My eye's aren't good, not to mention I'm retarded. So can someone tell me if the line at midslope on the snow is the crown of a slide? Isn't this pretty steep for such a slide? Anyone have any real information about this?

i'm no avy expert myself, but it does kind of look like a very small slab. it looks like Chair Peak too. when did you take the photo? we had a nice big spindrift come by on Saturday when we were there...

It looks like wind sculpting to me. Look at the pock marks on the left side.

 

Yeah, we crossed a bunch of these flutings when we did Chair a few weeks back.

Um, well, max didn't take the picture...because I'm not max. Where he is hosting it from.

 

To me, that fracture line two-thirds of the way up the slope looke like a small slab break (a sluffalanche, a slabalanche). The slope there is pretty steep (60-70 degrees), meaning any snow accumulation above a crust will slough off. I'm sure lots of windloading goes on there. And in the course of a day or two or three on windy days, enough can accumulate there to slough off (i.e., gets too heavy to maintain adhesion so slides away).

Hey, sorry about that. I didn't mean to imply I took this pic and I should have credited you with the photo.

 

I guess what struck me about this photo is that it's good evidence that wind slab is different than wind deposition.

 

Speaking of wind deposition...

After a brief analysis my best guess is that a small piece of cornice or ice (or Joe Simpson) blew off the top of the slope, landed mid slope and triggered a point release slide and caused the funny shaped crown.

the picture just looked like low density snow sloughed off of the ice underneath. I wouldn't call it an avie really, just an area where gravity pulled the snow off of steep ice.
