2/22 snowpack notes
Slope test at 30 degrees
CP Q2 fracture at CT12 fracture at dense facets
SP Q1 fracture at CT22 fracture at thin layer of facets 22cm slab ruled as stubborn slab problem
4 CM of consolidated snow followed by . . .
Relatively firm (1F-4F hardness) new wind slab on the surface with variable scouring to older surface. These new slabs were over a slightly softer and less cohesive layer, providing a structure conducive to instability, but this new layer was . . .
See SnowPilot profile for snow structure. We dug down to the February 8 ice crust and did not go further. While our we did see a failure in a thin layer of graupel in the surface slab (CT11), we felt our ECTX was more representative of the snowpack . . .
very reactive slabs varying in depth between gulf of slides and boot spur were not everywhere but close to steep headwalls, they were very deep and very soft on top of a very stable much more dense slab.
Triggered a small slab over a convex roll in the slide. The slab broke over a firmer wind slab, approximately 10ft wide and ran for about 30ft.
After CTM, Q1 results we observed an ECT14 40 cm down on a visible layer of graupel about 10cm thick (4F). The slab was P-
Ski jump test over pit, 1 foot slab with fractures extending past pit
Observed HIllman’s runout from the Tucks trail late in the day on Thursday the 14th but wasn’t safe to approach the runout until Friday the 15th. Some blocky debris in the dogleg appeared hard but a closer look on Friday revealed mostly softer debris . . .
Snow slope under and south of Lions Head Rock in Tuckerman Ravine. Broken small trees, debris heavily weathered and visually subtle. Elevation 4250 ft, slope angle 36 deg, facing 186 deg S. Timing is a guess, but may have ran during the snow-wind . . .
