At the highway there is only about 20cm of snow, with a melt-freeze crust on the surface that slowly gets thinner and gets increasingly deeper snow on top (up to 10cm), before it disappears around 1200m. Below tree-line we did not observed any cracking, shearing or whumphing all day, although we could see lots of old fracture lines from the most recent avalanche cycle. At tree-line the snow was very reactive on the late January surface hoar down 50-60cm, with whumphing, cracking, remote triggered avalanches (from about 5m away), and ski cuts on north aspects. See "Snowpack" for snow pit results.

Snow conditions were: Powder. Weather conditions were: Cloudy. Riding quality was amazing.

Avalache Conditions: Slab avalanches today or yesterday. Whumpfing or drum-like sounds or shooting cracks.
