Which controls did you think were on unmapped rocks? I had a few wobbles in the circles but put it down to myself.
112 (also description said 1.5m, but it was about 1m, so not even something you'd look at), 95 (i think it was on one of the rocky ground dots to the NE), and 87 seemed to be on something too small to be mapped given the size of the other stuff in the area.
