Thanks for the replies, I too am attemting to avoid work, but my plan has been gradually unfolding all day.

I'm pretty sure he wasn't referring to Mitchells Fold, he seemed to be saying there was evidence actually on the Wrekin itself.

I wasn't aware there was a Cairn located nearby...I will have to do some more digging (no pun intended.....).

Hope your work avoidance strategy proves more sucessful than mine!
