Red Flags Comments
Avalanches only consisted of shallow damp sluffs along the Dam Roadcut. I suspect they were initiated from snowplows throwing snow onto the bank below. Other similar steep slopes away from the road did not have any of these sluffs. I did not see any cracking in areas where I do sometimes when things are really sensitive.
Comments

I observed the entire snowpack to be damp below 8800'.  I did not look at the snow higher than that, too much of a blizzard.  Snow temperature sensors on the KALF in Spring City Canyon at 9400' indicate that the pack was damp up to that elevation also.  The sub-surface probe was about 15" up from the ground. (see table below)

Concerns for wet avalanche activity crossed my mind and would've gotten me more excited if I new the temps weren't about to cool off dramatically.
