Congratulations and serious respects to the intrepid volunteers of the Durham and Northumberland rock art project. Cheers to Rockandy for posting the pics and notes here on tma.
Finding previously unrecorded spirals carvings is a thing worthy of note in itself, even more so to have found them on a vertical surface.
But finding them on the vertical surface of an inaccessible cliff above a river, whilst bobbing about in a dinghy? Hey-mon! That is dedicated rockarteering!
