On thursday night the region received about 9cm of new snow. Earlier in the week the region received up to 20cms of new snow accompanied by strong southwest winds. Storm snow and wind slabs have formed. There is now around 55cms of snow sitting on a weak interface. This weakness is the December 12th surface hoar/crust/facet combo. What is the tipping point of this weak interface? In areas where this interface has reached its threshold avalanches have occurred. If they have yet to happen naturally, I suspect they are touchy and will react to a rider trigger. Observations suggest there is faceting above and below the buried crust. The crust being a result from rising freezing levels, then the early December dry spell. This crust is widespread and is lingering in most start zones up to 2000m. In short, the upper snowpack is variable and showing easy shears in test results. The avalanche problems exist in the upper meter of the snowpack on this weak interface. Beneath this the midpack is well settled and strong.
