Weather Comments
Cold, staying in the single digits at the upper elevations all day. But sun and no wind conteracted the temps and made for a pleasant day.

Snow Characteristics Comments

Some settlement, snow staying dry and light.  Right side up storm. Great turning conditions at high elevation down to mid though the new snow height decreases rapidly as you go down in elevation.

Poor Snowpack Structure
Red Flags Comments
Still a bit of a facet/crust sandwich under the most recent storm snow. Suspect structure reinforces travel advice to stay on lower angle slopes NW through E at high and mid elevations.
Avalanche Problem #1
Persistent Slab
Problem #1 Comments

Overall snowpack, still considered on the thin side, contains multiple weak faceted layers. Not quite enough water from this last storm to reactivate but will keep in mind if we get another storm with high water content or rain. 

Snow Profile
Slope Angle

Similar layering was found for another 800'+ vertical as we moved downhill.  The facets at 80 cm (beneath the uppermost crust) is the layer of most concern.  The storm didn't seem to have enough weight to create avalanching on this layer, but it still a bit "spooky".  Some very localized collapsing just beneath our skis. 

Below, another pit on almost due north, at 7,900'.  Upper crust was variable very over short distances, but facet layer uniform across the slope.  Again, some small surface hoar mixed in. Not much of a load from the last storm, but concerns with future loading will mostly be in the upper weak layers.

Nice to see the Ogden area mountains look a little more winter-like. Not overly hopeful for low elevation TH's to fill in as we move closer to March.
