That's not a crown, but a big crack running around. There's a few, like bergschrunds, some with some ominous small cracks creeping out from them, though I think only the edges are dangerous.
I've been contacted by a few people about these photos (here and on FB) now. Others have reported some other huge slides in other areas, mostly gullies, hundreds of metres long in some cases. There's just been some fairly unusual snow deposition (2m measured in some sites) and loading mid-late last week and a weak layer formed, releasing on Friday. |
