No signs of instability.
Observation: Turnagain
Location: Seattle Ridge
Rode up Seattle Ridge to clear off the weather station anemometer (wind sensor) and then take a look at the top meter of the snow pack and any wind slabs issues.
Observer Comments
Weather
Obscured Skies until the afternoon, then some partial clearing and a little bit of sun. Light variable winds with a few gusts along the ridge from the east to around 10mph. Temperatures were in the mid 20s F.
Snow surface
3-4” new snow from today.
Below this, around 5-10” of soft settled powder over firm snow (old wind affected surface).
Snowpack
Snow pit at 3,000’ on W aspect.
Snow depth 3 meters. Wind loaded location.
CTX - no weakness found in top 120 cm. The stellar interface responsible for the warm-up bowl avalanche was 80cm (32”) below the surface and was bonded. As were any new wind slabs above that. Photo of pit shows 3-4” new snow from today with over a meter of pencil hard snow below.
8-14” loose snow on Seattle Ridge - available for the winds to transport
Snow pit at 3,000’ above Triangle Bowl (-3 Bowl)
Cornice on top of Zero Bowl (Mama’s Bowl) that is right at the top of the up-track.
