Avalanche Details

We saw 3-4 recent avalanches in the area, see photos. The largest was at about 3500' on a west aspect just north of Moose Creek (USGS map), estimated size from the highway is D2.5. Wide propagation across an upper bowl possibly on a layer of buried surface hoar.

The next two were side by side and partially filled in so I don't know how recent they are. These avalanches were on a south aspect at about 3500' above Moose Creek. Estimated size D2.

We also saw a recent wind slab/cornice fall at about 3000' on a west aspect above Weber creek. Estimated D2.
