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.
Observation: Summit
Location: Gilpatrick’s
Toured up to a large meadow just below treeline to dig a pit.

Temp: -1C
Wind: Light from the east
Sky: Overcast —> Broken in late afternoon
Precip: Very light snowfall S-1
Snow surface
Approx. 10cm of new snow from highway level up to 1800’. Pretty high density, excellent snowball making snow.
Snowpack
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.
