Whumpfing, but stable pit results in Beehive Basin

Performed two ECTs and a PST on an E aspect at roughly 9000’. HS was about 50 cm and the old faceted snow below the new snow was obvious. We had two ECTX in adjacent pits and a PST result of 40/100 Arr on the interface of old and new snow. These results were surprising as the snowpack structure had 4/5 lemons and we experienced Whumpfing on the same slope just 100 feet away. We also experienced whumpfs in other locations throughout the basin.
