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.

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 custom-built rigs, some barely seaworthy, include an 80-foot barge run by the most successful gold dredger in Nome, Alaska, and a modified skiff that seats only two people.

"Yukon Gold" follows four gold-mining crews who have merely four months in Canada's wild Yukon to earn a big payday. Fighting an impossibly short mining season and with their savings on the line, they work against difficulties to dig the precious ore out of the ground. The crews battle mechanical breakdowns, the elements and 18-hour days under the midnight sun -- all because of gold fever -- and it keeps them coming back year after year for another chance to wager it all.

A fan favorite of Discovery's popular "Gold Rush" series sets out on a new adventure to continue his pursuit of the prized yellow stuff. Dave Turin spent years working alongside Todd Hoffman, earning the nickname "Dozer Dave" because of the many hours he spent bulldozing for gold. In his return, Dave is his own boss, and he's on a mission to find an abandoned mine to resurrect in the hope that old-timers left gold behind. He explores the history of each mine, a search that culminates in Dave picking the one that he can turn into newfound riches.

In Discovery Channel's top-rated show "Gold Rush," gold miners, inexperienced as some may be, hope to strike it rich in the wilds of Alaska and beyond. Some dismal summers result, filled with injuries, malfunctioning equipment and constant fighting among the greenhorn miners, yet serious cases of gold fever always trump any talk of giving up and sometimes leads to dreams being salvaged. The companions series "The Dirt" presents the inside scoop on behind-the-scenes relationships between such miners as brash youngster Parker Schnabel and longtime Yukon resident Tony Beets, as the quest to hit the mother lode never stops.

Before complaining about the market price of Alaska king crab, check out this gripping documentary series, revealing the mortal perils and intense discomfort that fishing crews face on the Bering Sea to catch the delicacy.

"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.
