Observed several wind pockets that released near ridge lines in the Turnagain motorized area. Picture one is on the knob that divides Main bowl from Juniors bowl; trigger unknown but likely remotely triggered or natural. Picture two is a west/northwest aspect of widow maker, likely snow machine triggered but unknown. The last picture is of the same west/northwest aspect of the widow maker/juniors bowl knob but after we rode to the ridge and skied down to lookers right of the photo. We all felt a collapse on the ridge and I believe that we remotely triggered that small pocket that was not seen when we took the first photo 20 minutes earlier.
