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.

That would be exporting it, as Wright and Lomu have to mine through such obstacles as armed locals and illegal miners to get the gold home.

Assuming death is cheated, Farley's risked-filled adventure either leads to a multimillion-dollar windfall or furthers his family's financial downfall.

The gold rush in Alaska isn't confined to the state's precious ground. It's taking place on the sea ... or more accurately, on the bottom of the frigid Bering Sea. This series, from the creators of the Emmy-winning "Deadliest Catch," follows four gold dredges and their eccentric and driven crews who risk their lives to find as much gold as possible before winter sets in and it's too dangerous to dive.

The survivalists living on Great Slave Lake in Canada's Northwest Territories say it's not man that threatens their existence, it's woman: Mother Nature. "Ice Lake Rebels" follows a handful of residents who willingly face food shortages, dangerous terrain and deadly weather conditions for off-the-grid freedom.
