Name: Steve Banks
Subject: Irwin Tenure
Aspect: East, South East, South, South West, West
Elevation: 10,400-11,1700

Avalanches: Morning D1 avalanches reliable skier triggered within the storm snow or at the interface of old snow. Minimal propagation, running fast, dry and light. By afternoon aspects from E->W became very touchy with more propagation, stiffer snow and some surprising remote triggers, almost everything steeper than 34° was moving. Still nothing bigger than D1.5 and running within the new snow, but it’s happening….
Weather: OBS all day with heavy snow in the morning (S5) and strong winds in the afternoon. Temps near 20
Snowpack: Snow went upside down quickly. Morning study plot measurements showed 8″ of 3.5% density super fluff. Great skiing. Afternoon measurements showed 6″ additional at 12%. Heavily wind affected. Skiing became very different–stiff and harder to keep the tips up!
