Although the state's mention in the title was dropped after the first season, Alaska still plays a major role in Discovery Channel's top-rated show. It follows gold miners, inexperienced as some may be, hoping to strike it rich in the wilds of The Last Frontier and beyond. For their first effort, a crew led by Todd Hoffman and his father, Jack, sunk $250,000 into their dream and came away with just $20,000 worth of gold. The dismal summer was filled with injuries, malfunctioning equipment and constant fighting among the greenhorn miners, yet their serious case of gold fever trumps any talk of giving up and leads to new operating plans in order to salvage their dream. The series also keeps tabs on the efforts of brash youngster Parker Schnabel, veteran Dakota Fred and longtime Yukon resident Tony Beets to hit the mother lode at separate sites.

That challenge doesn't stop Dr. Michelle Oakley from performing her many duties as a veterinarian in one of the most rugged environments on Earth. In addition to running an animal clinic out of her home in Haines Junction, Yukon -- where she lives with husband Shane and their three daughters -- Dr. Oakley also operates a satellite clinic 150 miles away and is the on-call vet for the Yukon Wildlife Preserve, which is about 100 miles from Haines Junction.

"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.
