General Observations

Followed the typical route from the Richardson Monument parking area to the main riding area at Summit. Visibility was poor so after reaching the first plateau we went back down to lower country. We observed wind loading on north and NW aspects that created an extremely unstable slab between 8-12″ thick. This resulted in at least 2 small snowmachine-triggered avalanches on slopes as low angle as 27 degrees. The terrain explored was low consequence terrain so no one was caught up in the slides. There was further evidence of cornices breaking off and causing small slides in the same area. Winds were high  and the additional snow from the storm is likely to exacerbate avalanche conditions, although temperatures did rise significantly during the snowfall which may help with some consolidation of weak layers.
