The Alaska teams headed to Matanuska Glacier where they had to locate a block of ice. The words "Stillwater Washington" were etched on each block, and a map with various destinations was contained inside it, along with the word "dig." Teams had to figure out where to go next by associating the etched clue with a place on the map (the answer was Lake George, Alaska), and tell that location to one of the five awaiting helicopter pilots before they could commence. At Lake George, teams had to dig for a cylinder and a clue directing them to the capitol building in Lincoln, Nebraska.
