Comments
very sensitive cornice breaking remotely from 10-100 feet away as I walked along ridge. Some settling all along the ridge too. Small cornice breaking off triggered small (50-100 wide by 50-100+ run) avalanches to start all along the ridge as I ascended the ridge line. Avalanches were 8-12" deep, slow moving and stopped within 100' as they slide down ne facing slope. Southwest side of ridge showed no signs of instability.
Comments
Forecaster's comments: I'm betting surface hoar/near surface facet is the culprit weak layer here.... Old/new interface also a good description...... Toby
