CT and ECT failed at 13 taps, both Q2, sudden collapse, full propagation in the ECT. When I pulled the whole cohesive block off the failed layer, a second layer about 15cm thick appeared when it hit the ground and sheared off; a very planar interface at 53cm above the ground. Not sure if this was due to wind, settled snow, or a density change in the storm. But, it looks like shallower slabs may be able to be pulled out with more load, which may step down to the problem layer above the stout crust.

Pole probing on south aspects revealed only new snow on the ground, maybe 30cm, no crust.
