General Comments

Party of two skiers approached the edge of the ridge, which was slabby/cracking snow. Wind loading from the SW out of dry fork. Sympathetic releases from skier on the ridge, Cracks ran back on the windward side of some vertically building cornices several feet, almost back to the old scoured snow. 2 small slabs 100 feet across released on either side of a very subtle ridge.
