More detailed information about the snowpack: 

Today my partner and I traveled into the BWRA to seek some north-facing trees and to investigate snow totals from this recent storm.  This morning’s weather started with light snow showers and calm winds.  By late morning the clouds dissipated, and sunshine started filtering through.  From where we parked at 8400 ft we were surprised and observed 20 cm of dense new snow.  Continuing up in elevation totals grew closer to 30 cm at 9400 ft.  On this aspect, the new snow was sitting on a stout melt-freeze crust from the recent warm-up.  Throughout our tour, it wasn’t hard to find signs of wet loose instabilities.  On test slopes, we were able to release small wet loose slides with slope cuts, which didn’t require much force and proved to be reactive for a human to initiate.  We also noted storm snow instabilities with some isolated cracking within the new snow.  Witnessing these signs of instabilities kept us off steep terrain features and sticking to shaded aspects.  Once the sun made an appearance late morning, it didn’t take long for snow surfaces to get moist and for the melting process to begin.  On our ride out we noted roller balls in steep, east-facing alpine terrain.
