Avalanche: Turnagain
Location: Seattle Ridge
Rode up to Seattle Ridge to take troubleshoot camera image issues for the Seattle Ridge weather station, take inventory of the new snow and any recent avalanches.
One skier triggered wind/storm slab yesterday in 2nd Bowl. Otherwise, only sluffs and very small storm snow slab avalanches seen.
Avalanche Details
Skier triggered wind/storm slab avalanche on 2/13. Little details. The slab appeared to be around 1 foot thick and quite a wide and linear propagation. It did not step down from what we could see. There were a few areas the debris triggered small pockets of additional soft slabs within the storm snow in the alders lower on the slope.
Weather
Mostly sunny with some high clouds.
Temperatures near 20F
Calm wind
Snow surface
16" of soft settled snow from Wednesday 2/12.
Snowpack
We found that Wed's snow was bonding to the old snow surface. No cracking or shearing in Wed's snow.
We did not dig a pit today and spent time looking at several locations and any signs of recent avalanches. Other than the avalanche reported above, there were no signs of large slabs that were either triggered by people or naturally. There were a handful of smaller old wind slabs from Wed's snow however.
