No doubt the most sensitive areas we saw were the recently wind (cross-) loaded slopes heading north from Alta. Considering the amount of cracking and collapsing we got on the skin track up (mostly s and e aspects), I'm pretty amazed that we didn't trigger slides on slopes around us. We did have to reverse our routefinding a couple times and choose areas that we don't normally travel to stay on scoured slopes. Cracking up to 50 cm deep and 20 meters long- although again hard to really tell with the poor vis. We traveled along the LCC/BCC ridgeline for a while and skied into Silver and then Days. Again I was surprised at the lack of activity in response to cornice drops (active cornice growth hanging over N aspects), ski cuts and skiing of the more northerly facing slopes considering the incredibly prolific cracking and collapsing on the southerly aspects. I did trigger a number of small (15 cm x 10 m crown at the largest), wind slabs on north slopes, but in terrain where I would have expected something more substantial. The wind loaded areas that were not at the tipping point today didn't seem far from it- tonight and tomorrow afternoon should be a different story.
Forecaster Comments: Noted that Andy and party here didn't use/follow the standard uptracks with his head down; instead to be extremely deliberate about terrain choices to move through terrain in a High danger situation.
