"When Denmark's raven soared high,
Triumphant through Northumbrian sky,
Till, hovering near, her fatal croak
Bade Reged's Britons dread the yoke;
and the broad shadow of her wing
Blackened each cateract and spring,
Where Tees in tumult leaves his source,
Thundering o'er Caldron and High Force;
Beneath the shadow the Northmen came,
Fixed on each vale a runic name,
Reared high their altar's rugged stone,
And gave their Gods the land they won.
Then Balder, one beak garth was thine,
And one sweet brooklet's silver line;
And Woden's croft did little gain
From the stern father of the slain."
Following recent discoveries I have made on the North Yorkshire Moors and information I have received from Graeme Chappell, I think these marks are not prehistoric cups but marks left by bullets. Apparently standing stones were used for target practice during World War 2. Further evidence for this on this particular stone is that the 'cup' has damaged the carving of the date which would imply that the cup is younger than the date carving. The close proximety of an army training ground would also support this.
