Observations

We dug a pit on at 6440ft on the East aspect of Bullion Peak.

We found easy sudden planar collapses int the storm snow on CT3/4.
We found planar collapses above the 1/13 crust on CT9/11.
We did two extended column tests and found a collapse across the column on ECTP9 and ECTP11.

We observed shooting cracks while skinning on several aspects.
We observed several small slabs (~10m x 5m x 10-20cm) that broke on skin skiing, traversing, and skiing on East, SW, and N aspects of Bullion Peak on our ascent and descent.
