Cooke City, monitoring Feb. 3 dust/ facet layer
Date
Activity
Snowboarding
Recent snowpits attached from mid elevation E, and SE aspects near Cooke City.
Of note, it appears that the Feb. 3 dust layer, perhaps has become weaker/ more faceted with the recent below 0F temps of the last 4 days. Will continue to monitor this layer of concern as the weekend storm progresses.
