Quick report

We skinned up to Point 6 on hard snow. Ski crampons would have been nice. The southeast slope we skied had begun to soften by about noon. In other locations the snow surface remained hard. We dug on a north aspect and found a dry snowpack underneath a surface crust that was supportive to skis, but not boots.

We saw many debris piles from wet loose avalanches on the steep SE aspect from Point 6. These likely ran a couple of days ago.

Several wet loose avalanches from earlier this week

Snowpack

The snow surface stayed hard until about noon, when it began to soften on steep southerly aspects. Elsewhere the snow surface stayed hard, likely kept cool by the wind.

We dug on a northerly aspect at 7750' and found a dry snowpack. Underneath a 5 cm (2 inch) thick surface crust, we found a snowpack that gradually became harder with depth. At 55 cm (21 inches) down we found a 10 cm (4 inch) thick series of melt-freeze crusts, facets, and ice lenses. The ice lenses are most likely from water percolating through the snowpack and pooling on this layer.
