The document discusses underwater discoveries made using Google Earth, where the author, Judy M. Johnson, notices various formations that appear man-made along the southeastern U.S. coastline and beyond, including unusual shapes and mounds near Cape Lookout, NC, and the Gulf of California. She speculates on the nature of these formations, suggesting they could be remnants of ancient structures or unexplained geological features. Johnson invites readers to share their own findings and provides links to related archaeological resources.
