"Alaskan Bush People" is a reality-documentary series that introduces the Brown family -- Billy, wife Ami and their seven grown children who -- according to Discovery -- are interesting because "they are unlike any other family in America." The channel says they are so far removed from civilization that they often go six to nine months each year without seeing an outsider. They refer to themselves as a "wolf pack" and, perhaps due to isolation, have their own accent and dialect. The Browns live in the Copper River Valley, where temperatures can drop to 60 degrees below zero, and the family recently relocated and built a cabin there because, they say, their former home of many years was seized and burned down for being in the wrong location on public land.

When bluefin tuna season ends in Gloucester, Mass., it's just beginning in North Carolina's Outer Banks, a perfect opportunity to pit North vs. South in a pro fisherman contest for the ocean's most lucrative prey. Venturing south are the best crews from Gloucester to take on top local fleets in the treacherous Outer Banks, where the weather is more unpredictable than up north, and the seas can be extremely rough.

Top-dollar bluefin can be worth as much as $20,000 each, but a short season and small government catch quota means explosive rivalries surface quickly.

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.

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.

Tanana, Alaska, is like the Pacific Northwest's version of Hotel California: You can check out any time you like, but you can never leave. Well, not exactly, but describing the town as remote is akin to saying the winters are chilly. Located at the junction of the Tanana and Yukon rivers deep in the state's interior, the town has no roads in or out, and for its 200-plus residents, survival in the winter is a daily challenge. "Yukon Men" unveils the people of Tanana, who struggle to find food, heat their homes, and ward off predators. But they stick together, a bond that helps them overcome the harsh conditions.

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.
