Observations

- The GSG A1 tour today had a very full value day out in the field. We observed the notable natural wind slab avalanche other parties reported on the NE repeater slope near top of pano dome and also verified that we indeed we have a slab over facets within our snowpack. The distribution and variability of this slab over weak layer still our largest question mark.

- Notable test results: CTH (SC) down 80cm on 4F facets + ECTP25 down 80cm on 4F facets (this layer of concern is clearly visible in picture of snow profile within this ob)

Signs of Unstable Snow

None reported
