Comments
this is a 2 for 1 report, saw two slides same dimension, aspect and elevation. Not sure I got the location right, is around the ivorys, just below the rocks/slab. There was a very similar slide below cardiac ridge.
There were multiple point releases, upper elevation, above 38 ish degrees in steepness, east facing Cardiff Fork. Pretty wind affected, west facing Cardiff, mid elevation exposed, had a stout crust/cardboard feel. east facing rode great.
For both slides I suspect that there was wind loading and the trigger was just the wind load or possibly one of the numerous point releases.
I think the interface was the new snow/old snow interface (surface facets) but this is just a guess as observation was from 1/4 mile away.
guessing they occurred during the wind event.
both sides did not break down deeper/uniform depth
