A medium size intentional cornice drop produced this fracture on a north facing slope at 10,400'.
After a little more provoking with additional cornice dropping this 34 degree slope failed on surface hoar producing a 12" deep slide that was 70' across and traveled roughly 200' downslope.
I was quite surprised to find preserved surface hoar underneath the slab and at this high of elevation.
