"Today while touring in the Deer Creek drainage in the Northern Madisons my partners and I noticed many red flags. Wind was strong from the WSW. We had lots of collapsing and some cracking while touring up. We bailed on our main objective, and while returning to the car we triggered a wind slab remotely from the bottom flats of a gulley. A rider in our group began to descend when we felt and heard a large whumph, followed by a 3-5 second loud rumbling before a wind slab on the ridge above (100 yards away) released (SS-ARr-R1-D1-S, NE aspect @ 6700'). It was about 50' wide and 1-2' deep, but didn't have enough energy to run far down the slope. Touchy stuff!"
