Comments
Wind Loading from the NW Winds created this sensitive Wind Slab. While descending the E Ridge off of the the peak of Pt. Supreme, collapsing was experienced several times. Picture 1 is a small Naturally released pocket that was higher on the ridge line than the one that was remotely triggered (Picture 2 and 3). Time unknown for the Natural. Slide that was remotely triggered was triggered from 15 feet from the newly formed Cornice. Another Collapse and Whomping was experienced and then the slide released propagating up hill. Slide only ran 80 due to the transition/slope angle that lessened quickly.
