I am thinking of reaching such layers underneath coastal waters. How far out? Don't know.

hasn't ryan and pitman given us an idea by their discoveries inthe Black Sea? and if it is the same on the ocean coast wouldn't that distance make it almost impossible to excavate and explore?

my other question is, wouldn't being underwater all those years make it practically impossible to get an accurate reading on the date of the structures?

i will cite the japanese controversial 'monument' as an example so we can have something to go on.

here is a tidbit on what is happening withone discovery., not ancient but marine anyways:

This would seem to answer your earlier question about underwater dating.

Carbon testing of wood slivers shows they could date to the period when the Griffon was built, Vrana said at a news conference.
