Update
This site lies within a protected area, and there are management / access issues. Having contacted the local authority and other bodies with a “nature conservation” interest, and having admitted to them that the precise position of the boulder has now been published, a couple of our respondents expressed regret about that, but admitted that they could not prevent members of the public from hunting for the boulder, and hoped that nobody would wish to damage it. But we are where we are, and must move on.
We have two samples from the boulder. We have been fortunate enough to receive sufficient financial support to pay for professional laboratory analyses, and the work is in hand. The results of the tests will be reported in a peer-reviewed journal in due course.
Quaternary studies colleagues who have been consulted about this find are both amazed and intrigued. They all confirm that it is the only known Irish Sea Glacier “giant erratic” on the South Wales coast, and they are fully aware of its significance.
Something is not right. This message is just to keep things from messing up down the road
