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, Alaska, the park is home to 38 glaciers which cover over half the park's area in ice—though climate change has reduced that drastically over the last decades.

New Zealand's loneliest mountain
According to the legends of New Zealand's aboriginal 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.
Now that Taranaki's settled in, the still-active stratovolcano's slopes and foothills comprise one of New Zealand's oldest national parks. Whether or not he's gotten over Pīhanga after untold millennia, Taranaki continues to compete with Tongariro even through modern myth: Taranaki had a star turn as Mount Fuji in background shots for 'The Last Samurai,' while the Tongariro area stood in for the cursed realm of Mordor in the 'Lord of the Rings' films.

What a wonderful window
From planes to cafes, many of us love a nice ‘window view’, but we’d argue that few provide sights as truly spectacular as Nature’s Window here in Kalbarri National Park. Located 485 km north of Perth, the park covers around 186,000 hectares, and traditionally sees thousands of visitors each year to enjoy its rocky terrain and quiet peacefulness.
The main attraction, however, is this sandstone stunner – formed after many years of wind erosion. Find the perfect angle you’ll be able to catch incredible glimpses of the river in the distance and its surrounding greenery. It’s also one of the best places in the country to watch the sunrise. If you prefer a little more adventure, you can take a stroll to the Kalbarri Skywalk that shows off views of the gorge, or enjoy a spot of abseiling, rafting, and canoeing.

Baddest of the badlands
Heading west on Interstate 90, peek out the driver's side as you approach Rapid City, South Dakota, for the first clue you've entered the Wild West: the expansive, layered landscape of Badlands National Park. It's enjoyed government protection since 1939, first as a national monument and more completely after it was upgraded to national park status on this day in 1978. The park protects 244,000 acres of dramatically eroded bedrock replete with fossil beds—as well as the nation's largest mixed-grass prairie, hosting bison, prairie dogs, and endangered black-footed ferrets.
Before it was a national park, Native Americans called the Badlands home for more than 10,000 years. The Lakota had displaced other tribes to control the region by about 150 years ago—the same time settlers from the East were undermining Native power structures throughout the frontier. In response to these incursions, many Lakota in the late 19th century embraced a cross-tribal spiritual movement known as the 'Ghost Dance.' It was a system of rituals—including the namesake circle dance often performed here in the Badlands—believed to impede the encroachment of white settlers and deliver Natives from violence. But those efforts seemed futile by late 1890 as, just south of here, conflicts culminated in the Wounded Knee massacre where US forces killed more than 250 unarmed Lakota men, women, and children.
The conflict and ensuing tragedy is one of American history's ugliest chapters—but it bears reflection during Native American History Month as we ponder the Badlands' past, as vast and multilayered as the bedrock that makes it up.

Languid life on the Lakes
Surrounded not only by the spectacular fells (moors) and pikes (peaks) seen here on the horizon but also lush, rolling farmlands, the lake known as Derwentwater is one of more than 30 bodies of water in North West England's Lake District. Rounder and broader in shape than its fingerlike brethren, Derwentwater is home to several small isles like this one—though the classical estate built here is an unusual interruption of this mostly-natural tableau.
We're seeing the island's boathouse, one of several buildings that a wealthy eccentric named Joseph Pocklington had erected shortly after his 1778 purchase of the island. The main building, Derwent Island House, is set out of view farther back on the woody isle. The estate once included a stone fort housing a cannon, often fired to incite playful 'raids' on the island during regattas Pocklington hosted each year on the lake. Critics of old—among them poet William Wordsworth, who famously loved the Lakes—decried Pocklington's additions as eyesores, but modern-day visitors gladly line up to visit the Italianate estate on the five days a year that it's open to the public.

National Bison Day
If ever there was an animal that deserved some recognition, it's the bison. Since 2012, National Bison Day has been observed on the first Saturday of November to acknowledge the animal's cultural, historical, and economic significance—as well as its remarkable comeback. Bison were once plentiful in North America. Tens of millions strong in the 1800s, they roamed in great herds, helping to diversify and maintain the prairie habitat. They've also played several important roles in Native American cultures. Indigenous peoples have used every part of the bison for food, utensils, and clothing—and they pay tribute to the giant beasts in religious rituals.
Settlement of the American West caused habitat loss for the bison and that, combined with overhunting, nearly wiped out the species altogether—until ranchers, conservationists, and politicians teamed up to save them. In 1913, 14 bison from the Bronx Zoo were shipped to a wildlife refuge to revive the population. Fast forward to today, and more than 20,000 bison roam on public lands in the United States.

Moving as one
After the nesting and breeding seasons of spring and summer have passed, starlings become highly social birds, often gathering in flocks that number in the thousands. These flocks sometimes take the form of a murmuration—when the birds form a group large and dense enough that they appear to move together as a single organism, even if the movements seem arbitrary. Though scientists still don't quite understand how the individual starlings in a murmuration coordinate their tight, fluid formations, the behavior is thought to be a way to confuse predators.
Imagine if you're a falcon on the hunt and you see a small group of starlings—an easy meal if you catch one. But if the starlings spot the predator first, they may form a murmuration, swooping and diving as one, making it difficult for the falcon to isolate and hunt an individual starling.

Birds of a feather
Today is World Migratory Bird Day in Latin and South America, so to honor the occasion we've chosen these flamingos, rising above the Caribbean Sea off the coast of Venezuela. Changes in daylight hours and food availability can trigger seasonal migrations in many bird species, including flamingos. American flamingos like these will migrate relatively short distances, usually to ensure a steady food supply. Found mainly throughout the Caribbean, their range extends as far north as southern Florida.
The nonprofit sponsor of World Migratory Bird Day, Environment for the Americas, focuses its efforts on conserving habitats for the hundreds of bird species that migrate along north-south routes in the Americas, from Alaska and Canada to Argentina and Chile and places in between. Most of these migratory birds use established flight paths called flyways to travel between their breeding grounds and overwintering areas. These aerial highways tend to avoid obstacles such as mountain ranges and oceans, running parallel to topographical barriers and following routes along coasts or major river valleys. Birds migrating through North America follow four main flyways, the Atlantic, Mississippi, Central, and Pacific. Because the birds need adequate food and shelter at stopover points along the way, conservation of habitats through these corridors is especially important to the birds' survival. This year, with wildfires raging across the American West, the Pacific flyway has been especially peril
While October 10 is World Migratory Bird Day in Mexico, Central, and South America, bird lovers in the US and Canada observe this conservation event on the second day in May. But wherever you live, every day is a good day to pick up some binoculars and watch the birdlife outside your own window.

Falling for Tennessee
Although it might not look like it in this image of a tranquil fall day, Roaring Fork in the Great Smoky Mountains National Park has earned its ferocious name. The stream descends 2,500 feet over just 2 miles—a steep drop. After heavy rains, Roaring Fork transforms into a whitewater rush, the sound echoing off the mountainsides. But during drier spells, the stream quiets to more of a babbling brook, as seen here along the Roaring Fork Motor Nature Trail. The 5.5-mile popular loop drive passes waterfalls, well-preserved historic log cabins, and scenic overlooks of a forest that during this time of year reaches its fall color peak, exploding in bold yellows, oranges, and reds. These are just some of the things that make Great Smoky Mountains the most popular national park in the country.

Super Sandy Sweet 16
We're in the Rockies of southern Colorado to celebrate Great Sand Dunes National Park and Preserve's 16th year as a full-fledged national park—though it was a national monument from 1932, and both the dunes themselves and the surrounding valley's history are far more ancient.
The dunes lie at the edge of the fertile, expansive San Luis Valley just east of the Rio Grande's headwaters and west of the Sangre de Cristo range shown here behind the dunes. Humans have lived around here for at least 11,000 years. But that's just a few grains in the hourglass for this sand field that formed when huge glacial lakes dried up, leaving sediments that were blown by wind against the mountains to slowly form the tallest sand dunes in North America.
