Observation Details
Noticed a decent surface hoar above 3,000ft. Definitely something to look out for with storm coming in.
Dug a pit at around 3600 ft, approximately 160cm deep snow pack. Snow from last weekend was top 35cm, somewhat consolidated and light crust from wind scouring. 35cm slab sat on a more consolidated layer and hard crust down 80cm.
CT 22 at 35cm last storm, continued to 25 and triggered slab on hard crust.
No propagation on the ECT from top of snow pack, at 21 the top 35cm broke apart but did not propagate. After pulling off the broken chunk we continued to 25 and saw propagation on the hard crust.
If the slab on the hard crust is triggered there is a possibility for a sizable slide. We skied, but decided to stay away from trigger points on the slope where this slab might be more thin.
