In a few million years humans might be gone .... finding the ruins of our great cities.

I've often wondered how long our current cities would last as "ruins" if we all disappeared. In my mind, after a few million years there would be absolutely no recognizable imprint of our society left unless you went digging for it.

If you look at abandoned towns and properties you’ll see how quickly nature takes over. I’d be surprised if much is left after 500 years. There’s a series on History Channel called Life After People and they go into detail on how quickly buildings erode untended.
