Avalanche off Bridger Peak

 Slide triggered from above (ridge line) onto east facing slide path on Bridger Ridge. Knocked off microwave-sized cornice while skinning which fell and triggered the slope below. We had zero intention of skiing that slope or any like it on todays tour. Slide seemed to start very slowly and then propagated North (to the left in the pictures) before running down the slide path. Looking at the slope no parties or individuals were present around us or in the run out to the best of our observations. Not surprised by the instability at play and yet another reason to heed to the forecast.
