West winds transporting lots of snow at ridgelines from the divide all the way up. I triggered 3 avalanches. One was small. The second propagated about 300 feet wide. The third was near the top of Bridge Canyon under the cornice and was about 100 feet wide.

All were breaking on softer, low density snow under a slab of wind drifted snow about 8-12 inches thick.

Below ridgelines, there was very little wind and few avalanche concerns.
