Here's a story about the structures found off the coast of Cuba. It was first discovered last May 2001 but the story didn't reach the national news until six months later.

"a huge land plateau with clear images of what appears to be manmade large-size architectural designs partly covered by sand. From above, the shapes resemble pyramids, roads and buildings." - Paulina Zelitsky, ocean engineer, Advanced Digital Communications, May 2001

Now some scientist are saying these are natural formations. I myself see this as indications of a planet that goes through extreme geological changes on occasion.
What do you think of the photos, natural or sunken city?

BTW there should be a science board here!
