More detailed information about the snowpack: 

Cold but sunny morning, with widespread surface hoar and near surface faceting below and near treeline.  Went onto to West facing slopes below Wheeler Peak.  Found basal facets and mid pack graupel and facet crust layers.  Near and below treeline our snowpack is settling during this stretch of high pressure.  We continue to get moderate to hard force in extended column tests. Overall the snowpack on west aspects near and above treeline is averaging about 100 to 180cm.  We found a lot of variability in terms of snowpack structure while traveling across these slopes. Below cliffs we were finding graupel layers to be more reactive.  Not every slope had basal facets.   Above treeline recent winds have moved snow into breakable wind crusts.  Better conditions for skiing and riding near and below treeline.
