Avalanche. Richard Waller, a senior lecturer in physical geography at Keele University in the United Kingdom, told The Daily Mail that the photo actually depicts an avalanche that cast one large block of ice skidding and rolling much farther than the rest of the collapsed snow, and that the white object is that block of ice. This scenario is also, frankly, pretty obvious to even a casual observer.
Yep, that's what the article stated.
