Red Flags Comments
Cracking around the skis began in earnest at 7000'...and localized collapsing began soon thereafter. POOR snowpack structure with very weak facets and occasional SH from the trailhead to the ridgeline. Generally lacking a well-connected slab in most areas.

Problem #1 Comments
PWL present from Lambs trailhead to the Mt Aire Ridgeline. Generally lacking a well connected slab. While c/c was noted very early on, they were very localized. We saw no natural or human triggered avalanches on our tour.
Grom score for the profile was a 1 and a 3.
I currently picture avalanches to be localized to areas with recent deposits of wind drifted snow in exposed terrain. The danger will spike very rapidly with the next storm of any wind and water weight.
