Quick report
We observed point release loose snow slides consisting of the new snow from yesterday only. We also observed roller balls at the end of our tour on east aspects. Grew to bowling ball size. Our assessment of avalanche risk was that 20cm soft snow slides were possible, but stepping down through the 40cm rain crust was very unlikely and we were not concerned about that possibility. We did not see or experience wind stiffened or sculpted snow. The horizontal propagation of these two soft slides surprised us and I don't really understand how such soft snow can act like a slab.
Avalanche
Skier triggered soft slab avalanche on east aspect at 1:30pm around 5800 feet. 20cm crown. 90 feet wide, ran 50 feet. Did not run the length of the slope. Snow movement was slower than the skier. Soft debris. The bed surface is a buried crust about 5cm above the very durable mid-march rain crust which here is about 40cm thick. The debris pile would not bury a person, but the location of the slide could have carried someone into trees. No one was caught or carried. Skier and dog exited the moving snow without incident. This avalanche was very similar in aspect, trigger behavior, width, run length, debris characteristics, crown depth and bed layer to the one Jamie Tackman reported yesterday. It was also quite close in proximity, maybe 300 yards apart. I've included a picture of yesterday's avalanche for comparison.
