Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.
Weather

Sunny with high level clouds, temperatures in the teens to low twenties with calm winds.

Snow surface

Extensive wind scour was observed on all aspects with wind slabs locally deposited on north and northwest aspects, particularly in sheltered areas near trees. Alders were well exposed in the areas we skied and appeared to also be significantly more exposed across the valley on O'Malley gully than before Thanksgiving rain/wind event.

Snowpack

Snowpack ranged from being scoured to rain crust just above the ground to ~10" of fist to 4 finger wind affected snow. 1-2" of soft snow was found at the surface in sheltered areas near spruce stands. Hand pit tests ranged from failing easily on decomposing facets (?) near the ground to breaking on a layer ~6" down. No formal snow tests were conducted. >1-2 mm faces were observed at the snow surface in sheltered areas just east of Blueberry Knoll.
