Some climbed up the hillside laden with empty buckets, while others staggered down under their loads. On a level section three-quarters of the way up the hill, shovelers filled the buckets with mud. They moved like automatons, as if their bodies could no longer perform any other act but scoop and dump. Farther up the hillside, others manned water cannons. The cannons were fed by hoses that snaked across the landscape to where glacial runoff from the distant mountains had been diverted into an earthen retention pond. Gravity forced the water through the lines so when it exploded from the cannons it was an arcing jet that the workers cut back and forth across a dirt embankment, sluicing away layers of soil with every pass.

Excess water from the guns poured down the hillside, gathering the topsoil until it was a liquid slurry as treacherous as quicksand. In those first moments that Eddie watched, dumbstruck by what he was seeing, a thick wave of mud suddenly shot down the slope. Those not quick enough were caught in the swell and tumbled down the hill. Some rose quickly back to their feet. Some more slowly. And one not at all. He was soon buried alive.

No one paused from their labor.

Strung over the workings on wooden poles were acres of camouflage netting that had been dyed in the same hues of gray and black and brown as the landscape, so from above, the site was completely hidden.

Near the beach where Eddie and his group gaped, haunted-eyed workers dumped their buckets into a series of mechanical sluice boxes, devices little changed from their introduction more than a century ago. The mud was washed down a long table by a gentle rocking motion. The bottom of the trough was lined with baffles that would trap and separate the heavy material from the lighter overburden. The waste fell away at the end of the boxes and eventually reached the ocean, where it spread in a brown stain, while the concentrated ore would need to be scraped away and taken for further refining.

A bucket brigade of workers formed a human chain from the tables to a three-story building a short way down the beach. Like the undulations of some enormous worm, buckets of ore that had been cleaned out of the sluice boxes were passed hand-to-hand toward the building. Eddie saw that what he assumed was the processing plant had been bolted down to a flat, oceangoing barge that could be easily towed away from the site. Tendrils of white smoke rose from a short stack next to the structure, telling him that whatever process they used to get their final product required heat.
