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.

Back where their gold-mining adventures began, "Gold Rush" alumni Dakota Fred and son Justin persevere in the face of long odds, risking their lives for a fortune they may never realize. Assisted by a team of intrepid divers, mountaineers and bush mechanics, the Dakota Boys explore the white water rapids of McKinley Creek in Alaska, diving deep in raging torrents with a suction dredge. Not only could one wrong move prove deadly, but the guys also face wild animals, extreme temperatures and hypothermia.

Despite striking it rich mining in his home state of Alaska, "Gold Rush" star Parker Schnabel isn't satisfied. He's always wondered if he could follow in the footsteps of his forebears and take on the legendary Klondike Gold Rush trail. Wonder no more. In honor of his family -- especially his beloved grandfather, who always inspired him to push beyond his limits -- Parker attempts to mimic a journey that killed thousands of brave souls in the late 19th century. As winter closes in, he begins the trek across the Coastal Range and works his way to the fabled goldfields of the Klondike. He's joined by his foreman, Rick Ness; wilderness guide Karla Ann, who once worked with Parker as a rock truck driver; and cameramen James Levelle, who has known Parker for years.

"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.

Campers participate in competitions inspired by classic camp games.
