Comments
Sharp Crown still visible under cliff band. Likely triggered by a Natural Loose Dry during the high PI rates on Monday. As the Loose Dry poured over the cliffs from above, it appears that the Storm Slab Avalanche was triggered. Also likely that there was graupel pooling involved as the Crown was directly under these steep cliffs, and the first part of the event had at least 4 inches of grauple in many locations. Avalanche was SS-N D2. Only significant avalanche observed in the Snake Creek drainage off of he East ridge of Sunset. As observed throughout the region, widespread Natural Loose Dry Avalanche Cycle was evident on all steep terrain on all aspects with one digging down in the NE chutes directly off of Sunset Peak.
Riding was good on SE and S, but the solar effects came into play by 1130 and there will be a m/f crust on these aspects on Wednesday.
