Red Flags
Red Flags: 
Wind Loading
Poor Snowpack Structure
Red Flags Comments: 
wind was blowing at times, i would imigne that loading is occuring at the upper elevations which were obscured today. Facets were not as bad as I was expecting in this area, I would expect them to heal at some point. However ECTS's are propogating (see below).
Avalanche Problem #1
Type: 
Persistent Slab
Trend: 
Same
Problem #1 Comments: 

I think the 2 finger snow sitting on top of 2 facet layers is of concern. Moderate with perhaps pockets of considerable in areas traveled today, could easily be considerable in the high elevation starting zones.

Avalanche Problem #2
Type: 
Normal Caution
Trend: 
Same
Problem #2 Comments: 

Normal caution for early season travel, however the snow pack in the Pavants is impressive!

Photo Below , Typical Pavant Slidepath.......North facing mid Maple Canyon.

Photo below, not your typical Wasatch Exit......

 

ATV's not making it very far past the trailhead.  Still able to drive to the 6400' trailhead.  Snowpack is consolidated but the ATV trial I skinned up today is likely not ready for a sled yet.

 

Hazrad of Considerable is based on the upper elevation start zones.  Moderate elsewhere.
