A mountaineer has survived more than 20 hours buried by an avalanche with temperatures dropping to a freezing -15C.
Carluccio Sartori, 54, left rescuers and police officers astonished when he was pulled out of the snow alive - and was even able to have a conversation.
He told rescuers that an air chamber that formed the surface of the avalanche not only provided him with oxygen to breathe but also insulated him from the freezing temperatures of the night.
