yes
Comment
Snow pack was generally right side up. A foot and a half of fist hard followed by 1-2 inches of 1 finger hard followed by 2 inches of soft/fist hard snow followed by 1 inch 1 finger hard followed by a foot of 3 finger hard followed by ice to the base.
Small 6 inch slab collapsed after the 25ist tap of an isolated column test but did not propagate. Never got anything below to move and couldn’t get the weak layer between the two 1 finger hard layers to collapse.
