A man in the US has managed to survive nearly three days trapped in his pickup truck by eating cans of frozen beer.

Clifton Vial couldn't dig his truck out of a snowdrift in western Alaska.

He had no food or water and no coverage on his mobile phone.

The 52-year-old was eventually rescued and the ordeal left him 7kg lighter.
