Observer Comments

The avalanche reported here was soft and unconsolidated snow. However, on a higher and more exposed ridgeline, the snow had more of a wind slab character with 20' radius shooting cracks and audible collapses.

There were also dry snow avalanches present in steep terrain over all aspects.

Weather

Weather

30 cm of moderate density new snow at all elevations. Intermittent light breeze.

Snow Characteristics

Snow surface

New storm snow.

Snowpack

Moderate density (surprisingly heavy) new snow on top of surface facets on top of the strong base. We did not dig a pit or perform formal stability tests. However, the instability at the new snow interface was obvious both from observations of natural slides and switchback cuts, pole probing, etc.
