I watched a show on Science Channel or H2 or NatGeo...where they were looking for and finding remains of communities in what is now the English Channel. One guy was obviously a boat builder and the pieces of wood found there were dated to, Im going to say,b 12000-14000BP.
cool stuff.
Maybe it’s the Isle of Wight one, here’s a list of related links, anyway. :’)
