Not really a conditions thread but I think it goes in this forum. This past weekend we got about 18" of fresh snow. We have a really nasty rain crust from January that has facets growing both above and beneth the crust. This was a totally sympathetic fracture, I wanted to drop this slope and was digging a hand pit with my partner when it cracked loose about 15' away from where we were standing. Crown ranged from 12" - about 40" deep, probably about 200' wide. Pretty freaky to stand there and watch it all crumble only a few feet from where I was about to drop. As you can see its not steep at all but it did convex a bit and the slope that slid was unsupported with only a few ulders under it.
Some pix to share

you can see our tracks where we were digging a hand pit before it slid

not enough to burry you but enough to pachinko your ass through some trees
