- Height of storm snow (HST): 45-90 cm (18-36 in)

- No signs of cornices, wind slabs, or storm slabs.
- No obvious signs of avalanche danger including: no observed avalanches or whumphing or shooting cracks.

- Snow pits dug at two similar NE aspects showed slightly different structures and depths, but generally consisted of new storm snow with F-4F-1F hardness sitting atop a mix of rounding facets and ice layers or melt/freeze layers. Failures were stubborn to unreactive. Results from stability tests at two NE facing aspects at 7800 ft:
- Location 1:
- CT17 ↓ 30 cm BRK x 2, CTN
- ECTN17 ↓ 30 cm, ECTX
- Location 2:
- CT20 ↓ 95 cm SC
