      WELCOME TO THE CASCADECLIMBERS.COM FORUMS   02/03/18

      We have upgraded to new forum software as of late last year, and it makes everything here so much better!  It is now much easier to do pretty much anything, including write Trip Reports, sell gear, schedule climbing related events, and more. There is a new reputation system that allows for positive contributors to be recognized,  it is possible to tag content with identifiers, drag and drop in images, and it is much easier to embed multimedia content from Youtube, Vimeo, and more.  In all, the site is much more user friendly, bug free, and feature rich!   Whether you're a new user or a grizzled cascadeclimbers.com veteran, we think you'll love the new forums. Enjoy!

Avy Question

Recommended Posts

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...

looks like some windslab coming off. it's not too steep, though steeper than usual (hard to tell from photos).

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.
