Weather
Mild air temps with thin clouds passing. Winds were calm below treeline, no transport observed.
Snowpack
Poked a number of holes in S and SE slopes between 9500′ and 10,800′. HS ranged from 140cm to 175cm. All surfaces from SE-S-SW became moist today and were refreezing in the afternoon – surface crust ~1 cm thick. Two crusts of concern in the upper snowpack – the upper was generally thin ~1cm with on average 20cm F to 4f slab resting above. The lower crust was ~2.5cm thick with 40-65cm slab resting above. Facets below the second crust were up to 1.5mm in size. Upper crust produced ECTN results at all sites. Lower crust consistently produced ECTPH results below the crust, but locations with shallower HS failed above the crust. Viewed numerous rider tracks on steep, drifted E facing features in the area and snowmobile high marks on steep, drifted SE BTL slope without any results. No collapsing while jumping on numerous small rolls.
Avalanche
Nothing new observed.
