Written Report:
Observed active cornice development this morning, approximately 8 - 9 AM, on a NE aspect at around 6600'. The cornices along the ridge were soft and easy to break. Temperatures warmed throughout the morning -- the surface snow was deep, delightful powder earlier in the day, then by around 11 AM was heavy, wet, and difficult to ski.
