With the final hours of the competition running off the clock, the three remaining teams risk it all for the glory of being crowned champion. It's a cutthroat battle to the top of Mount Augustine a 4,000-foot active volcano in the middle of the open ocean. To reach it, the teams race across 35 miles of punishing white water rapids and unforgiving seas. In the end, the first team to reach the summit of the volcano is crowned Ultimate Alaskan Survivors.
