Weather
Light snow fell for most of the trip, about an inch of accumulation through the day. Visibility for ridgetop winds was obscured but no snow transport was happening on exposed terrain at 11,000 feet
Snowpack
At 11,000 feet on a northeast-facing slope, the total snowpack depth is about 150 centimeters. The February 6-7 storm has settled into a 30 cm thick, 4 finger slab topped with 10 cm of new snow. A 5 centimeter thick, 1 finger hard layer separates the Feb 6 slab and a visible facet layer at 40 centimeters from the surface. No February 3 crust was seen on this aspect but is apparent on most solar aspects. Moderate, propagating Extended Column Test results at this facet layer, ECTP12. January 8 PWL and December 24 PWL are still obvious but unreactive.
Avalanche
Most avalanching was previously reported, with only one avalanche post 2/6-7 storm that was cat triggered, digging into steep slopes above the road. There is a large booter built above the road with a Landing Zone below the road on an east-facing slope. A D1.5 soft-slab appeared to have been triggered in the LZ before the 2/6-7 storm.
