Actually saw four different distinct slides in West Monitor, they were all between 60 to 100ft wide about a foot deep and triggered by cornice falls. They were all wind slabs that ran on the old hard bed surface from before this weeks storms. They all ran to the flats, but the slide on the more E-SE facing ran the farthest, a good ways out onto the flats, thinking it ran further because the bed surface was a ice sheet and the slope was around 38 degrees in steepness. We think they all ran around the same time this morning when the PI rates were high after the front, and during the period when the wind spiked. Photos, Pics were tough to get but got a few of, two of the slides, when you put them all together they pretty much took out 80 percent of the bowl.
