Forecaster Comments

Tons of people were out recreating on Sunday and Monday. Numerous lines were skied and snowmachined without incident. This is good information but avalanches are still occurring infrequently in isolated and extreme terrain. A few outlier avalanches occurred over the past week. One avalanche yesterday on upper Stairstep likely got more wind than reported on the 14th (Arkose winds are always stronger than Marmot) and looks like it failed on facets sitting on a smooth crust bed surface. More info to come.
