Natural avalanche date unknown, but the best guess would have had it occurring early in the storm event on Saturday 1/20/18 while the winds were still more out of the WSW to W (before they turned NW). Debris was totally buried with what appeared to be most of the event. It appeared that the slide was triggered by strong winds as this chute is a mid slope feature. The winds appeared to be loading out of the WSW. This is very rocky chute with cliff type rollover entrance and rocky sidewalls. It fits the pattern/definition of the isolated Persistent Slab possibilities still lurking out there. Photo not great due to moderate PI at the time of observation. Highlighted lines indicate visible crown despite photos limitations.
