From South Coast Touring:
Mitchell Sulkers
Field of play from 1700--2350m today. New snow over 35cm, with moderate winds at treeline and strong winds at ridge tops.
Alpine conditions more variable with soft windslabs to 50+ cm cutting easily on sharp convexities and moving on buried near surface facets and 190108 Surface Hoar layer.
At treeline and below, no shooting cracks or settlements. Primary concern was storm slabs and snow submersion. Ski pen to 60cm+ in protected areas. Snow was uniform density and skiing was excellent.
From treeline down, we stayed on linear slopes, SW aspect, to 35 degrees. Trail breaking was surprisingly good, though occasionally mid-thigh deep in open trees. @ Tyrol Ski & Mountain Club

Elissa Dawn
Jan 8 and Jan 9 skiing on the Duffy. SE and NE aspects. Calm to light winds at treeline yesterday and light winds with moderate gusts today. Both days were mostly overcast. No recent signs of instability although there were lots of tree bombs today with about 20cm of fresh snow. Great skiing.
