Red Flags Comment
<p>A day of red flags. They were everywhere from the recent snow, the strong winds blowing snow, the facets in our snowpit, 2 avalanches observed, and a collapse on a south aspect at 9,350'.</p>

As elsewhere in the Wasatch, the cornices on the ridgelines are getting huge (see photo).

We traveled on both north and south aspects today. We dug our snowpit on a north aspect. We had lots of red flags, but conditions seemed more stable than we were expecting.

Snowpack

Instability Comment
<p>We saw 2 large cornice breaks. One on a north and one on a south aspect.</p> <p>I selected PWL as the second problem, but it could easily be new snow. I didn't select new snow since the snow seemed to be bonded well to the old snow. The facet layer under the crust (see snow profile) was very pronounced, but I the area we dug, we did not get propagation in our extended column test (ECT). This layer is getting close to a meter deep which will hopefully help reduce the risk of this layer.</p>

7-8" of new snow overnight. You could feel the upside-down snow from the Thursday storm under the new snow.
