Submerged forests map (update)



The map has been updated, through the addition of Pendine (see the recent post) and Broad Haven.  On a recent Facebook group page, there were confirmations from Anne Rogers and Mary Butcher that they have both seen the submerged forest -- including tree stumps -- on the beach at Broad Haven.  Unfortunately, neither of them has photographs.......

I have also added more "candidate sites" since I am convinced that almost ALL of the sandy embayments around the coast will have peat beds and tree relics under the sand -- ready to be exposed by the "right" combinations of winter storms, tidal scour and wave height and wind direction factors.  There will also be submerged forest relics in abundance within the Milford Haven waterway -- but here of course storm wave conditions capable of "stripping out" sediment in vast quantities are hardly ever seen.

Postscript (7th June 2020)
Thanks to Charles Mathieson for digging up a reference for St Brides.  Apparently in Lewis's Topographical Dictionary of Wales, dated 1833, there is a reference to tree stumps being exposed on the foreshore during an extreme low tide event.   I will alter the definitive map accordingly.........
