Comments
tour was 8:30-1 Maxfield basin to mill a basin. 9900-7000
Experienced a collapse with shooting cracks triggered as my partner approached/ tucked behind some rocks with me. barely detectable crack 8' ahead. there is rough guess 4-8 inches of 4 finger snow on top of 3-4" of 1 finger snow. I think the collapse was below the layer with 1 finger snow that is a base for skis but not sure...
I put considerable for what we observed above 9500. I would think avalanches small and manageable and in localized areas and therefore moderate might be more appropriate, but I am suspicious that the wind slabs may break behind riders and things felt a bit touchy to me.
We toured in a area where wind slabs were likely, which also probably flavors my rating. (lee side of wind, big fetch, high up with no mountains blocking flow)
