Commentaires
Dug a test pit at 1925m on a NE aspect and got some scary results down 30cm on well preserved surface hoar. See snowpack tab. Lots of cracking going on. One settlement remote triggered the cracking (7-8m wide) of a slope from 20m away. It was too supported to avalanche though. Lots of pillows were remote triggered in a similar fashion. All were going on the SH layer down 30cm. The alpine showed widespread wind affect. SE facing open slopes were crossloaded with a 30-40cm deep slab. The top of the north facing chutes seemed windpressed with hard slab has sending down cornice chunks would not leave any mark on the surface. So we skied sheltered SE facing trees for our first run. For our second run, we carefully threaded the needle in the NE facing trees. We ski cut evey steep opening instead of actually doing turns until we reached lower angled trees and a pillow field in which pillows and steeper rolls were easily triggered. The largest controlled slab was a SZ 1.5 roughly 15m wide that ran 40m. A great day all in all but definitely not much safe to ski out there at the moment other than sheltered low angled trees and pillows. One cornice fall had happened overnight on SE Repeater but it did not trigger any slab.
