Notes
The avalanche on the south face of Mt Abundance was set off at about 2:00 pm on Thursday. A rider realized he triggered a slide on his way back down the slope. It was estimated to be at least 1+ foot deep, 100 feet wide, and ran 100 feet slope distance. It was big enough to bury a person.
This depth (est. 1+') is similar to the faceted layer that was unstable near Lulu Pass the day before (ECTP22).
