Up high, mod-strong SW wind redistributed up to 15cm of new snow, which overlies a crust on all but N'ly alpine slopes where it's on settled dry snow. Below treeline the spring snowpack has undergone several melt-freeze cycles. The March 30th melt-freeze crust is buried 30-70cm deep.
A skier triggered a small wind slab in a lee feature on the north side of Mt Cheops Saturday. Glide cracks have been on the move lately, with a size 2 glide slab avalanche from the S aspect of Mt. Tupper early on Saturday, a size 3 from S Mt. Tupper on Friday.
