Notes
From Obs: "Driving back from Grotto Falls trailhead, from the east side of the reservoir I could see this slide on the ridge that extends north from Blackmore above Blackmore lake. The slide was on a north-facing slope around 9,100', large enough to see with the naked eye and clear as day with binoculars. The crown looked multiple feet deep and either meandered, partially hidden from view, by another ridge or a substantial second avalanche a hundred feet away."
