Arctic Hell
The men pick their route: some take the higher land, some follow the river. Expert climber Willi Prittie leads Brent Sass and Tyler Johnson into the mountains. The bearing they're traveling reaches elevations over 4,000 feet. Veteran mountain man Marty Raney is leading his son Matt and survival expert Austin Manelick through the river valley. Brothers Dallas and Tyrell Seavey navigate along the ridgeline, crossing land with little cover. These born racers are resolute to be the first to arrive.
Episode 02
River of No Return
The men are divided into two groups, building competing rafts. Mountain man Marty Raney is taking charge, building a colossal raft weighing nearly 2 tons which he hopes will be sturdy enough in the rapids. After spending five hours on construction, the five-man crew get on their way, but hunger starts to take its toll. Dallas Seavey, his brother Tyrell and survival expert Austin Manelick are meticulously engineering a smaller raft that's speedy and maneuverable to tackle the turbulent Yukon.
Episode 03
Into the Void
Helicopters leave the eight explorers on a snow-capped summit. The men split into three groups and approach a 300-foot cliff, descend a ravine and traverse eight miles of the Triumvirate Glacier. Marty Raney, his son Matt and Brent Sass take a low route and are the first to cross. Willi Prittie and the Seavey brothers cross far from the icebergs, across 33-degree water. Austin and Tyler bypass the glacier, traveling along the ridgeline. They arrive last and Austin's showing signs of hypothermia.
