MONTEREY, Calif., Nov. 6 (UPI) -- A team of researchers with the U.S. Geological Survey and Monterey Bay Aquarium Research Institute were recently mapping fault lines near California's Monterey Bay when they came upon some sharp angles that seemed more ship-like than shifting tectonic plates.
When the geologists were done mapping the San Gregorio Fault, they sent a submersible -- a remotely operated vehicle known as Doc Ricketts -- to investigate further. Sure enough, their suspicions had been well founded.
