Ultimate Survival Alaska

In the first leg of the competition, four teams battle their way to the summit of Mount Gerdine.

Dropped near the top of a towering mountain peak, teams must descend in any way possible.

The teams must follow their leaders' strengths if they want to get to the LZ first.

The Alaskan vets attempt to ride the Turnagain Arm bore tide, a massive title wave, to the LZ.

To reach extraction, the adventures traverse mountains, canyons, glaciers and an iceberg-filled lake.

Fed up with his team's lack of communication, Sweeney goes rogue, leaving Kasha and Cluck behind.

Tensions run high on leg seven and one injured team member contemplates quitting the competition.

The teams are tasked with building log rafts that will withstand the punishing Tazlina River.

The hunters become the hunted, as teams face their fiercest challenge yet: Kodiak brown bears.

The teams continue the adventure in the Kodiak Islands and choose between traveling by land or sea.

Eleven legs in, the competitors are starting to feel the pain as Alaska pushes them over the edge.

With two legs to go, the pressure's on to snag one of the few remaining wins.

Beaten down after weeks in the Alaskan backcountry, the competitors brace for one last battle.
