Comments
Soft slabs were easy to trigger within the new snow this morning. While the new/old interface on southerlies seemed to be bonded pretty well there was a slight density change about 4" from the surface. We triggered a few slides all with the same characteristics when in steep enough terrain.
Fx'er note - writing on photo says "Small SS" (or small soft slab)
