Notes

From obs: "Toured up to the low angle meadows on the NE shoulder of Ross Peak. Dug a 8000ft and found no action in an extended column test but a significant result in a propagation saw test (PST END 20/100) at about 90 cm down. Some recent small avalanches in steep terrain along Brackett Creek that broke naturally within the storm snow from 1/3."

 

From obs: "Saw a small recent looking storm slab avalanche that appeared to be naturally triggered above the road on a south facing slope around 6000'.  It ran all the way across the slope ~30' wide and  ~4" deep within the recent snow.  The snow didn't move far enough to reach the road.  The slope was quite steep-- we didn't measure but I'd estimate 40*.

We also had localized cracking around our skis with planar breaks on that interface throughout the day, as well as a shooting crack when a member of our group jumped on a south facing test slope.  On our way back down we saw an even smaller (~10' across) avalanche on a SW facing creek bank that appeared to be triggered by another party as a test slope.  Both of these test slopes were steep and we had no results on two other, less steep slopes."
