Day Two of the Storm

Well over a foot of snow had fallen at Bunny Flat yesterday afternoon since Monday's storm started. Blocky, slabby windrifts over 2 feet deep have formed along ridges. Cracks and blockiness in new snow indicate potentional wind slab and storm slab problems. The concerning weak layer residing within the snow that fell Saturday was not a concern at the elevations where column tests were conducted. Hard to no results were seen at two different, but similar locations. This weakness most probably exists at higher elevations where the crust that formed Sunday is thin and breakbable.
