    Specific to steep terrain. Ice climbers should pay particular attention to this as entrenched loose snow may have the volume to knock climbers off their stance. Solar input has the potential to trigger this problem.

Snowpack Summary

The top 30cm remains unconsolidated except where exposed to wind where soft slabs have been formed. The snow depth is variable at all elevations. There is a crust/facet layer distributed through the region in the mid-pack with mixed reactivity and a weak basal facet/depth hoar layer at the base of the pack.

Wednesday's trip to Parkers Ridge noted several loose dry up to size 2 out of steep, rocky solar terrain triggered by solar input.
