Lot’s of activity today mid slope in east-facing Cly Creek.  Easy to trigger shallow soft slabs about 6” thick on rolls approaching 40 degrees up to over 100’ wide.  Some small pockets on our 1st run.  Bigger on 2nd and 3rd.  I think the culprit was warming in the morning sun.  Snow did not feel damp. Low consequence in this area, but my partner and I agreed not the day to be on big shots.

2nd photo is cracking on the skin tracks, a harbinger of things to come…….

3rd photo is an example of the monster cornices.

Of note, I skied with a group at the yurt, yesterday they triggered many similar slides on west facing Sesame Street.  They said things were very sensitive, more than today. One stepped down and wound up with a 2.5-foot crown, yikes!

Poles columns yielded shears in the upper 6”.  Also, moderate shears at 2.5’ on compression tests just off the ridge line qt close to 8,000’.

Overall, I think a Considerable Hazard in this area.
