Snowpack: Overall weak and shallow snowpack observed throughout Anthracite Zone. The persistent slab problem was not observed below treeline. At treeline the persistent slab problem produced numerous collapses and visible cracking throughout the test slope area. 11,200′ NE 33* Surface grains: .5-1.5mm Facets/DF HS: 53cm CT 13 SC ECTP 9 SC Both failed 37cm down in 2-6mm depth hoar.

HS showed a shallow snowpack from 15-53cm. Surface hoar was observed on shady slopes below treeline while none was observed near treeline in open wind affected areas.

HS: 20cm Surface hoar observed wide spread on shady slopes.

10,900′ N 30* slope
HS: 35cm. Depth hoar capped by a 1cm melt freeze crust. Facets to the surface.

11,200′ NE 33* Persistent slab structure found
HS: 53cm CT 13 SC ECTP 9 SC Both failed 37cm down in large facets
