Observer Comments

Wind transporting snow!!!
In the Turnagain Pass corridor there was no new avalanche activity observed but a lot of old activity that was easier to see the extent of, due to better light and some crowns were almost more accentuated by scouring. There were a few slides in N Cornbiscuit chutes that we are uncertain about how recent they are. They may have been triggered by the winds or older and not yet observed after xmas storm.
We did receive a report of two small natural wind slabs in Zero bowl and two small snowmachine triggered wind slabs in Warm-up(-1 Bowl).
See Heather's observation from today about the natural wind slab cycle in Summit Lake.
No avalanche activity observed in Lynx or looking towards Johnson

Snowmachiners who traveled farther up reported the bottomless pack until wind effect was felt. Still easy to sink in after breaking through wind layer. Found one layer of buried surface hoar under new snow (December 24th layer). ECT propagated on the ground in facets on alders...
