The one snow pit I had time to dig lacked energy and shears were all Q2 and Q3. The snowpack is not as weak as I expected it to be, but there is loose and uncohesive snow sandwiched between the two ice crusts. The one red flag for me is the lower, continuous 1-2" thick ice crust with the dust in it. There may be enough vegetation sticking through it to provide friction for the snow above, but it is a layer that could easily propagate a fracture a long distance.
