Burnt Knob

The buried melt freeze crusts, now down 120 & 135cm at this location, are characterized by stiff to very stiff snow above & below (1F-P), and the layer itself (5-10mm thick) is very weak (F-4F). The crystals continue to decompose, however they are not mixing a significant amount with the surrounding layers, ie the layer is still very apparent in the snowpack, and can be seen clearly on the pit wall. There was no reactivity to compression or shovel shear tests on this layer. At the base of the storm snow (since last Tues, aprox 50cm down), there was moderate clean (SP) reactivity on top of a windslab. The snow above this layer is very low density (F), and had no signs of slab characteristics. Considering the deeper weak layers, even with the lack of reactivity to snowpack tests, I have low confidence in the snowpack here, and see a clear low probability high consequence issue to consider.

Numerous sloughs to size 1 from steep, rocky terrain. No reactivity to skier traffic in steeper pitches.
