Avalanche Details

Several point release slides on east, south and west aspects late morning through afternoon. Didn't notice any activity on north aspects until upper west fork and raven glacier area. First slide was on a north aspect and originated just below a cornice. Propageted about 200' and ran 100'. Second slide was on a west aspect and was 100' below ridge line, propagated est 800 yards and ran 1000 yards. Crown depth at deepest point looked to be 8'. Possibly a heat triggered wind slab as debris pile included refrigerator sized blocks and wet slide characteris at the bottom. Ridge was corniced. Both slides looked to be a few days old.
