Started out partly cloudy in the morning. Temps were inverted. Significantly cooler at the road than on ridgetops this morning. Winds were calm.
Clouds began streaming in from the NE around 1pm today. By 3pm light was flat and total white out on the ridge. Winds began to pick up from the NE around 3pm. Back to the parking lot by 3:30. Snowing 1"/ hour (BIG flakes) when we left the parking lot at 4pm.

Snow surface

Solid, supportable melt/ freeze crust at 1K. Thin (5cm) breakable crust from about 1500 -1800'. Snow dries out considerably above 1800' and becomes more wind effected as you gain the ridge. 4-6" soft, shallow wind slabs on the ridge. High point today was 2400'.


Did not dig a pit today. Did watch several snowmachiners high marking and side hilling steep (>35 degree) terrain today in Main bowl without incident. All indications and observations point toward good stability today.
