There were no obvious signs of recent instability. Did have a very faint local collapse at about 1800’ on the skin track late in the afternoon.

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.
Weather

Wx in the morning was overcast with some breaks allowing for small windows of visibility. Winds were light most of the day with temps in high teens to lows twenties. By 2:30 clouds and fog had set in with vis literally 10’ all the way to about the 1000’ level. Had to get GAIA out to find the skin track.

Snow surface

Parking lot was a foot deep in unplowed snow. There was about 3 - 4 inches of new overnight snow on top of old skin tracks. Snow was still fairly light and loose at lower elevations but got progressively thicker and more consolidated/slab like with elevation but lacked a true wind crust.

Snowpack

1800’ 16 - 18” of storm and new snow over older faceted snow.
2600’ 22-24” of storm/ new snow over older faceted snow.

Numerous hand pits from 1800’-3000’ reacted similarly with moderate shear at the storm/facet interface.
