The Arctic is accessible to man only because of ice dogs. As hunters, haulers, and guardians, they have been our vital link to nature for thousands of years. Dogs led the Sarqaq people out of Siberia and, a millennium later, led explorers to the North Pole. As the light returns to Greenland, we arrive in Scoresbysund with a troop of the only companions worth having in this harsh environment.

Mountain men Joseph R Walker was probably the first non-Indian to see Yosemite, in 1833, but not until the California militia entered the valley rounding up the Ahwahneechee Indians was the region discovered. In June, 1864, President Abraham Lincoln signed the Yosemite Grant, making it a California State Park. It became famous through the writings of Horace Greeley and the efforts of John Muir. Cinematographer Dennis Burkhart captures in this video the magnificence of Yosemite Valley (El Capitan, Bridalveil Fall, Half Dome), the High Sierra (John Muir Trail, Tuolumne Meadows, Tioga Pass) and the Mariposa Grove of giant sequoias. The camera catches the wildlife that roams the 1,1170 square miles of Yosemite, i.e. the mule deer, mountain lion, black bear, coyotes, bighorn sheep, and the rare peregrine falcon. This video reveals why 3.8 million visitors come each year and stand before awe-inspiring panoramas they will never forget.

This documentary combines archaeological and geological evidence with tales passed down through generations, uncovering a dramatic history of cannibals, vast stone cities, human sacrifice, and the epic voyagers who colonised the Pacific centuries before Columbus made it to America.

Filmmakers Alastair Fothergill and Keith Scholey chronicle a year in the lives of an Alaskan brown bear named Sky and her cubs, Scout and Amber. Their saga begins as the bears emerge from hibernation at the end of winter. As time passes, the bear family must work together to find food and stay safe from other predators, especially other bears. Although their world is exciting, it is also risky, and the cubs' survival hinges on family togetherness.

In New York's Adirondack State Park, 46 mountains rise over 4,000 feet in elevation-these are known as the "High Peaks." The men and women who successfully reach the summits of all 46 peaks are known as the "46ers."

Marvel at "Old Faithful" erupting, vast rolling forests, abundant wildlife, thundering waterfalls, gurgling hot springs and mud pots, and the beautiful, haunting wilderness. Over 2.2 million acres located in the northwest corner of Wyoming, the great Yellowstone National Park was founded in 1872. The superb camera work of Dale Johnson and Bob Landis captures the natural wonders that captivated the early mountain men of the 1840s: petrified forests, mountains of glass and rivers that cooked fish. Thrill to rare and dramatic wildlife action; an antelope doe chasing a coyote from her young, a grizzly pursuing an elk in a life and death chase, a coyote matching wits with an otter; northern elk migrating in deep snow and bighorn sheep in mating battles. See the Yellowstone fire of 1988, and the charred land in full bloom. Ride with a park range into the backcountry. Enjoy a stagecoach ride to a sunrise cookout. It's all here, the magic of the great Yellowstone.

Riding Giants is story about big wave surfers who have become heroes and legends in their sport. Directed by the skateboard guru Stacy Peralta.

Two thousand square miles, a mile deep, approximately 10 miles wide- no geological feature on earth evokes a wider spectrum of human emotions than does the Grand Canyon of Arizona. It is impossible not to be profoundly moved when confronting such immensity. But it is more than a chasm, it is alive with mule deer, mountain lions, coyotes, bighorn sheep, wild turkeys, blue grouse, blue heron, desert tortoises, and the rare kaibab squirrel, found only in the Grand Canyon. Long before the Spanish arrived, the Anasazi (Ancient Ones) lived here. Included is an exclusive segment, never before filmed, of Shaman's Gallery, a significant Anasazi find of rock paintings in the Grand Canyon area, dating between 2000 B.C., and A.D 1. Established in 1908, Theodore Roosevelt proclaimed the Grand Canyon a parkland and said "do nothing to mar its grandeur, keep it for your children, your children's children, and all who will come after you."
