The picture below shows a hard slab that released on a steep north facing slope at about 9200 feet. The fracture occurred as I traversed across a wind loaded slope and propagated in front of me for at least 30 feet. The 1 foot deep slab released and slid an hundred feet or so but did not step down into lower layers.
