So I rode Excelsior yesterday. Man it was REALLY deep. Like 5 feet total new snow. We didn't ride anything that was high avy danger except We did ride one open face for just a couple pulls to test some clutching which was the main reason for the ride. This spot was well under 30 degrees then rose sharply up to maybe 45 degrees. That said we didn't see ANY avy sign at all. I'm wondering if the snow pack is so heavy it has collapsed and bonded the snow pack in the area we rode. BE CAREFUL!
Avy danger is really high right now.

Avy danger
Yes at some point I'm pretty sure you can bury weak layers so deep there not a threat. With that being said within a few miles of there. The Mt. Baker patrol was able to produce slides estimated at 5-7' off of Shuskan Arm Monday morning on a lee aspect that has been continually wind loaded during this storm cycle.
Now that is some crazy ****!! 5-7 feet deep Slab

I popped one today, luckily it was only on a 20ft hill, but it was still an eye opener.
It was mentioned in the forecast discussion that regarding the persistent slab danger, a slope could be ridden several times before letting go down to the deep weak layers, and to not let other tracks make you feel safe.

There's a video on youtube where guys hammer a hill for awhile and have no issue than try and double up and whammo it cuts loose.
Thought i would pass this along.
