Comments
Partner traversed under a cliff band and triggered this slide. Ran to the trees with a bit of force. A bit unexpected as another party had skied and sluffed out just skiers right of the slide. Didn't have a chance to see what it failed on. Could have been graupel below the cliff, could have been a density change in the new snow. Possibly wind loaded, but we were well below any summit.
