Snowpack Summary
Snow from March 30th and light amounts since has been blown in to an isolated wind slab up to 30cm thick. This has added to the previous slab sitting on a sun-crust on solar aspects and facets on North aspects - buried as deep as 60cm. The snowpack is generally facetted and weak underneath the slab particularly in shallow areas.
