Deep Persistent Slabs
This problem continues to exist at the base of the snowpack, but triggering is unlikely due to a combination of time, settlement and the bitter cold - all of which have combined to lock up the snowpack. It will reawaken once the weather changes.
Be aware of thin areas that may propogate to deeper instabilites.
