Snowpit Observations
More detailed information about the snowpack: 

Average snow depth was around 70 to 80 cm, down to about 20 or less from the lake with rocks exposed in many areas and a lot of bushwhacking to get up to the entrance (via the lake trail). As the snow depth increased in the more exposed areas there was evidence of older wind slabs on top of new ones but any cracking and deeper more concerning slabs were only in isolated pockets. As we got into the col the snow became slightly more variable between firm wind board snow and 4 finger/fist density snow, and the pockets of soft snow increased as the slope got steeper. We did a quick pit at about 10,000ft, roughly 340°, about 28 to 30° slope, which resulted in a non-planar break that made it about 12cm through the column at 14 (CTM14 @60cm) and another non-planar break at 26 (CTH26 @ 55cm). A shovel shear test then broke off a resistant planar layer at 54cm with a moderately hard force, the surface was old wind board snow that has become pen hard rounded facets. After our assessment, we decided to continue up and ski from the top. A ski cut just released some slough and no concerning instability was found. The skiing was on the better side of variable, with pockets of good snow between firm and punchy snow.
