I went up Eyam moor today to check out a posting on the Portal of a cairn up there having a chunk taken out of it. See latest images for Wet Withins. I'm pretty sure its done by a human hand.
Thing is that cairn isn't listed on here and I'm not sure its on the SMR. That and a large pit next to it, and its weird almost conical shape makes me think its a small relatively modern slag heap.
Anyone on here know?
