The March storm snow has settled to 50cm of 4F to P hard snow over a very thin 5mm thick melt freeze
crust. Under this thin crust there is a layer weak snow consisting of mixed forms with some surface hoar
grains intermixed. The weak layer thickness varied from 2-5cm and was sitting on a crust sandwich
comprised of 5cm weak faceted snow between the February melt freeze crust and the January melt
freeze layer.

Skiing Conditions:
Great soft snow on W aspects and thin breakable sun crust on south aspects.
