As Drew noted so well, there is quite a bit going on in our thin snowpack:
- at the base of the storm snow is a layer of graupel that falls out of the sidewalls of a pit. It is still easy to get shears at this layer;
- this graupel layer is either on top of a crust or sitting on top of a layer of facets from the Nov 4th storm;
- underneath this is a very variable layering of disintegrating crusts and facets, with chained depth hoar down near the ground.
The two things that concerned me today were:
- found evidence of what appears to be a second remotely triggered slide in Catherine's Area. This was on a steep north aspect at 10,100' and likely occurred during the day on Saturday. (With no reports, we are unsure.) This failed 60 cms (2') down on a layer of facets just above a September heat crust.
- I was also able to get full propagation with extended columns on similar slopes, failing down at this faceted layer near the ground. These were ECTP21/22 Q1.
I think triggering slides on these northerly aspects is becoming increasingly unlikely, but if someone were to trigger a slide - even a small one - it would likely be up to 60 cms (2') deep and will involve lots of buried rocks and tree stumps.
