We dug a number of snowpits on various aspects and elevations to determine how the new snow had bonded to the old snow, if there were any weak interfaces, and if wind-drifted snow had created any slabs at lower elevations.
There are isolated areas where you may find faceted or rounding faceted crystals at the interface of the new/old snow. These may or may not be associated with a crust and I would continue to dig down to determine how reactive these layers are and if you are getting propagation with snowpack tests prior to committing to a slope. These instabilities will most likely settle out and I will continue to look for them as long as we are seeing avalanche activity.
The N facing pit at 7600 ft was interesting. In the first ECT, it propagated on 28 taps with an audible pop about 2 feet deep. Then the second one wouldn't break at all. This seems so typical of what we've been seeing as we've been hunting for weaknesses in the snowpack.
The danger felt overall Moderate where we traveled. Not game on by any means with the avalanches we spotted. But we felt comfortable traveling under steep terrain. Riding steep terrain involves two steps for me (1) is avoiding obviously wind loaded locations, and (2) is checking for any weak layers within the upper 2-3 feet of the snowpack. There are some isolated, non-wind loaded slopes that could produce a soft slab avalanche. My guess is that these would be maybe 50' wide and 2' deep. These locations seem very spotty but are out there.
