It is an easy mistake...one I often make..

In regard to the two stones, I will try to get back up and have a closer look..need to find an entrance into the field first. They are not marked as anything but your right they do line up nicely. Behind where I took the photo is a gorse and rock covered tor not even give a name on the map..but it lines up as well.....

watch this space as they say.
