Observer Comments

No signs of instability, save for some very shallow surface sluffing in the top 2-3" of new snow from Feb 6th (yesterday). Photos, show the shallow sluffs.

We also saw some small slabs that we are unsure if they were older or released during the new 3" of snow and wind on Feb 6th. They are across the Seattle Ck drainage to the North of Big Chief.

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

Sunny with valley fog to 1,500'. Light to gusty winds along ridgetops in the 10mph range. Temperatures in the mid 20's F.

Snow surface

2-3" of new light snow from Feb 6th. Slight wind affect along Seattle Ridge.

Snowpack

We found between 5-20" of loose snow over various crusts along Seattle Ridge and into the headwall zone on the steeper slopes. We dug in where the Jan 21 buried surface hoar had appeared to already have slid and therefore found only loose snow over facets and crusts. No slabs seen, but we were watching for them.. Stayed in shady terrain.
