SURVIVORMAN: THE BOREAL FOREST

The Location: Northern Canada
The Ecosystem: Boreal Forest
The Challenge: Spend a week alone in the woods without shelter or provisions.
The Supplies: A handful of cashews, beef jerky, one match, a multi-tool and 50 pounds of camera equipment.

The boreal forest of northern Canada is a vast tract of wilderness stretching from the Atlantic to the Pacific Ocean. It is home to moose and beaver, crisscrossed by rivers and lakes, and is frost free for only three months of the year. Les' arrival coincides with cooling temperatures and the first snowfall of the season.

Les intentionally tips his canoe in midstream and crawls from the icy waters onto shore. Hopping naked around his fire while he waits for his clothing to dry, Les manages to avoid a bad case of hypothermia. In these woods, however, there are dangers more immediate than climate. Bull moose are rutting, making them dangerous and unpredictable. A 1,500-pound male on a rampage could easily put an end to Les' survival challenge.

Shelter is a priority, so Les builds a refuge from logs, boughs and birch-bark shingles. Lake snails are his only source of meat, and unfortunately, he forgot to bring any garlic butter. By the fifth day, Les decides his best course of action is to find his own way out of the forest. He knows there's a highway somewhere to the east, so he sets off using tree moss and the sun to guide him.

Will Les find the road? Will the crew come looking for him? Find out in Survivorman: The Boreal Forest.

SURVIVORMAN: LOST AT SEA

The Location: Caribbean Sea, off Belize Coast
The Ecosystem: Ocean
The Challenge: Survive for a week in an inflatable life raft after being set adrift.
The Supplies: A life raft, bucket, hand pump and 50 pounds of camera equipment.

Living "off the land" takes on a new meaning as Les casts off for a week at sea. Battling hunger, thirst and the Caribbean heat, he must also keep his cameras dry to film the ordeal.

Soon after "abandoning ship," things begin to go badly. The life raft has a few bad leaks and needs constant bailing. It also leaks air and must be frequently reinflated with a hand pump. When a full-blown tropical storm descends on him, Les rides out the gale moored alongside the support vessel. The ocean is no place for senseless risks.

Eventually Les beaches on a deserted, palm-covered island where he is determined to remain for the few remaining days until his "rescue." As a final act before his support team plucks him from the island, Les finds a bottle, sticks a private message down its neck and throws the bottle into the ocean.

After a week alone at sea and then stuck on a tiny island, will his message be coherent? Find out in Survivorman: Lost at Sea.
