More comments about the snowpack and weather:
We headed to Blacktail to find low angle terrain that hopefully had dodged the crust events that are so prominent elsewhere. 40cm of new snow (4F to F)is sitting on the post Turkey facets (F+), with all snow beneath that locked up--no sign of the rime crust or Thanksgiving crust and associated facets. Much of the glades terrain is still terrain anchored, and it made our first pit hard to read. So, we got out in the middle of the run and found what we were looking for: easy failure of the post-Turkey facets below the storm snow load (CT3 SC 40cm down, ECTP4 SC 40cm down).
