Location:

Shuksan Arm

Comments:

Second hand report - remotely triggered by skiers/riders visible in photo. Old crust surface visible in photo. Possible that at this elevation faceted surface or near surface crust-facet layering less affected by warm precipitation on 1/30 that wetted OSS at NTL. Uncertain if it released at OSS or at crust-facet layering below.
