Mount Patterson

Steven Noël

Went up Mount Patterson today. Strong overnight freeze made for crusty travel (ski crampons mandatory) that was very slow to soften. 0 boot pen at 2300m at 1300. Many recent wet avalanches to size 2.0 observed, likely from the critical warming on Friday/Saturday (?). Only observed a pair of cornice failures trigger size 1.0 slides in extreme terrain. Bigger slopes felt quite locked up, especially those that survived the recent warming. Bluebird with little to no wind all day.

Snow conditions were: Crusty, Heavy, Wet. Weather conditions were: Sunny, Warm. We rode: Alpine slopes, Convex slopes, Mellow slopes, Sunny slopes. Riding quality was good.

Avalache Conditions: Rapid temperature rise to near zero degrees or wet surface snow.
