Snowpack Summary
5-10cm of soft snow overlies hard snow surfaces of sun crust on steep solar aspects and wind slab at higher elevations. This new snow has seen some wind affect and has bonded poorly to the layers beneath. A new surface hoar layer is down 5cm at lower elevations. The mid pack is well settled but cold weather has begun faceting the snowpack.
