On the wind sheltered shady slopes above about 9,000’ the recrystallized snow is topped-off with 1 to 3” of new fluff for enjoyable turning and riding conditions. Other sunnier slopes are a challenging mix of breakable and supportable crusts.
Today’s main avalanche problem was the sensitive new drifts of wind blown snow. The larger drifts averaged 40 to 60’ wide and about a foot deep. The were pockety in distribution, and found both along ridgelines and cross loaded lower in open bowls around terrain features such as the sides of gullies.
