Wet avalanche activity seemed to be relatively run-of-the-mill loose snow surface sluffs—I didn't see anything particularly large or deep. Wet activity was most pronounced on mid to upper elevation slopes facing the sun. Upper elevation north aspects in the Sawtooths had a dry appearance, but in the Banner Summit zone high norths had rollerballs and a moist look to them.
I suspect that the wet loose surface instability has largely run its course. The big question is whether another night of above-freezing temps will cause any deeper wet slides tomorrow.

North Sawtooths, NE-S-W aspects primarily middle and upper |
D1.5 | WL | N-Natural | Fairly normal wet loose activity. Most slides were D1-1.5. There were a couple that were probably pushing D2 because they were in larger terrain. | ||||

D2 | WL | N-Natural | This was one of the larger wet slides I saw from the Stanley RS, but the size was largely driven by the terrain. | ||||

Banner Summit, all aspects except due north mostly mid and upper |
D1 | WL | N-Natural | Fairly normal wet loose activity. Didn't see any wet slides on upper elevation, due N aspects, but these had some rollerballs. The photo here shows the largest wet slide I saw, on a SE aspect at 8900. | ||||

D2 | U | U-Unknown | Ben saw this on 4/2 from the earthquake cycle. Must have run on a deeper layer near the ground, and the bed surface has since melted out. |
