Avalanche: Turnagain
Location: Lynx Creek Drainage
Took trail from Johnson Pass trailhead up into Lynx creek drainage. Poked into some side drainages as well. High point was 3,200′.
One very large natural avalanche that appeared to have occurred on Friday during the end of the storm. This looked to be a series of wind slabs formed by the strong winds on Friday.
Avalanche Details
One very large avalanche on the east side of upper Lynx Ck Drainage. Likely released Friday during the very strong east winds. This looked to have been triggered by a natural cornice fall that triggered a series of wind slabs. Debris filled the creek below and ran a short ways up the other side. Crown depths looked to vary from 1' to 6'.
There were some other small natural wind slabs seen as well from Friday, but much smaller.
Observer Comments
No red flags seen today, other than the natural avalanches from Friday's storm.
Weather
Overcast to broken skies. Hard to see most the day.
No precip, calm winds in the drainage.
Temps around 37 in the parking lot and upper 20'sF at 3000'.
Snow surface
Around 4-5" of wet snow at parking lot from Friday. This transitioned to around 5-7" of moist snow at 2,500'. Above 2,000' the new snow was highly wind effected and wind crust/slabs were prevalent.
Snowpack
We did a lot of slope testing and hand pits to assess the wind slabs formed yesterday, Friday. We could not get anything to crack or break, it seemed where we were the wind slabs were stuck fairly well to the pre-existing surface. That said, we did got venter into the steep upper elevation terrain - high point 3,200'. The new snow was quite moist and dense all the way to 3,000'.
There were no signs of avalanches from Friday stepping down to deeper weak layers. A week ago, this was not the case, so that was good to see. We did not dig deeper than the recent wind slab problem.
Large series of wind slabs on the westerly face of Lynx Ck - released sometime on Friday 2.25.22.
Looking up at the upper Lynx Ck Drainage - not great viz today...
