When bears, wolves and foxes are your only neighbors, life can be pretty lonely. Add minus-60-degree days and a constant battle for the most basic necessities, and you have the daily challenges of people who live in remote corners of Alaska. This series takes viewers deep into an Alaskan winter to meet tough, resilient residents as they try to stay one step ahead of storms and man-eating beasts to survive the season. The closest neighbor to Sue Aikens is more than 300 miles away. Eric Salitan subsists solely on what he hunts and forages. Chip and Agnes Hailstone catch fish for currency in bartering for supplies, and Andy and Kate Bassich use their pack of sled dogs for transportation.

Back to the beautiful state of Alaska for another reality-documentary series, this one set in the Arctic National Wildlife Refuge, a protected area home to thousands of native animals... and a handful of people. In 1980, the U.S. government banned human occupation in the refuge, and only residents in seven permitted cabins are allowed to remain. The series depicts the daily rituals of four families living in isolation and contending with bitter weather, frustrating setbacks, and aggressive wildlife in an unspoiled and unforgiving wilderness. The nonconformists include Heimo Korth, the "godfather of the final frontier," and wife Edna; Bob Harte, who has spent 40 years living by his own rules; and young couple Bob and Ashley Selden, who admit that they've survived by trial and error, learning day by day the harsh reality of frontier living.

Tradition collides with transformation in McCarthy, Alaska. The isolated town -- once considered to be the state's version of "Sin City" -- flourished during the Gold Rush but is now home to roughly 40 people, a mix of mavericks, risk takers and rabble rousers willing to brave extreme conditions to live free. While some believe in continuing the town's frontier way of life, others feel the future of McCarthy depends on dragging it into the modern age. Long-standing resident Jeremy Keller fights to protect its roots, while Neil Darish has purchased multiple properties in town and plans to restore its vibrancy. "Edge of Alaska" tells the story of a hinterland at a crossroads.

Discovery Channel takes the ubiquitous survival show theme to the next level by stripping it to its bare essentials. In "Naked and Afraid," complete strangers -- usually a man and a woman -- meet in a very unique way: They're stranded in a dangerous, desolate location, without food or water, and they're completely naked. Each episode follows the adventurers as they attempt to survive on their own with nothing but a personal item and the knowledge that the only prize is their pride and sense of accomplishment. Because there is no other choice, competitors quickly get to know one another -- and their surroundings -- and hope that their instincts, survival skills and intestinal fortitude serve them well.

Extreme survivalists go head to head in a race across the Alaska wild. Using ingenuity, experience and just the gear they can carry in their packs, the participants have 60 hours to reach the finish point of each leg of the adventure -- the series features 13 legs -- and in addition to navigating treacherous glaciated river valleys, barren ridgelines, and high mountain peaks, the challengers battle hunger, dangerous predators and unpredictable weather. There is no grand prize awaiting each leg's winner, other than the pride of accomplishing a grueling feat. For season three, the 12 competitors are divided equally into four teams -- Military, Endurance, Alaskans and Lower 48.

The breathtaking beauty of Alaska sometimes hides the fact its winters can be incredibly harsh, especially for those who live in the state's outlying areas. "Alaska: The Last Frontier" perfectly illustrates this reality, as the series profiles life for the Kilcher family in the isolated community of Homer. For four generations the Kilchers have lived off what their 600-acre homestead has provided, but cultivating that living is never easy. Led by patriarch Atz Kilcher and his brother Otto, the family spends the short summer and fall gardening, hunting and fishing for food, gathering supplies from the land and preparing their animals for the winter. Viewers, who may or may not have a fancy phone by their side while watching on their big-screen high-def TV, also see the Kilchers living off the grid, where running water and electricity aren't daily staples, nor is contact with the outside world. Atz, by the way, is the father of music superstar Jewel.

Each year adventurers make Alaska's mighty Yukon River their home for five weeks. They float downstream on homemade log rafts to sell firewood and other supplies to remote villages.
