More detailed information about the avalanche: 

I counted seven seperate Cornice Fall avalanches in the Leavitt cirque. They were D1 in size & ran almost 900' within the new soft snow. No crowns observed. Not much evidence of avalanches from my ride today. Speaking with the locals they also found very few & small avalanches.
