Unintentionally triggered a small soft slab at the bottom of Pioneer main chute below a steep rocky section. It was slow moving and did not travel far. Measurements are an estimate, we did not go back to investigate. We suspect this was wind drifted snow that failed on top of a graupel layer from the 21st, as was listed as an avalanche problem for the day.
