Metal dome windslab

We had skiied two adjacent slopes working into this feature. Was thinking windslab had tightened from overnight cold and clear weather. Worked into steep start zone(steep convex roll on half of entrance) and ski cut size 1. Ran far and very fast. Debris had settled in 5 seconds after triggering. 10-60cm crown running fast and easy on December facets/crust combo. 10cm burried windslab (4F-1F) under 40cm unconsolidated snow. Current loading from the west. Propagation limited to the steep unsupported feature. Kept it mellow for the rest of the day and had a great time. Sorry for no picture.
