Thanks, thats better.... Nope no idea what to make of it. Was the Baltic ever dry? I mean they're was supposedly a time before the Atlantic sea flooded into the Mediterranean and apparently there appears to be sites of archaeological significance under water off the coast of Egypt etc.. Could the same be so for the Baltic, could that be some sunken building or foundation perhaps?

Interesting stuff, I'm going to do some research and if I turn up anything of interest I'll let you know.
