Snowpack Summary

Wind slabs continue to build in exposed lee features. A significant crust (black friday, Nov.23) can be found down 30 to 70cms. A persistent slab overlays this crust and so far the bond appears to be strengthening at this interface. The Halloween crust sits well down in the snowpack at TL locations and as high as 2700m.
