Mooiiist snow

CBAC 2020-21 Observations

Zone: Northwest Mountains

Location: Mt. Owen

Date of Observation: 11/18/2020

Name: Zach Guy


Subject: Mooiiist snow

Aspect: North, North East, East, South East

Elevation: 10,500 – 12,800′


No recent activity

Weather: Unusually warm temps. Strong SW winds but no snow transport. Scattered clouds.

Snowpack: We found good stability on various aspects. On the southern half of the compass, the snow surface was moist or wet from warm temps, often isothermal through the whole snowpack. Expect a crust of varying thickness going into the weekend. Northerly aspects hold dry snow, a mix of softer sastrugi and wind-packed rounds on the surface. No notable persistent weak layers on the surface at the moment thanks to abusive winds and sun, and a generally a homogenous 4-finger snowpack from surface to ground on all but due north aspects. On a NNE aspect, we found the 11/6 facet layer lurking below 70 cm of slab, but it was discontinuous due to talus on the ground. It did not produce concerning pit results or signs of instabilities. We skied steep terrain on both north and east aspects with no instabilities.
