The cause of death has been determined for the 29 year-old Jackson man who was killed Thursday afternoon in an avalanche south of Jackson Hole Mountain Resort near Cody Peak. Teton County Coroner Kiley Campbell says Michael Kazanjy died as the result of asphyxia when he was buried in the avalanche debis at the bottom of Pucker Face Bowl. However, Campbell explains that it was the pressure of the snow around him that cut off his blood supply and prevented the oxygen from being distributed through his body rather than being suffocated. Michael Kazanjy was reportedly skiing out-of-bounds in the Pucker Face Bowl below Cody Peak with five friends when the avalanche triggered, catching Kazanjy, carrying him the full length of the slide and burying him at the bottom. He was quickly unburied, but efforts to revive him on the scene were unsuccessful.
