Snowpack Summary

20cm of storm snow sits on top of a 10cm thick laminated crust (Nov 11) at tree line, below the crust is 20-30cm of moist snow to ground. Pockets of wind slab exist in the alpine and may rest on a crust where it is expected to exist up to 2600m.  Below tree line is un-skiable due to lack of snow, early season conditions exist at all elevations.

Avalanche Summary

No recent avalanche activity. Field team observed no signs of instability today in the Parker Ridge area.

Confidence

Due to the quality of field observations on Tuesday
