Red Flags Comment
<p>Very high uncertainty with the onset of this storm and the fact that it was continuing to snow and blow. We made the decision to avoid all terrain steeper than 30 degrees, we stuck to our plan and had great skiing conditions. </p>

We rated this pit as a GCS of 8. Structure (3) Propagation (3) Structure (2)

Snowpack

Instability Comment
<p>Winds picked up above 10,000'. We noted previous wind loading and sensitive cornices along the ridgelines.We saw smooth rounded deposits of new south on northwest- east facing aspects.</p> <p>With 24 inches of new snow and 3.5 inches of water we had concerns over how the snowpack from earlier in the week would handle all this new weight. The storm started with graupel and there was uncertainty with how the graupel would react. Results in our snowpit showed that the graupel played well with the other layers. </p>

This was the type of storm that keeps people in Utah for the rest of their lives. Right side up storm with decreasing densities throughout the event.
