General Observations
Route and General Observations: The UAS ODS Av 2 class traveled by lift to the Eagles Nest, Eagle Crest Ski Area, then hiked to Pittman's Ridge, accessing the S aspect, digging pits at 2850' with avg. slope angle of 28deg, then descending via Heavenly to the ski area.
Red Flags: The group observed isolated R1D.5 Wet Loose avalanches on W aspects at mid mountain elevation on Showboat and the west aspect from Sign Line. We did not observe any other red flags (cracking, whumphing, collapsing).
Weather: Calm with temps in the mid 20sF and clear skies.
Snow Characteristics: Snow surface: Variable snow surface, crusty with pocketed pow; decomposing fragments and rounds. Snow pack: Poor structure with a cohesive slab sitting on a crust 40cm down, with many crust/ facet combos below. At the layer of concern we identified moderate propagation potential (ECTP18 and PST 66/100END), and rated general stability on solar aspects as fair.
