Bear hikes in Alaska as summer approaches and the glacial ice is unstable. He nearly falls into swollen river rapids when his log bridge collapses. Eventually he reaches the coast and tries to paddle out into the shipping lanes on an improvised raft. Of course the raft starts to since so Bear tries to jump on an iceberg hoping to snag a fishing trawler as it goes by.

In his ultimate survival guide Bear goes back to basics, to show you how to find water food and shelter; everything you need to make it home in one piece.

Bear para-glides into the Montana Rockies. After risking his life climbing down a water fall on a rotten old log and rope ladder that is a bit too short he tries to cross a lake on a holey canoe using a make shift kite and manages to make it part way.
