Into the Void Chopper Drop Off The next leg o the expedition leaves the eight explorers on the snow-covered ridge in the Tordrillo Mountains. They will have 72 hours to get to their extraction landing zone that is 25 miles away. Pushing the Limit Dallas Seavey holding onto an ice block. In the third leg of the journey across Alaska, Seavey and the other men will live off the land and use only the gear they can carry to survive. Jumping Over Glaciers Tyrell Seavey jumps over a crevasse. The Seavey brothers team up with Willi Prittie, who guides the brothers through two-ton icebergs, icy rivers and glacier beds. Trekking Through the Snow The eight explorers are trekking through some serious and deep snow that is almost three feet high. The threat of an avalanche is pretty high for these men. In Deep Snow There is at least three feet of snow that the eight men must trek through. Here Willi and Tyrell are doing their best to get through and avoid triggering an avalanche. Team Work Tyrell Seavey high-fiving Willi Prittie. Can Willi keep up with the young duo, the Seavey brothers? Bypassing Avalanches Dallas and Willi team up on the third leg of the expedition. Willi is an expert mountaineer that plans to take a short cut and rappel down the face of the mountain to the valley below in order to avoid a high avalanche hazard. At the Top Brent Sass, Matt Raney, Tyler Johnson, Austin Manelick and Marty Raney at the top of the mountain. Taking a Break Willi Prittie soaking in the sun on the mountain. Setting Up the Tent Dallas, Tyrell and Willi set up a tent to shelter themselves from the 45 mile per hour winds. If you dig and construct a proper snow shelter, it can be plus 30 degrees inside if it is 45 below outside. On Ice Without Crampons The Seavey brothers and Willi look out towards the mountains. Being on the glacier without crampons in a sea of cracks and jumping the cracks is not the best idea. Dallas Maneuvers Through Snow Iditarod champion, Dallas, treks through the snow thankful for having Willi on his team. Willi is known for his summits on big mountains and his knowledge will come in handy for the Seavey brothers. Steep Conditions Willi and the Seavey brothers decide to rappel down the mountain to save time and avoid causing an avalanche. The rock face is very steep and leaves the men taking a leap of courage over the edge. Will they make it safely to the bottom with the 40 mile per hour gust of wind? Window of Opportunity Tyler, Austin, Matt and Marty are the second team to rappel down the mountain and with the weather changing drastically, they are in for a real challenge at this point. Who Will Make It? The eight men divide into three groups to rappel a 300 foot cliff in 40 mile per hour winds. With only 72 hours on the clock to reach their extraction landing zone that is 25 miles away, will anyone be left behind?
