A "loving lake monster" in the shape of a dinosaur is floating on East Canyon Reservoir this week in a campaign to promote peace and prevent extinction, its creator says.

Vincent Coon, 26, Salt Lake City, said his submarine in the shape of a plesiosaur is on a floating peace mission of sorts."At a certain time, I was going to broadcast a message by a public address system. . . (that) in a loving way, will remind people" to prevent the earth from becoming extinct as did dinosaurs, Coon said Wednesday.

"The truth is, that your gravest problems can never be completely healed by military, political, or technological antidotes," said a statement explaining the dinosaur's existence.

"Cosmetic answers," such as found using political or military might, are not the way to solve the world's problems, Coon said.

"People have to freely choose from within . . . to bring about the kind of changes in order to solve some of those problems," he said. "This whole project was centered around . . . a cute, loving message of getting that out."

Aside from the message of brotherly love, Coon said the submarine is a test of physics and mathematical theories. Some problems were encountered Wednesday as the monstrosity had some balancing and mooring difficulties.

But the problems are miniscule, compared with the enjoyment Coon hopes his creation will bring.

"We had no idea this was going to be the year of the dinosaur. I originally built it to get a message across," he said, adding, "I had a number of kids here just delighted to see it."

Coon said the inspiration for the submarine/dinosaur was was born when his father read him "20,000 Leagues Under the Sea." "And I guess that influenced me ever since."

"Ever since they (the children) were small, he has always loved dinosaurs," said mother Jeannine Coons. "This little son built a submarine when he was 9. And he seems to love levitation devices because this is what that is."

The family members, all of whom participated in the project, helped design the floating billboard, which the family also wants to use to teach children.

"We turned him into a more loving lake monster than that of Loch Ness," said Coon, who hopes to attend Brigham Young University to study physics and math.

The floating dinosaur weighs two tons, is 8 meters long and can dive about 30 feet.
