Observation: Turnagain
Location: Tincan Common Uptrack
Alaska Pacific University Snow Science class toured to 2300′ to observe how four day old storm snow is behaving.
Obvious signs of instability
Observer Comments
We observed some recent loose snow and storm slab avalanches along CFR ridge, along Seattle Ridge and on south aspect of Tincan. It was hard to distinguish if these had happened within the last 24 hours.
Weather
Clear skies and calm winds all day on our tour, 9:30am - 2:30pm. Temperatures rose from frigid -3F to mid twenties. What a pleasant day in the mountains!
Snow surface
Soft surface snow conditions characterized by 15-30 cm decomposing particles with some near surface facets - except on south aspects that have a distinct suncrust at the top of the snowpack.
1-4mm surface hoar on the surface at all elevations.
No wind impacts at any elevations, nor any noticeable warming at the surface snow during our tour.
High ski quality.
Snowpack
Dug at 2250' on S/SW
HS 195cm
2cm suncrust
15-20cm decomposing snow
Layer of concern: buried surface hoar/facets @ 20cm down from top (CT6, CT13, ECTN13)
25cm of faceted "March drought" snow
"Boring" rounds below that.
Lots going on within the top of the snowpack on south aspects!
