Red Flags
Red Flags: 
Poor Snowpack Structure
Red Flags Comments: 
Poor snowpack structure is a future red flag. On northerly aspects. I observed facets like I have in other areas in the Pahvants. See photo below. It still comes down to weather there is enough continuity in the current shallow snow pack (HST 0 to 6") to allow for a widespread avalanche. I think there is enough for a collapse but I am not sure about propagation and movement through all the brush and rocks. A very rough bed surface. If a big load of snow magically appeared, I would likely avoid the norths with facets for awhile.

Basal facets, 4 finger

 

 

Photo below:  this terrain is east facing, no old snow, this is an example that would be safe when we get snow.  Upper north facing aspects may be questionable.

In terms of hazard, none until it actually snows for real.

Variable weather on the ridge tops. Clouds socked back in after the 2nd photo.
