Storm slabs on the knolls

Set off a few small size 1 slides on the steeper pitches of the knolls, all skier triggered. Storm slab failing on the convex rollovers and only running to the mellower more supported pitch below. Slow in speed but very chunky. Biggest had a run length of 40m, might have been size 1.5? Most only ram 20m or less. Crowns of 30 to 40cm.
