[Peter Lindberg, Treasure Hunter]:
“We have experienced things that I really couldn’t imagine and I have been the team's biggest skeptic regarding these different kind of theories. I was kind of prepared just to find a stone or cliff or outcrop or pile of mud but it was nothing like that, so for me it has been a missing experience I must say.”

I remember a few years back i seen on on CBS news site that scientists tracked on sonar a large moving object in the pacific ocean they estimated the object was at least 2 miles in diameter and moving at very fast speeds deep under the pacific ocean, they never figured out what it was it was too fast to be a large school of fish was not temperature currents as they can show up as large blobs on sonar, to large to be anything made by man and to deep to send in a team of experts to go and investigate. They tracked it for a few days then it disappeared.
