I don't know too much about this sort of thing, and that's why I started this thread. I'm hoping someone who knows about this will be able to help.

From what I know, the continental shelves are submerged during interglacial periods. But I really can't help but wonder if there are any ruins of ancient civilizations on at least one of the shelves.

Not just that, but I spend alot of time in Google Earth. There are areas where there are islands, and around those islands is a shelf as well. And the ocean is only (on average) about 3,000 feet deep in these parts.

Some parts it's only a few HUNDRED feet deep.

If I'm not mistaken, the Ice Age ended about 9500 BCE. It started 100,000 years before that, but there were indeed (primitive) humans around at that time.

Here are some pics from Google Earth:

What got me interested in the first place:



NW of Madagascar. Notice how it raises (or drops) abruptly. This whole shelf fragment (where there is no land, of course) is 250 feet deep on average - the whole thing. These static pictures don't do any justice, however. The closer you zoom in, you can really see what I'm talking about:



East of Madagascar. The top-most part varies from 3,000 feet to less than 500 feet deep:



Australia South, and Thailand NW: Looks like it could have been connected at one point. But what is under that water?



Near Antarctica:



The Bering Strait, area. Looks like alot was uncovered back then.



I really wonder what could be down there...

I encourage you to go to Google Earth yourselves and check out these areas.

Hey guys.

Now, the reason why I am still posting as opposed to going to the other threads is because I feel what my OP is addressing is slightly different. Slightly. If I'm wrong, let me know!

Anyway, it's also looking like the area when the UK, Sweden, Finland, The North Sea, etc. may have connected to Greenland, and Greenland may have connected to Canada. Interesting in my eyes.

Check it out:

Obviously you know what you're looking at. UK at the bottom left, and Sweden and Finland towards the middle. Obviously the North Sea wasn't a sea at that point and connected these landmasses to each other and to Europe:



Next up! We have a more North Westerly view. North of Finland looks especially interesting. Not just that, but like I said it looks like Greenland may have connected (South-Western part of Greenland:



I don't even think I need to explain the next picture. You do the math:



And finally, a pic where I tried to get it all:



How many things haven't we found yet? I am so intrigued. Unfortunately, the sea elements probably broke everything down. Maybe not.

Damn!

And Texas dude: I didn't purposely steal your thunder. I missed all of those other threads and I came up with this on my own, thanks to Google Earth.

If I did steal it, it was totally 100% inadvertent.

Edit to add: The pics are offset by a little. They are not showing up in the thread at their full size, so please try to "offset the offset" if you get my drift!

You know where to find the full pics - in my profile or somewhere in there.
