Season 3 — Episode 10
Bear takes on Hell's Canyon in Oregon — the world's deepest river gorge. He pole vaults his way off cliffs and over streams, before crossing the massive Snake River; taking on powerful white water rapids. Bear scavenges bone marrow from a deer carcass and armed with a spear, goes night fishing. Heading out of the valley he enters the snow line. This frozen wasteland is fraught with danger. Bear takes on steep ice climbs, crosses a frozen lake before falling into the ice cold water, and then picks up the trail of a recent kill and tracks a hunter to get to safety.
