Pit #1: @10,400 due N @ 360* in a 20mx20m opening in the tight mature forest:
2 x ECTP (22 & 28) SC (informal, cleared off the top 25cm of F fluff b/c HS is 145cm) failed 25cm above the ground/120cm down on 4-5mm FC.
Slab is 4F & 1F+

Pit #2 5m away from pit #1: ECTX (presumably heavily influenced by the canopy & tree bombed out, as HS was 95cm and ~1.5m from 3 mature spruce arranged in a triangle
