- <p>On any steep slope, we could easily get very soft slabs to crack and run within the new snow. We also saw a few signs of natural avalanche activity within the storm snow on steep slopes. </p>
Our intended tour was up Bowman Fork to White Fir Pass. However, about a third of a mile on the Bowman Fork trail, we decided to turn around given we were easily triggering soft slab avalanches failing within the new snow. These avalanches were shallow (< 15 cms/6"), but the terrain we were traveling through had some steeper slopes above a narrow gully and we chose to not enter into this terrain trap.
South and west-facing slopes that are often brushy at these low elevations are smooth from a deep snowpack, and avalanches are running fast and far. Although we were familiar with this terrain, it was an easy choice to turn around given the sensitive storm snow and unusual conditions.

- <p>So much new snow in such a short period of time. The new snow was especially sensitive during periods of high precipitation intensity.</p>
Skin tracks were filling in with 10-15 cms of new snow within an hour.
