Entered Jaws from looker's right to avoid the main cornice just before noon. There was a small cross loaded lip extending out from the main ridge there. Intentionally ski cut and stop right at the lip. Very sensitive. Soft wind slab broke right at skis extending down left and across right taking out entire top section. Slab was 8-12" deep runnning all the way to the bottom where the angle eased significantly and pulled out two more sections under the cliff bands looker's right. While Jaws faces mostly north, the top was also loaded from the SW and had formed a wind slab a bit down off the ridge. I had seen evidence of another wind slab on NE aspect in west Silver but didn't connect it to this trigger since the slope I wanted to ski faces more north and I thought it might be more sheltered. Lucky it triggered so easily.
