This avalanche occured on north facing slopes near 9800ft outside the advisory area in the Absaroka Range. It was triggered as skiers jumped on the snow at the ridge top. They estimated depth to be 2-3 ft and the total width to be over 1000ft with a powder cloud that dusted the entire bowl. Fractures propagating over these long distances indicate the existence of a very sensitive weak layer stressed by recent snow and unstable conditions.
