Tip of the Iceberg?

This titanic iceberg  downed the Titanic

We always hear the figurative use of the phrase," Tip of the Iceberg".

Do we know exactly what is the tip and what of the rest of it?

This photo shows you the true massive size of an iceberg.

 From top to bottom, it is awesome!

This photo came from a rig manager for Global Marine Drilling in St. Johns, Newfoundland. Canada.

They actually have to divert the path of these things away from the oil rig by towing them with ships!

Anyway, in this particular case the water was calm and the sun was almost directly overhead.

So that the diver was able to get into the water and click this picture.

The estimated  weight of this iceberg is 300 million tons!
