Tim, Allan and Jasmine learn that hiking from Flower Lake to Hawkins Glacier is no walk in the park. They estimate their journey will take three days as the crow flies, but they have some major obstacles in their way: blizzards, ice shelves, rivers, and the toll taken by their bodies from dehydration. Greg and Bernice have some problems as well at Hawkins Glacier, and Jeff and Elizabeth take a trip of their own to find the mouth of Icy Bay.
