Snow surface

Soft snow 2" of new
The snow looked wind effected starting around 2000' but was still soft
Ski pen was around 30 cm /1'


We probed at 1200' and found HS: 300 cm, 12.1 crust down 235 cm.
We dug at 2200'. Pit #1, HS: 310 cm, 12.1 crust down 230 cm, dug down 150 cm. Did not dig to the 1.4 new/old interface just looking for any instabilities in the upper part of the storm snow. Found right side up snowpack with no test results.
Pit# 2, HS 300 cm, 1.4 new/old interface, down 170 cm (5.5'), 12.1 crust down 210 cm. No stability tests in this pit. Just looking at overall depth and structure. There was not a weak layer observed at the 1.4 interface. Consistent 1F snow. Thanks to AM for all the digging!
Probing along our route had a number of spots where we couldn't touch ground with our 320 probes.
