Observation: Turnagain

Location: Seattle Ridge

Route & General Observations

Toured the Seattle Ridge up-track to 2500′. We did rescue drills and looked at surface conditions. Also got a good look again towards Todd’s bowl and Tincan in our inventory of paths that have slid this season. Heather’s pit Wednesday showed a very weak snow on a melt-freeze crust in a Cornbiscuit path that had slid. We are concerned about paths that have slid being repeat offenders with a new snow load.

Snow surface

Surface hoar... 6mm-1.5 cm


Did not dig any snow pits. During rescue drill @ 2500' snowpack was 150 cm. Found moist facets at the ground under a 40 cm melt-freeze crust.
There is a lot of scouring and drifting across Seattle Ridge snowpack depth was variable 15 cm to 150cm.
Under the surface hoar there is 4-6" of near surface faceted snow or the surface hoar is on a very firm wind crust or melt-freeze crust that was exposed by the Dec. 21-24 wind event.
