Informal Snowpack Observations Dug a quick test pit at the top of a small couloir - 9,700' - 340 deg. north. Stiff (25cm) wind board on top of 5-7cm rounded layer on top of 10cm of well developed facets on the ground. Easy to Moderate, Q1 shear results on the 25cm layer. No results on ski cuts - ski pens. were less than 1" while skiing.

Weak Layer & Distribution Slab & Distribution Signs of Instability On W/NW aspects, a well established and fairly widespread stiff wind-board was present. Potential for HS slides if skiers or snowmobilers could effect the windboard enough. A couple of small, Class 1 Nautral slides were observed on North and Northeast aspects.
