When melting ice threatens to flood a town, a 22-ton amphibious mega machine battles the elements to save the day; in the Arctic, the Canadian Air Force relies on a massive transport aircraft to deliver supplies and personnel to far-off places.

The worlds only actual all-terrain vehicle is an Arctic mega monster that can conquer land, snow, and water in dangerous conditions; elsewhere in avalanche country, only one machine can climb deadly mountains and protect a major highway.

See how tourists explore the far reaches of northern Canada and gain exclusive access to polar bears on custom-built rovers, and how the Twin Otter aircraft drops much needed supplies to isolated villages.

Experts use a cutting-edge, all-terrain engineering marvel to access a perilous job site covered in snow; special insider access reveals how this modern marvel helps get the job done.
