Avalanches:
New storm snow running loose dry less than D1 in size. Minimal cracking out in front
of skis in thread, less than a meter. No collapsing observed today.
Weather: Snowing lightly All day with a couple periods of S1 but not accumulating too fast. Calm
Winds gusting to 19 out of the southwest. Cold temps with highs in the single digits at 12,000′
Snowpack: Today we dug a pit in upper 2 chutes right. HS: 175 W-NW 38*. 12/19, 12/21 & 11/22 PS
structure present. SH noted down 35cm. The 12/19 interface is breaking down and barely a crust anymore. CTN,
ECTX, DTN. PST End 50/100 failing on 2mm Facets between the 12/19 & 12/21 Interface down 50cm. 11/22
interface: DTH SC. PST End 50/100 failing on 3mm facets down 95cm. Both persistent slab problems seem to be
unreactive at this point from widespread explosives testing with both hand shots and large targeted
airblasts. Snow profiles also confirm the unreactive sensitivity.
