32°F air temp; light winds but with frequent strong gusts of wind from the SE, high winds on ridgetops.

Lots of wind transported snow making areas of deep, fresh snow, and other areas of thick, strong windslabs, felt collapsing when skinning over wind slabs, often chunks of slabs would break off of skin track and quickly slide downslope.


Dug snow pit at ~3100' for an ECT, resulted in ECTX.
