Observations

Clear sunny day, calm to no wind to start. Clouds rolled in to block the sun around 2pm.
Skied NW-N-NE aspects, stepped out on solar aspects on the climb. Shallower than expected firmness could be felt skinning and skiing N aspects. Probably from the warm up on Thursday. Small refresh on top from Friday.
High on plummer the surface was sparkly, see photo. Still preserved at the end of the day.
Column test (6000ft, NE) failed CTH on 3 layers, clean shear result at 24cm, 50cm, 78cm in firm snow.
Lots of head size roller balls from Thursday Friday on N aspects. Roller balls but no loose wet slides observed on S aspects. Snow pushed today on N aspects slid as dry sluff or in fans of tiny balls.
