Poor Snowpack Structure

Upper back bowls of Mill B are always a suspect place for me with lingering deep slab instabilities; they are high and cold, rocky with lots of rollovers, wind scouring, etc. Used the large slide in yer crazy and the bowl lookers left of it as a safe route, but dug a quick pit on the lower flank of the slide after crossing a portion of it and feeling things to be quite hollow with pole plants. Found the new February slab to only be about 2 feet deep, thinner than elsewhere. Old faceted snow below that was strengthening, now mostly finger hardness, with only stubborn dirty shears. However, continued pounding on the shovel beyond the standard 30 steps for a CT/ECT, brought the whole column out to the ground on large depth hoar. Also, snow around rock bands in the areas that have slid is a foot of facets over rock, and would not be surprised to see a repeater there. I don't think Thursdays storm will enough load to affect deeper buried week layers, or even much on the surface (see above about crust/facet sandwhiches), but the weekend's may. Moderate tomorrow seems likely, rising through the weekend.
