Notes

From obs: "Probably already reported...but touchy storm slabs on Mt Blackmore. Attached is a photo of a natural from the approach, at the switchbacks to the upper basin."

From obs: Saw a fairly large (could bury a person) slide while heading up to ski on mt Blackmore. It was on a north aspect at around 8700 ft. It seemed to have failed in the recent storm snow, some wind may have made the slab a little thicker. The debris covered a portion of yesterday’s ski track. Higher in the bowl we found unstable snow around ridge lines, with several small loose sluffs coming down."
