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

COLD! -20F at the parking lot. Temps warmed with elevation and were around 0F at 3,000' or so.
Calm winds and clear skies.

Snow surface

Surface hoar was seen up to 2,000'. Did not note any at the higher elevations.
Wind effect was prevalent above 3,000' and especially along ridgelines. We found wind crusts (up to 4" thick) in exposed areas at the higher elevations. The last winds to hit this area were likely from Monday 1/13.
Areas out of the wind effect and most areas below 3,000' sported very soft faceted snow and good riding conditions.

Snowpack

We dug one pit at 3,000' on a W aspect. Snow depth was 145cm, around 5 feet.
No failures occurred in stability tests.
We did find the pack riddled with weak faceted snow. A problem for the future...
The New Year's Crust sits about 6-8" below the surface at elevations below 2,200-2,500'. This crust was degrading and very breakable.

Today's main avalanche concern were wind slabs sitting on faceted snow at the upper elevations.

Three to four glide cracks were seen in the headwall area just under the cliffs. See photo below of the largest one we found.
