Name: Irwin Guides
Aspect: East, South, West
Avalanches: D1’s with ski cuts on everything steeper than 35 degrees failing 10-20cm’s deep on a storm instability, a couple small remote triggers. Paperboy route produced numerous size 1 storm slabs.
Weather: Obscured skies, Snowing S1, strong winds w/ extreme gusts from the WSW, High Gust 74mph. High temp 11F in the study plot 3F at Ridge Top. HST 12″ with 1.2″ SWE at 4pm. H2D’s at 20″ total at 4pm.
Snowpack: Cracking everywhere on the storm instability. I think the instability is when the storm increased in intensity early this morning but seemed to go away in the pm as ski cuts were not producing any cracks.
