Snowpack

Instability Comment
<p>About 20-30cm new snow, soft-slab and loose. This snow has fallen on about a 1.5cm thick crust. New snow failed in an CT4 and ECTP4 on top of the upper most crust. Overall pretty right-side up snowpack, but there was a soft layer underneath the crust. No noticeable reaction below the crust on which the new snow sits. </p> <p>Ground layer is quite firm and damp. We measured about 85cm of total snow. </p> <p>This observation occurred at 8:45 pm. Slope was 30 degrees, outside air temp was low 20 degree. </p> <p>While the slab failed across the ECT, it was not bonded well and sloughed apart pulled. </p>
