On descent at approx 1700’, second skier jumped on a very small rollover/bump immediately above first skier’s track cutting across the bottom of the bump. Reported slab broke under their feet on the between-crust facet layer, and moved a couple feet downhill to the bottom of the bump.

Snow surface

Approx. 10cm of new snow from highway level up to 1800’. Pretty high density, excellent snowball making snow.


See pit profile below. HS 120cm.
CT12Q3 @ boundary between 1F and 4F in the ‘new’ snow from this past week, approx. 55cm deep.
ECTX. While pulling the column down from the back, slab broke on the between-crust facet layer, Q2.
PST result should be considered questionable. It was difficult to keep the saw moving smoothly up the weak layer, and we did not repeat the test.
