Fitz, I’m sure you will appreciate this little titbit with regard to your enthusiasm for this area. It’s not like I’m saying it’s a definite prehistoric find of course. But it echoes similar things at least:
In digging peats near the east end of Sunbiggin-tarn, about 1730, two pair of bulls horns, jumped together in the posture of fighting, were found, and one pair of them was to be seen at Howgill Castle in 1777.*
The east side would be that nearest the cairn. And of course you’ve got ‘Cow Dub’ to the south (pool / black cow?) – another bovine connection. Well to be honest they could be any horns. But they must have been impressive to be taken to the castle. I was thinking ‘how do horns survive in (acidic) peat?’ but actually bog bodies have demineralised bones and Lindow Man has got lovely fingernails. So they could be old.
