Avalanche Advisory
Advisory: Abajo Area Mountains Issued by Eric Trenbeath for Monday - December 12, 2016 - 7:26am
bottom line

Due to low snow cover, the avalanche danger is generally LOW in the Abajo Mountains. Be alert to areas of wind drifted snow at upper elevations along leeward ridge crests and terrain features. The snow pack is very shallow and weak at this time, and future snow loads will cause the danger to increase.




special announcement
current conditions

Snow cover in the Abajo Mountains is still quite thin and there isn't enough snow to recreate on beyond the road. There is only a few inches of snow on the ground at the trailheads and in the lower elevations.


Forest Service volunteer Chris Jacobson tops out at North Creek Pass. Pretty low snow up there.


On the backside near Robinson Pasture. Snow here was even thin on the road so we turned around.

description

There isn't currently enough snow to pose much of an avalanche danger, but be alert to wind drifted snow along leeward ridge crests and terrain features at upper elevations. Of note is the current snow pack structure. The weak shallow now is already deteriorating, and this doesn't bode well for future snow loads.


Chris Jacobson digs out weak, faceted grains, or "sugar snow" out from the bottom of the existing shallow snow pack. This makes an unstable base for future snow loads.
