Might these be the ruins of the lost continent of Atlantis? Eager explorers certainly thought so, trumpeting this grid off the coast of Africa as streets in the mythical sunken city. Observers noted the area appeared to be the size of Wales, making such a large grid an impressive feat of ancient urban planning. The real explanation is far less fun: Google Earth engineers soon announced that the grid pattern was merely a digital artifact created by the sonar boats collecting mapping data. Whispers still linger, but it doesn't look like anyone will be dredging up a forgotten civilization anytime soon.
