No field patrol has occurred since Wednesday. No avalanches were noted.
Winds have redistributed snow and stripped many areas forming windslabs. The snow overlies a midpack weak layer composed of surface hoar and facets or a melt-freeze crust depending on aspect or elevation. The snowpack is 30-40cm in depth with a weak facetted base. A rain crust exists below 1800m.
