A natural avalanche cycle occurred on the east flank of Hudson Bay
Mountain with yesterday's rain. Numerous size 2 soft slabs ran in the
steep terrain, starting at 1800 to 2000 m. On a helicopter check
flight this morning, no recent fracture lines were visible in the flat
light. The temperature was -9 C at 2000 m with moderate wind transport
caused by strong southerly wind. Avalanches terminated well back from
the road.
Soft slabs ran over both the main falls in Glacier Gulch as well as
over the 'Left of Left' falls.
I suspect that there are numerous windslabs that can be triggered by
skiers or snowmobilers. The resulting avalanches will probably not be
overly large, but certainly in the size 2 range. Settlement will be
slow with the current lower temperatures.
