    The submerged prehistoric forests at Trusthorpe and Cleethorpes, Lincolnshire — new post by me :) http://www.caitlingreen.org/2018/08/drowned-forest-trusthorpe.html …pic.twitter.com/4zDnKMselb

        Due to beach replenishment & erosion, the prehistoric submerged forest at Trusthorpe is now rarely seen, but was visible on Monday this week due to a very low tide; although only two tree stumps were finally exposed, more could be felt just beneath the water a little out to sea…pic.twitter.com/Kk8ZiOj2Dm

        In previous years, such exceptionally low tides have revealed far more of the submerged prehistoric forest at Mablethorpe/Trusthorpe, as can be seen in these pictures from 1984, and beach replenishment at least partly to blame, burying the trees in sand: https://www.flickr.com/photos/29450962@N08/5008789677/in/photostream/ …pic.twitter.com/u8X7P7N3IO

        Beach replenishment isn't the whole story, however—it also seems that the prehistoric submerged forest has been subject to significant erosion since the 18th century, when low tides on the Lincolnshire coast would reveal sections a mile wide! Down to 150 yards wide by the 1920s…pic.twitter.com/9PVfyLiOAP

        The submerged prehistoric forest on Cleethorpes beach is a little later in date—probably belonging to the Late Neolithic—and rather more of it can currently be seen...pic.twitter.com/cTs1NYeZVe

        That forest reminds me of talk of Doggerland. Do you have an opinion on the theory that a substantial landmass linked Britain to north sea coasts of the continent at a time of human habitation?

        Oh, yes, definitely correct — have solid evidence for it and good reconstructions both of its changing coastline and it's landscape! :)

        Thanks for responding. It's so hard to fathom, like a another variant of the Atlantis myth. The idea that it is not some "ancient astronauts" fiction is really stunning.

        The large trunk in the right-side photo bears evidence of ancient beaver activity. Could it be?!

        So, how would you tell the difference between Beavers and, say, stone axes ?

        It would be very difficult, after centuries of erosion by salt water, tides and currents. The marks left by little beaver teeth (or axes) would probably have been erased. But enough of this! Caitlin is a serious academic with little time for this nonsense from fellows like us!

        Apologies if this seems trivial, but I was just adjusting sea levels in a random-generation program called Wilbur as I glanced past this post :) As a non-academic person I really do appreciate the blog posts you share about landmass change. Thank you!pic.twitter.com/Hq4cGCWE4n

        What a coincidence! I suspect it must have been rather alarming for anyone living through the faster periods of change, like c.6,200 BC!
