traveled up to 5k' on Avalanceh Mnt via Source Lake and Snowlake Divide . The switch from W to S winds noted late morning, and while most stransport seemed to be on lee N slopes, we observed crossloading and wind effected snow on all aspects. We observed widespread 5-20 cm windslab formation with small skin track cracks - test slopes were unreactive. We were curious about some of the easier, clean hand shears on a mid storm interface about an inch above the Christmas crust . @ 5000ft, W aspect, HS 145 cm, 38 cm storm snow resting above 1cm Christmas crust above 10cm melt forms, above wet grains that went well below a meter down - potentially to the ground. ECTN down 35 cm (mid storm interface - potentially some graupel).
