Shadows on the solstice
Shadows on the solstice
Roughly 5,000 years ago, ancient inhabitants of the British Isles somehow dragged as many as 40 giant stones—the heaviest weighing an estimated 16 tons—onto this grassy plateau in what is now England"s Lake District National Park in Cumbria. They then grouped them into the stone circle at Castlerigg, seen here casting shadows from the low winter sun. Archeologists believe stone circles were arranged to align with solar and lunar positions. They were used in elaborate rituals to celebrate occasions like today"s winter solstice, the shortest day (and longest night) of the year in the Northern Hemisphere.Desktop Version
Dressed for winter fun
Dressed for winter fun
Native to North America, mountain goats spend much of the year scaling peaks from south-central Alaska down to the northern Rockies. They tend to live at high altitudes, often above 13,000 feet, where their sure-footed climbing ability allows them to clamber up extraordinarily steep, rocky slopes. In the winter, they"ll migrate down to slightly lower elevations to seek shelter in subalpine forests with south-facing rocky ledges, where the sun and relentless winds keep ice to a minimum. Here, they forage for lichen, mosses, grasses, and other greens. Their woolly, two-layered coats keep them toasty as temperatures dip, which is probably why even in the chill of western Montana this young mountain goat—or kid—appears to be having a ball. Enjoying winter is all about how you dress.Desktop Version
Four Sisters, thousands of trees
Four Sisters, thousands of trees
You"ll find this wintry, sylvan scene on the slopes of Mount Siguniang, the tallest summit of the Qionglai Mountains in southwest China. Its name, which translates as "Four Sisters Mountain," is inspired by the local Tibetan legend behind its four distinct peaks. According to the story, four sisters saved their people using a magic mirror to turn themselves into the mountain to imprison the devil. The tallest peak, named "Peak of the Youngest Sister," stands at 20,500 feet and is an extremely challenging climb—it"s rarely attempted and wasn"t summitted until 1981. The national park includes three valleys flanking the mountain and is part of the Sichuan Giant Panda Sanctuaries, a UNESCO World Heritage Site. In addition to giant pandas, the sanctuary is home to the red panda, the snow leopard, the clouded leopard, and between 5,000 and 6,000 species of plants.Desktop Version
A towering view of the Pale Mountains
A towering view of the Pale Mountains
Behold the Tre Cime di Lavaredo, some of the most iconic peaks of the Dolomites range in the Italian Alps. The Dolomites, aka the "Pale Mountains," are named for the light-colored stone (dolomite) of the jagged range. This is the view from the highest point of a trail that encircles these three dramatic peaks. Usually mobbed with tourists in the summertime, autumn and spring offer a chance for a more tranquil amble along the 6-mile trail. The hike manages to reveal one stunning view after another with each turn of the route. Along the way, the hiker will pass three "rifugios," traditional Alpine shelters that offer drinks and meals, and even beds to stay the night.Desktop Version
Pining for spring
Pining for spring
Next time you"re out walking amid the verdant majesty of a conifer forest, take a moment to consider the small but mighty pine cone. It plays a crucial role in the trees" lifecycle but has also served as a potent symbol for a variety of human cultures. In many traditions, it"s been associated with fertility and enlightenment, appearing in art from the Mayans, Egyptians, Greeks, and Romans. That association comes from its main job—making baby trees. The ornate, woody pine cones shown here are females, and they"re designed to create and protect seeds. Male cones, which are usually smaller, produce pollen. The female cones open and close their scales to allow for pollination and eventually release their seeds onto the forest floor. But pine cones also open and close in response to changes in the weather, making them a natural barometer.Desktop Version
Beethoven s 250th
Beethoven s 250th
German composer Ludwig van Beethoven created melodies and harmonies we instantly recognize, even in this entertainment-saturated 21st century. Overcoming childhood abuse, hearing loss, romantic rejection, and bouts of depression and alcoholism, Beethoven channeled his stormy emotions into music that compelled audiences to viscerally feel what he felt. In the process, he helped end the regimented Classical era and usher in the Romantic period, when even the most flawed artists were sovereign.Desktop Version

Sandwiched between soaring pinnacles of sandstone, Bastei Bridge is a highlight of Saxon Switzerland National Park. But don"t be fooled by the park"s name because we"re not in Switzerland; we"re hundreds of miles away in eastern Germany, close to the border with the Czech Republic. The name comes from two Swiss artists who visited the area in the second half of the 18th century and felt the picturesque upland scenery was reminiscent of their homeland.Desktop Version

Today"s the first day of the 121st annual Christmas Bird Count, said to be the largest and longest-running citizen science project in the world. For the next 23 days, through January 5, thousands of volunteers around the US, Canada, Latin America, the Caribbean, and the Pacific Islands will join members of the National Audubon Society for this important endeavor in the study and protection of birds. Together, they"ll scour the woods, fields, and lakes of their respective regions (or just watch their bird feeders), to take a census of the individual birds and species they find.Desktop Version

When it comes to beautiful winter scenery, Switzerland is hard to beat. We"re looking at the Gornergrat railway station with the peak of the Matterhorn in the background. One of the last great peaks of the Alps to be climbed by humans, the Matterhorn was finally summited in 1865, capping off the decade or so that"s been called the "golden age of alpinism." The iconic peak is a daunting pyramid of stone and ice, towering just inside Switzerland"s border with Italy.Desktop Version

What are we looking at?
On National Poinsettia Day we"re taking an up-close look at a poinsettia leaf. Although many people assume the red, white, pink, purple, or marbled colors are flowers, they"re actually bracts, a type of leaf that aids in reproduction, usually by turning color as the plant develops true flowers. On the poinsettia, the bracts, surrounding small yellow clustered buds called cyathia, flag down pollinators just as flower petals do.Desktop Version
Mountains fit for a queen
Mountains fit for a queen
Like sentinels standing guard, these towering stalks are flowers of the queen of the Andes, the world"s largest bromeliad—some specimens can grow up to 50 feet tall. This extraordinary plant has adapted to grow only in the adverse conditions found on the high slopes of the Bolivian and Peruvian Andes. To see several of them in bloom at once is truly special, for the queen of the Andes sends up her flowering stalk just once, after a century or so of painstaking growth. A single plant will bloom for about three months, producing anywhere from 8,000 to 20,000 flowers, then die.Desktop Version
What does the fox dream?
What does the fox dream?
We"re sure you could just squeeze this snoozing Arctic fox like a stuffed animal, but we wouldn"t advise it. These cute little fuzzballs can be ferocious hunters. In fact, the Arctic fox is one of the most prolific predators on the tundra, preying on lemmings, voles, rabbits, birds (often with a side of eggs), and other small critters that cross its adorable path. But right now, our Arctic fox is happy to curl up with its tail and get some shut-eye—by forming a ball with its body, the fox is exposing the least possible surface area to cold air, helping to conserve heat no matter how low the mercury dips.Desktop Version
It s Computer Science Education Week
It s Computer Science Education Week
Are we looking at some sort of steampunk time machine? Not quite, but these clock-like rotors did help alter the course of history. The action took place during World War II at England"s Bletchley Park, a country estate that served as a top-secret facility. An assembled team, including the pioneering computer scientist Alan Turing, developed this device, known as a Bombe machine. It was instrumental in cracking the Germans" "uncrackable" Enigma code, which was used for encrypting secret messages in German war operations. The Enigma code was itself generated by a rotor-driven machine that re-scrambled the code each day—so the Bombe mirrored those mechanics to keep up with the changing encryption. Insights the Bombe and other programmable machines provided into enemy military plans helped to speed the Allies" eventual triumph—some even argue that the codebreakers" efforts won the war.Desktop Version
A fortress in the sky
A fortress in the sky
Beginning as a lone watchtower high in the Apennines of Italy in the 10th century, the fortress called Rocca Calascio gained more heft over the next few hundred years. A quartet of additional towers and heavy walls were gradually added around the first tower. These fortifications made clear that Rocca Calascio was ready for any military rivals who might scale the slopes from the valley below to attack this garrison. The fight never came. The ruins you see here are not battle scars but the result of a powerful earthquake. By the early 1700s, Rocca Calascio was abandoned, but it can still claim the title of highest fortress in the Apennines—and some of the most spectacular views in all of Italy. In fact, filmmakers have chosen the site for several movies, including "The Name of the Rose" and "Ladyhawke."Desktop Version

A hidden jewel in Croatia
A hidden jewel in Croatia
Today we"re walking out into the winter wonderland of Plitvice Lakes National Park, the oldest and largest national park in Croatia. More than a million tourists per year flock to this central mountainous region, renowned for its cascading waterfalls and 16 turquoise-colored lakes. These wooden pathways meander for miles around and above the lakes, beside waterfalls and over streams and rivers, which disappear into the moss-covered earth only to burst through again somewhere downstream. In fact, the lakes are all interconnected by underground flows and are separated from each other by natural dams of travertine.Desktop Version
A cozy winter village
A cozy winter village
When snow blankets the steep slopes of the Pyrenees—the mountain range that forms a natural border between Spain and France—the cozy Spanish village of Benasque offers a cheerful refuge on a winter"s eve. Beautifully preserved Romanesque and Renaissance manors and churches line the narrow cobblestone streets, and it"s easy to feel as though you"ve stepped back in time. Aside from these cultural charms, most visitors come to Benasque for outdoor adventure. Surrounded by the highest peaks of the Pyrenees, the Benasque Valley receives heavy snowfall and is a popular skiing destination. Summer attracts even more visitors to the area, when hiking, mountain biking, paragliding, and river rafting are big draws.Desktop Version

Nestled at the foot of Mount Tampa in the Southern Carpathian Mountains of Romania, Brașov is a wonderful example of medieval Europe"s intersecting cultures. Founded by Teutonic Knights, settled by Saxons and Hungarians, and influenced by the Ottoman Empire, the Tartars, and the native Romanians, the city"s Gothic architecture and unique cuisine reflect its rich history. The city"s Christmas market is held throughout the month of December and is dominated by a 90-foot-tall, live Christmas tree. The market"s numerous stalls feature food, drink, and local crafts.Desktop Version
Protecting Alaska
Protecting Alaska
On this day in 1980, President Jimmy Carter signed into law the Alaska National Interest Lands Conservation Act, which converted massive tracts of Alaskan wilderness into protected land. That single act 40 years ago doubled the size of the entire National Park System. Alaska"s eight national parks cover more than 54 million acres. The Cove of Spires, shown here, is just one of the dramatic glacial landscapes that you can experience in Kenai Fjords National Park. Located near Seward, the park is home to 38 glaciers, which cover over half the park"s area in ice—though climate change has reduced them drastically over the last decades.Desktop Version

These common terns sharing a fish have the right idea for today, which is Giving Tuesday. Held annually on the Tuesday after the US Thanksgiving, the global movement serves to encourage acts of generosity during the holidays, when consumerism seems to be the focus for so many. Giving Tuesday was founded in 2012 by New York"s 92nd Street Y in partnership with the United Nations Foundation. Originally observed only in the US, it"s grown into a worldwide celebration of generosity promoted by a newly independent organization. There are several ways you can participate: Donate to the cause of your choice, volunteer your time, or just do something nice—even sharing a fish counts.Desktop Version
A water loch-ed castle
A water loch-ed castle
Located on a small island where three sea lochs meet in northwestern Scotland, the current Eilean Donan Castle is just the latest incarnation of several monastic cells and Scottish clan strongholds that have occupied the tidal islet since the 7th century. The first fortified castle was built in the 13th century to defend against invading Vikings who occupied much of Scotland at the time. An iconic symbol of Scotland, from the 14th to 18th centuries the castle was mostly held by the Mackenzies and defended by the MacRaes, both storied clans of the Scottish Highlands. The castle was destroyed in 1719 by the invading British Royal Navy during the Jacobite Uprising, but was rebuilt along its earlier design in the early 20th century by Lt. Colonel John MacRae-Gilstrap.Desktop Version
New Zealand s loneliest mountain
New Zealand s loneliest mountain
According to the legends of New Zealand"s Indigenous Māori people, the lonely Mount Taranaki wasn"t always lonely. Taranaki, the story goes, once lived among other mountains in the North Island"s center. But Taranaki feuded with the powerful volcano Tongariro over the love of the pretty peak Pīhanga. In their epic battle, the now flat-topped Tongariro lost his head but emerged victorious. The vanquished Taranaki wandered west, cutting trenches as he trudged to the shore and filling them with lovesick tears to create the region"s rivers.Desktop Version

Happy Thanksgiving from an expert face-stuffer
The Siberian chipmunk is the only species of chipmunk found outside of North America. Its native habitat ranges from across Russia to northern China, Japan, and Korea. Though Siberian pine nuts are a favorite meal, these little rodents will eat nearly anything—seeds, fruits, insects, even small birds and lizards. Our ravenous friend here in Hokkaido, Japan, is gorging on inflorescences, or clusters of flowers. A chipmunk can stuff a surprising amount of goodies into its cheek pouches, which can stretch to three times its head size—imagine how ridiculous we"d look if our stomachs were as forgiving.Desktop Version
