Secrets of the Lakes

摘要

The dented shipping container chained to the deck of the rusty barge could pass for an abandoned 18-wheeler, but for the fact that the barge is floating near the center of Lake Michigan. Inside the container, a half dozen faces crowd around a screen, where a blip tracks the location of a miniature submarine diving deep below the barge. The container is the sub's command center, and the blip is an unsatisfying image for the group packed inside, still sweating from the two days spent scrutinizing sonar tracks and blurry video images for the exact location of the sunken ore carrier Carl D. Bradley, resting on the floor of the lake 380 feet below.
