Comments
There was another big slide just North of Castle Rock. It looks like it was triggered by a cornice fall but it released a slab approximately 300 feet wide and ran 600 vertical. The slab looked like it failed on the dirty layer from the storm a couple of weeks ago. There were not large chunks of cornice in the debris like on the Cornice Ridge slide. I am guessing the cornice fall was not as large as the Cornice Ridge slide. The alpha angle on this slide was 22 degrees.
