Around 9:30 AM I dropped in to the skiers right side of the south face of mount superior. On my second turn on a bank I triggered I soft slab that broke above and below me about 80 feet each way. I chose to outrun it and once I had my distance pulled off on to a higher point and let it pass by. It flowed down the steep chute and stopped in the middle apron. Although it was late to be dropping into a south face in powder for this time of year the clouds had kept the sun at bay all morning and warming wasn't an issue until you got to the apron. My guess is that the new snow that had been heavily fall earlier that morning was still very sensitive and pulled down into a soft slab. Winds were light
