Observer Comments

We did not encounter any avalanches or whumphing during our ski. However, we saw several new avalanches across the highway on Seattle Ridge.
Our main observation for our route was all the cracking. We didn’t ski anything too steep, but on most steep rolls and the steep pitch of Common, the cracking led to frequent new snow depth (6-12”) loose slides on the last snow bed surface. There wasn't any cohesion in the slides at all, just deep dry and loose and stopped flowing as soon as the pitch decreased.
