Observation: Turnagain
Location: Tincan (Below Common Bowl)
Standard approach route, unbreakable crust up to 1600ft, breakable crust above 1600ft to ridge.
Obvious signs of instability
Observer Comments
Recent evidence of wet point slides on all solar aspects. Looked to be from Tuesday 3/29.
Weather
Sunny and clear, calm winds, temps 28-36F
Snow surface
Unbreakable crust up to 1600ft, breakable crust beyond to Ridge; ~2-4cm thick on all solar aspects. Evidence of newly formed surface hoar ~1-2mm. Dry powder with varying depths on polar (shaded) aspects.
Snowpack
Dug Pit at ~2800ft on W-NW aspect below Tincan Common Bowl. Slope angle was ~25 degrees.
CTX. Performed shovel sheer on column after no results; Forceful effort caused planar sheer of storm slab on very thin SH/NSF layer above crust about 160cm deep. Deep Tap provided no results. PST 100/100 end - no result.
Crust layer at ~160cm seemed inconsistent and discontinuous.
SH/NSF layer that shovel sheer caused planar sheer on with significant effort
