We toured up Green Butte to the ridge between Sun Bowl and Powder Bowl to get some observations on wind slab formation and to gather information about the recent storm. Two to three inches of new snow sits atop a thick supportable crust. The fresh snow below and near treeline shows little to no signs of wind. Trees had large sediment cones showing that the recent warm temperatures and rain have allowed the snowpack to settle significantly. Above treeline, small drifts are forming (3-5 inches deep), but generally, smooth snow surfaces exist in the area. Ski cuts and stomping on small drifts detected no blocking, cracking, or signs of instability.
