Observations

Rolling westward over the Pass, I had a little more than an hour to look around between 12:30 and 2 pm. Start zones were mostly-cloudy, but the mountains offered a glimpse once in a while.

Plenty of shallow loose-wet signs at pass-level, and that seems to be the surface story up high as well. The largest slide observed was on Kendall's west slopes. The middle Kendall Peak col (between those that focused the 2010 and 2015 accidents) may have recently slid in a manner similar to the 2010 accident (see photos).

Limited to six images -- if given a seventh, it would show relatively benign loose-wet activity on the S slopes of Snoqualmie Mountain.

Snowbanks at the pass are huge for Snoqualmie Pass. If only the deep-persistent layer hadn't formed..... Turns out that cross-country skiing is rad in its own way.
