Notes
Driving up Bridger Canyon we saw wet loose avalanche across the whole range that ran yesterday afternoon (1/29). Some of these slides appear to have gouged down to the ground, entraining the whole season's snowpack.
There were numerous wet loose avalanches on the south facing wall of Frazier Basin, many of which appear to have pulled out dry slabs lower in the path as they ran yesterday afternoon.
