Weather

Mid 20’s. 5/8 to 8/8 clouds calm wind

Snowpack

Cracking and collapsing was constant during our tour except for slopes that were bare prior to the most recent storm cycle. We picked a slope similar in aspect to the upper slopes of Mount Bellview and found a very cohesive storm slab covered by 11cm of fresh, light snow. The slab is resting upon a firm layer of old snow form October and Novemeber. This firm layer of old snow was covered in a weak layer of weak deformed grains (facets or hoar… hard to tell). This layer under the slab failed an extended column test at 22 taps.
