Snowpack Observations


On tour up Gray Butte and into the Old Ski Bowl we encountered limited visibility, blowing and falling snow, small wind slabs, and places of wind drifted snow and cornices. Some of the cornices and small wind slabs forming on eastern slopes were sensitive to ski stomps, others did not want to budge. Quick hand block tests were hard to trigger on the crust that existed before the series of storms that began late last week. The new snow seemed mostly right-sided-up and was well bonded to the crust in places and not in others. The new snow did not have much cohesion, though it felt that with warmer temperatures storm slabs might become reactive on steeper slopes. Sloughs were produced on small, steep test slopes. Some blocking and cracking was seen.
