Stu and I came across this stone whilst hunting down the lost stones of the Shap Avenues.
Stu's GPS puts it at NY 55821529
The cup mark is of a similar dimension to the carvings on the nearby Asper's Field stone and the Goggleby Stone - 12 X 12 cm with possible peck marks visible.
From the looks of the staining on this stone it appears that the carving has previously been buried in the soil/vegetation and has therefore been overlooked.
It begs the question, how many other marked stones are there laying around in the fields surrounding Shap?
