Snowpack
Snowpack Description:
SNOWPACK/AVALANCHE OBS: Low angle near Washington Gulch TH. Plenty of collapsing without any cracks. Variable slab strength with ski pen at 10cm during the good times and ski pen on the ground during the bad times. Boot pen would have been to the ground all the time. The low elevation slab has certainly been faceting out at these low elevations but the question is how much longer will it take for the slabs to become isolated? HS 60-80cm. Lots of large surface hoar in the valley. SS-N-R1-D2-O at 12,300ft on south aspect of Baldy. Likely failed around Jan 4th and originally observed on Jan 5th. Loose snow avalanche that propagated a shallow slab 100ft wide below Gothic Spoon at 11,300ft, D2. Likely failed Jan 6th and originally observed on the 7th.
