Huntrodd's memorial plaque. That link is to Don Burluraux's North York Moors Cam site, which I have mentioned before.
The visitor in blue is possibly pointing to one of the few coffin-shaped stone tombs on which are sculpted a skull and crossbones. As far as I'm aware, there is no reliable information about them. A former colleague used to send insistent tourists in that direction for Dracula's grave; he had grown weary of explaining that it was, after all, only a story.
A few first century visitors to another tomb, in another graveyard, were redirected with these words, "Why do you seek the living among the dead? He is not here, but has risen!" Luke 24. More than only a story according to Cædmon, Hilda and their successors.
