Snow Characteristics Comments

By the time we exited the area there was 14 inches of new snow accumulated over the past two days. Wind speeds were fairly strong on the upper ridge line, not so bad lower down in the drainage. SW facing was starting to develop a stiffer slab by the time of our exit at 2:30.

Comments

Walked up Willow Heights today to try to get a look into West Monitor to see if there was any activity from the storm. Upon reaching the ridge line the heavy snowfall and wind obscured the view into the bowl. Of note was heavy wind loading filling the starting zone of the bowl with impressive amounts of new snow, and the wind blown snow was denser than the snow that was falling. Decided to ski Wills Hill west facing, the snow in Wills was blown into rippled drifts until you were low enough on the slope to get out of the wind. Only instability in Wills was sluffing of the new snow on the steep roll-over at the bottom. Once back on the ridge line got a little better visibility but still could not determine if there was activity or not. The cornices on the ridge line were still soft, and after dropping a soft cornice into the bowl could make out new snow instability in the form of shallow soft slab, have no idea how far it ran or if it ever stepped down. Photos, heavy snowfall, wind texture Wills Hill, Cracking in soft cornice, bad pic of new snow soft slab in West Monitor, Rime in the aspens pointiong west.

Think the hazard was already considerable in West Monitor when we arrived.
