max Posted March 3, 2004 Posted March 3, 2004 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? Quote
kurthicks Posted March 3, 2004 Posted March 3, 2004 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... Quote
iain Posted March 3, 2004 Posted March 3, 2004 looks like some windslab coming off. it's not too steep, though steeper than usual (hard to tell from photos). Quote
Bug Posted March 3, 2004 Posted March 3, 2004 It looks like wind sculpting to me. Look at the pock marks on the left side. Quote
Greg_W Posted March 3, 2004 Posted March 3, 2004 It looks like wind sculpting to me. Look at the pock marks on the left side. Â Yeah, we crossed a bunch of these flutings when we did Chair a few weeks back. Quote
thelawgoddess Posted March 4, 2004 Posted March 4, 2004 it does look like a slab. not too steep given the "right" conditions. Quote
Harry_Pi Posted March 4, 2004 Posted March 4, 2004 Hello avy question! No need to worry, the virgin mary is looking down upon you within the cornice. Thank you fou allow commie to post. Quote
klenke Posted March 4, 2004 Posted March 4, 2004 Um, well, max didn't take the picture...because I'm not max. Where he is hosting it from. Â 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). Quote
max Posted March 5, 2004 Author Posted March 5, 2004 Hey, sorry about that. I didn't mean to imply I took this pic and I should have credited you with the photo. Â I guess what struck me about this photo is that it's good evidence that wind slab is different than wind deposition. Â Speaking of wind deposition... Â megadunes of antarctica Quote
Bronco Posted March 5, 2004 Posted March 5, 2004 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. Â Quote
mounthay Posted March 8, 2004 Posted March 8, 2004 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. Quote
