The snow pack on the backside of Cascade around 9000' on N-NW slopes is very thin and rotten. I found the average depth a little below the ridge line on a NW slope was only 43cm deep. There is a 3-8" thick pencil hard isolated wind slab capping Fist to 4F hard 1mm facets down to 5cm above the ground. The old snow from 5cm down to the ground is a knife hard crust of 3mm facets. Roughly 20' below my pit the wind slab ends, and it is just half a meter of junk to the ground. The area was still within the tree line, and above tree line wind slabs become more wide spread and consequential (they are not connected across the entire drainage, but do cover each slope. Test results yielded expected failures with that type of structure, but didn't show much energy upon failure (CT12SC@25cm and ECTP14@30cm). The snow pack on the Big Springs side of the ridge on a NE slope was just over a meter deep, and contained multiple wind slabs with less dense snow sandwiched in between them in the upper half of the snow pack. Winds have been loading from the W-NW the past few storms, so NE- ESE slopes currently have more substantial wind loading on them. All and all the snow pack has adjusted to the old snow, but the addition of a new load will overload most of the shallower NE - N slopes with out a wind slab. I would suspect that areas that have these isolated stout wind slabs will be able to bridge a substantial amount of weight prior failing. Southerly slopes around 8000'-9000' have formed a MF crust that has 3" of new light density snow on top of it. Once we go back into a substantial warm up these steeper faces with the MF crust will most likely have a round of WL activity on them.
