Observation: Turnagain
Location: Lynx Creek
Johnson Pass TH to Lynx Creek.
Obvious signs of instability
Observer Comments
We were able to trigger a small test slope (wind loaded). Localized cracking relegated to the new/ old storm snow interface.
Weather
32*F at Johnson Pass (N) parking lot. Snowing ~1-2cm/ hr. Moderate winds from the NE. Storm day!
Snow surface
6-10" storm snow, increasing in depth with elevation. As noted in the Fx this morning, storm snow came in upside down.
Snowpack
Focused question: How is the storm snow bonding with underlying layers?
Loc: Lynx Creek, 1900', NE, 29*slope.
Pit results were mixed between three groups. Two groups getting no results at the new/ old interface. One group seeing propagation. ECTPV x 2 (Q3) at new/ old interface.
Note: One group noticed the MLK BSH layer about 40cm down (ECTP26, Q3) in one pit. Aside from this one ECTP result, it seemed pretty stuck.
Given that storm snow came in upside down, results on test slope and ECTPV x 2, we determined new snow is not bonding very well to the old (wind buffed) surface in places where a (cohesive) slab exists.
