Flat Holm Erratic Hunt (8): some interesting pebbles


Have a good look at these, folks.  Picked up on the beaches of Flat Holm by Linda, Sid, Chris and myself -- and all now being analysed by Sid and some of his colleagues.

Some of them look very interesting indeed, suggesting either W Pembs or Anglesey in the frame as possible provenances.  Click to enlarge.  Watch this space............

Where are Sid and his colleagues based? Have you been in contact with them long? I am hoping to find out more about a certain large exotic erratic which you, Brian, illustrated a while ago. It is on Bathampton Down's plateau, near the site of Bath University. The photo you showed was taken by Terence Meaden - I am trying to track him down for a Grid Reference.

Sid lives in Pembrokeshire, officially looking after geological matters in SW Wales -- but he also does some teaching in Cardiff, and maybe that's where he is at the moment...... some of his colleagues in Cardiff were, I think, going to give some help with identifications.

Mr H's comment is most interesting!

Two years ago I purchased the latest, newly published, BGS map of the geology of the Bath area. It appears that after decades of disbelief, the tide has turned,and they have at last accepted the interpretation, that the erratic gravel deposits on Bathampton Down were in fact Glacial deposits!

Where does that leave the naysayers?

BRIAN JOHN said...

I am constantly surprised by the accuracy of the latest geological maps -- there are some good surveyors out there, who know how to interpret their data, regardless of the pontifications that there may be in the literature.

Very pleased to hear that news about the latest BGS maps for Bath area, Alex. This confirms what Brian revealed recently in a Post which mentioned Bathampton area and also Kingdown near Box, to the NE - picked up glacial placename details from the map Brian illustrated. This was quite recent, either in November or September's Posts, from memory.

Alex, it is the August 19th Post, The Avon Ice Lobe. See the maps and the exchange of comments, as well as Brian's Post.

As Captain Jim Kirk told us, many aeons ago from Enterprise, the Truth is Out There.......but not as we know it![or have been misled to believe it, since the 1920's in the case of Stonehenge Blue Stones and their method of transportation in a SW direction].

Thanks Brian, submitted an extra Comment whilst you were replying to my earlier one this evening. Would like the Ancient Landscapes Project folk at Bradford - on - Avon (archaeologist Roy Canham and Geologist Richard Clark in particular) to keep an eagle eye out for glacial features during their research of the plateau landscape north of Bradford and east of the river Avon.But rhe research is primarily to do with revealing human alterations to the landscape from prehistoric times.

For "Geologist Richard..." read "Roger" in previous comment.

Bradford - on Avon Museum website is:-
