We recognised this pothole from Richard Allenby's site (see "more info" below), so we knocked the nettles aside and had a peer in to find...
...this wreckage, formerly to be seen just outside the pothole. It seems that someone has thoughtfully "tidied it up".
There is a much bigger pile of wreckage just above this location which certain others might pretend they had visited, but their photos didn't come out-in our case however the truth is that we were so focussed on finding this pothole that we just forgot.
