More detailed information about the snowpack: 

A mix of snow conditions existed on Tamarack Peak. On the NW-N-NE aspects, scoured surfaces existed on the open slopes exposed to the easterly winds like the Hourglass (see photo 1). On the more sheltered northerly slopes above 9000 ft, softer snow existed with a layer of more dense snow on the surface. Between 9200ft and 9000ft this more dense snow on the surface changed to a breakable crust (see photo 2). Below the surface the recent snow still rests on top of a combination of crusts and facets; however, extended column tests and other observations showed that fractures are becoming hard and hard to initiate in this area.

On the sun-exposed southerly aspects below 9200 ft. a few inches of soft wet snow existed on the snow surface by 1pm. Below this surface snow melt-freeze conditions remained.
