What he proposed to Hibbet was breathtaking in its imagination and scope, yet remarkably simple. His plan was to use watered-down versions of the Kovacs electromagnetic waves to detect anomalies below the ocean floor that were suspected of causing surface disturbances. Every oceangoing vessel of a certain size would be outfitted with a Kovacs sensor mounted on the prow. The sensors would constantly broadcast information, which would be compiled with satellite observations and global electromagnetic field readings.

The data were fed into computers, analyzed and rebroadcast as warnings of breeding areas for giant waves. Ships could then chart courses around dangerous breeder areas. It was decided to conduct sea tests in the vicinity of the giant waves that had sunk the Southern Belle. Because of its interest in ocean eddies, NOAA was asked to participate, which got the Trouts involved.

The two ships rendezvoused over the site of the sunken Southern Belle. A wreath was dropped into the water in remembrance of the ship's crew. Then the field tests began over a period of several days. The tests uncovered several glitches, which were quickly remedied. Now, with the system an obvious success, the mood in the control room had become downright raucous—especially after it had been lubricated with generous shots of tequila.

At one point, an ebullient and slightly inebriated Al Hibbet turned to Zavala and said, “It's a shame Kurt can't be here. He's missing all the fun.”

Zavala smiled knowingly. “I'm sure he's doing fine.”

KARLA JANOS came out of the tunnel blinking like a mole. Her face was dirty, and her one-piece jump suit was covered with dust. She shook her head in wonder, still impressed by the scene that confronted her eyes. A temporary village had sprung up on the grassy bowl at the bottom of the caldera. At least two dozen large tents housing facilities for sleeping, cooking and research were laid out in neat rows. Several helicopters were parked nearby.

The area around the tents bustled with activity. Access to the crystal city had been improved by drilling a tunnel and clearing away the rocky debris that was in the way. Cables snaked into the tunnel from gas-powered electrical generators. A steady stream of scientists and assistants was moving in and out of the city.

Karla was elated and exhausted at the same time. The scientific crews had been working twenty-four hours a day on three shifts. Some, like Karla, had become so involved in their work that they had worked more than one shift. She tilted her chin back and gulped several breaths of fresh air. In the blue-gray light, she saw a speck come into view over the rim and begin a descent into the valley.

As the object neared, she could see that it was a large, colorful canopy with a human dangling below. It couldn't be. Hoping against hope, she walked away from the tents to a clear area and madly waved her baseball cap in the air.
