Comments
appears to be snowmobile triggered, either remote from their high marking to lookers left of slide or triggered from cornice break above.
happened around 10am, some in our party heard it.
failed on surface facets and broke to the ground. There was far too much hang fire for us to search the area and we did not witness the slide. But i did report to utah avy and getting this report in asap.
