BOTTOM LINE
 Comments: Observed quite a bit of natural avalanche activity from the previous few days. Skier triggered wet loose definitely was an issue today on mid and upper elevation solars, though it looked like yesterday was probably the day for naturals.? I easily, intentionally triggered several wet loose D1s and a single D2 below skiers summit dropping into Profile at ~1430. Observed debris from several large wind slab avalanches that either released during or shortly after the weekend's storm. Danger is on its way down but plenty to see out there in the Sawtooths and plenty of reasons to continue to be cautious.
