signs of instability!

snow quality was amazing and preserved at treeline. We traveled between BTL to 2100M. We witnessed many storm slab (approx 30-40cm) releases on convex unsupported rolls between 1700m - 2100m on what Im guessing was the Dec 5 SH interface. Lots of shooting cracks and whumpfs were also observed. There was a rise in temperature as sun came out but it stayed below freezing level between 1700m and 2100m for the day.
