West South West ridge top winds from 11/30 (see Lake Fork Observations) have produced a stiff wind slab on leeward slopes. There wasn't much snow left for transport from the previous days winds. Wind slabs that formed on leeward slopes were firm and did not extend very far downslope from the ridgelines nor were they very deep. However, a test ski cut did produce a small avalanche (See Photo 1)  We were surprised at how much snow we found on a ENE aspect around 11,800' with snow ranging from 130cm to 195cm's.  This is the most snow we've found this year.  Sun crusts were starting to form on lower angle south facing aspects.

Snowpit from 11800' on the ENE side of Long Canyon at coordinates on the map.

Photo 1: On test ski cut I was able to get a small wind slab to release propagating 10' in front of my ski tips.
