hit the beach, you"ll hear it—the rustle of leaves in salty air, the creak of twisted trunks, the hush of an old world. Welcome to the maritime forest of Cumberland Island National Seashore on the southernmost stretch of Georgia"s Atlantic coast. Salt spray, sandy soil, hurricanes? The trees here stand their ground. Live oaks bend but don"t break. Saw palmettos crowd the ground like leafy bodyguards, while Spanish moss hangs from branches like nature"s fringe. This maritime forest is one of the best remaining examples of this rare habitat in the United States. Thanks to its national seashore status, the island has been spared from the concrete creep seen on other coastlines.Desktop Version

"Life under the sea is better than anything they got up there," Sebastian the crab once told Ariel. But are we doing enough to protect that underwater world? On June 1, we celebrate World Reef Awareness Day, a time to recognize the beauty—and fragility—of coral reef ecosystems. One magnificent example is the New Caledonian barrier reef, which wraps around Grande Terre, New Caledonia"s largest island. At over 930 miles long, it"s one of the longest continuous barrier reefs in the world. Its vast 9,300-square-mile lagoon is home to over 2,300 fish species, endangered dugongs, green sea turtles, and migrating humpback whales.Desktop Version

Kalalau Beach on the Nā Pali Coast, Kauai, Hawaii
No road signs, no souvenir stands—just 11 miles of mud, cliffs, and sweeping views leading to one of Hawaii"s most remote beaches.

World Turtle Day
World Turtle Day
No need to hurry, because today marks the 25th anniversary of World Turtle Day. Turtles and tortoises thrive in a variety of environments and are linked to wisdom and perseverance. All tortoises are turtles, but not all turtles are tortoises. While turtles are smaller and built for swimming, tortoises are larger, heavier, and adapted for life on land. The American Tortoise Rescue (ATR) established World Turtle Day to raise awareness and protection efforts on May 23 each year. ATR has helped rehabilitate, rescue, and rehome around 4,000 turtles and tortoises, working to protect them and their disappearing habitats.Desktop Version
Big Bend National Park in Texas turns 81
Big Bend National Park in Texas turns 81
They say everything"s bigger in Texas—and Big Bend National Park has been living up to the slogan since forever. Efforts to preserve this 801,163-acre area of West Texas began in the 1930s and culminated in its official designation as a park on June 12, 1944. Big Bend remains one of the most remote and least-visited national parks in the country. It"s not just one landscape, it"s three: the Chihuahuan Desert, the Chisos Mountains (pictured here), and the Rio Grande. Big Bend sits on the US–Mexico border, and its history reflects that blend. Indigenous peoples, Spanish explorers, ranchers, miners, and modern travelers have all left their footprints. Petroglyphs, ruins, and old trails show the land"s story began long before it became a park.Desktop Version
