Can you spot the hikers in this picture from Great Sand Dunes National Park & Preserve in Colorado? It’s easy to lose your perspective when looking at the tallest sand dunes in North America. A park of year-round adventure, there’s a particular beauty about this special place in winter, when snow hides in the curving shadows of the dunes. Photo by Patrick Myers, National Park Service.

What’s winter like at Washington’s Mount Rainier National Park? The mountain’s landscape undergoes a dramatic transformation. Its colorful subalpine meadows and lush old growth forests are draped with a thick blanket of snow for much of the year. The sometimes dusty-looking glaciers are freshly covered in white and the snow-covered roofs of the rustic historic buildings are rimmed with icicles – creating a picture perfect setting.

This heron at Bombay Hook National Wildlife Refuge in Delaware has the right idea. It’s always nice to find a good perch and enjoy the peaceful beauty of a fall sunset. As urban development increases along the Atlantic Flyway, protected lands for migratory birds becomes even more important. With more than 16,000 acres of forests, fields and wetlands, the birds can find a place to relax; and maybe you will, too. Photo by Tim Williams, U.S. Fish and Wildlife Service.

The winter view of Longs Peak from the Dream Lake Trail at Rocky Mountain National Park in Colorado is an epic sight. The wind kicks up a flurry of snow, sweeping the massive mountain and sending a chill we can feel through the screen. Does this make you want to put on your boots or slide under a blanket?

Denali National Park in Alaska is six million acres of wild land, bisected by one ribbon of road. Travelers along the road see the relatively low-elevation taiga forest give way to high alpine tundra and snowy mountains, culminating in North America’s tallest peak. Called The Mountain by locals, Denali stands 20,310 feet tall. Photo by National Park Service.

In southern New Mexico, surrounding the city of Las Cruces in the Río Grande’s Mesilla Valley, five iconic mountain ranges rise above Chihuahuan Desert grasslands. These mountain ranges and lowlands form the Organ Mountains-Desert Peaks National Monument, which was established in May 2014 to protect the area’s significant prehistoric, historic, geologic and biologic treasures.

Located in the northwest corner of Lake Superior Isle Royale National Park in Michigan is the place to go for solitude. The park is an island of roadless backcountry reachable only by boat or seaplane – making it the least visited national park in the lower 48 states. Photographer Carl TerHaar captured this moonrise from Pickerel Cove, one of the islands’ campgrounds that consists of a narrow ridge accessible by small boat.

On a quiet morning 75 years ago today, Imperial Japanese forces attacked the United States at Pearl Harbor, Hawaii. More than 2,400 Americans were killed and 1,100 more wounded. Twenty-one ships of the Pacific Fleet were sunk or damaged, including the USS Arizona. Shocked and angered by the attack, the country joined the Allied forces to fight World War II, inspired by the call of “Remember Pearl Harbor.” A moving reminder of the service and sacrifice of those who fought, the USS Arizona Memorial is jointly administered by the U.S. Navy and the National Park Service.

Whoa! Sunlight creates rainbows from the spouts of two gray whales at Channel Islands National Park off the California coast. The waters surrounding Channel Islands are home to more than 27 species of whales, dolphins and porpoises – representing about one-third of cetacean species found worldwide. If you’re hoping to catch a gray whale sighting, try visiting the park during mid-December to mid-March when they migrate. Photo courtesy of Larry Goldman.
