    An 80 cm thick midpack slab sits over a weak, facetted base. On most slopes, recent sun crusts and the buried March 27 rain crust cap this slab, adding some strength. Be cautious in thin alpine areas and where these crusts are weak or are breaking down with heating.

Trace amounts of snow accumulated above ~2000m Saturday. Below this, surface crusts exist on solar aspects to ridgetop and on all aspects at treeline and below. On northerly aspects, 10-30 cm dry snow with isolated wind effect in lee areas of the alpine. The March 27 crust is 30-70 cm deep and extends to about 2500m. Below the settled midpack, there are still facets and depth hoar to the ground.
