Comments
Started our tour to Non-Dairy Creamer in Snake Creek around 1000 this morning under warm, sunny, and clear conditions. Immediately we noticed the widespread natural avalanche cycle that had occurred during the previous day's storm on the E and N aspects in both Snake Creek and Caribou Basin. Got a couple good collapses as well as some cracking in isolated areas. We had a very large collapse down in the trees at the base. Skiing was good with no signs of instability. By the time we left around 1400 the snow was wet and rollerballs were frequent on steep slopes.
In our pit at 9500' SE upper 20° we had some concerning results. ECTN 3 on the new snow/old snow interface 70cm above ground. ECTP 7 on a very slim facet layer 65cm above ground and an ECTP 8 on a facet layer 40cm above ground. On this southern aspect there were no near ground facets but an ice layer with a stout snow layer on top. These are some pretty scary results and if we ever get a good load of snow we will probably see widespread avalanches on these layers all around the compass.
As we progress with this poor snowpack structure and have a lot of "considerable" days, its important to remember that considerable means human triggered avalanches are LIKELY and may contain large avalanches in specific areas. The most avalanche fatalities occur during "considerable" days.
