The anomaly -- for the moment, we'll call it that -- is approximately 2,000 feet below the surface of the water, measuring nearly 3 miles wide. What exactly is this thing?
Watch this video created by "Fade to Black" radio host Jimmy Church about the Malibu underwater anomaly.
"I needed him to find a way to get it under and above the water," Church said. "My first impression was that it was Greek, it looked artificial and didn't look natural.
"When you're looking at it from above, it's a nearly perfect oval shape," Church continued. "In the natural surroundings, nothing is symmetrical. Everything is eroded and covered in rocks and sloping and peaking, and right here, for 2 miles, it is a perfect oval with a black separation or outline to it.
"It just stands out that it has to be some type of roof. It's not unlike a domed stadium or a covered indoor race track or an Olympic arena -- it's got that feel to it. It looks like a perfect oval manmade structure sitting on a construction site."
