Several sz. 2 slab avalanches observed in side valley above Surprise Lake (sz 1.5-2.5). Hard to determine age but most likely ran in the last few days due to the recent storm snow. Found them on varying aspects, but all triggered ATL. Some settlement occurred during our travels, but mostly in creekbeds and not widespread. No new Na observed yesterday.
