The Blue Hole was caused by the roof of an underwater cave collapsing. The water surrounding the opening is relatively shallow, but the floor of the cave is over 400 feet deep. A typical dive starts by descending along the wall of the collapse to a depth of about 130 feet where you can then swim around the stalactites hanging from what was the ceiling of a once dry cave. The stalactites are huge, but relatively unimpressive, and the depth means you spend your time plastered to the ceiling. Gray rock with little natural light and no coral (not enough water movement) makes this a been-there-done-that dive in my book.
Bottom time goes fast as does your air at this depth, so back up past more boring rock until you reach the sandy bowl of the crater's bottom to finish your safety stop. If you go to Belize to go diving, you almost have to dive the Blue Hole, but if you're like me, it won't be on your "must do again" list.
A Blue hole can be found in Belize, the Bahamas, Guam, Australia.

A: yes because its 130 meters deep and the nitrogen narcosis can kill you the blue hole is located at off the coast of belize

Yes, there have been deaths, but not very often. They recently (December 2008) found the body of a diver on the bottom of Blue Hole. He had previously disappeared on a dive.
