An interesting one was the size 3 avalanche that had run off the SE face of
Mt. Swanzy (you know the inviting slope that everyone sees from Sapphire
Col). It likely occurred near the end of the last storm cycle (weekend of
Nov.12/13) and ran across the entire breadth of the slope (@80-100m) and
under the rock band it appeared to step down to the old summer firn (old
snow) surface, it ran across the flats below the face for several hundred
meters.
This could have run on the October rain crust but hard to say from that
distance.
The other is that the surface hoar (@3-5mm) in the Asulkan valley is intact
from below treeline and into the Alpine except where there has been
significant wind.
Cheers,
