Red Flags Comments
Saw one avalanche that possibly happened Thursday night or Friday, looked like just the new snow at ~7k'. Was seeing a 200-225cm snowpack depth from 7700'-8800'. Saw CTM17 Q3 and CTM19 Q3 about 50cm down. Apeared to be on old rounding NSF. The layer that was interesting was fairly well perserved ~5cm graupel layer about 90cm from the surface. No result on CT, but with a little prying pressure popped right out.
