We dug a pit on a steep section of the drop in to stoop chutes, because we could see a lot of wind slabs in that area. Very Reactive wind slab and persistent slab beneath observed. We immediately carefully moved out of there and went for some less loaded trees. 3 Hand taps in, the wind slab let go at about 15cm deep. After 10 hand and 3 elbow, the slab below that let go at about 35cm. You can see pics at each release. The second slab left a very planar surface and looked like a faceted weak layer. We were quite concerned the wind slab would easily be triggered and step down to the persistent slab below.
