Video: more from The Coldest Journey crew

Regular TopGear.commers will be pleased to hear that The Coldest Journey team are still on course to make their way across the whole of Antartica. They're aiming to be the first people in history to cross the continent in winter (a considerable challenge that has already seen Sir Ranulph Fiennes have to leave the expedition with frost bite).

And they've just sent us this video as an update. While the sun is streaming through the windows of the TG office, they're currently in a blue ice crevasse field - which is unknown territory... and looks terrifying.
