THE ZODIAC POUNDED OVER THE CHOPPY SWELLS, careening off small chunks of ice as a freezing mist sprayed into the air. The pi lot kept the throttle open until approaching a wide expanse of unbroken ice that stretched from the shoreline. Finding a section with a sloping front edge, he drove the inflatable boat up and onto the sea ice. The hardened hull of the Zodiac slid several feet before mashing to a halt against a low knoll. Seated near the stern, Zak waited for the geology team to exit the boat before he stepped out, following a guard carryi ng a hunting rifle whose sole job was to ward off any inquisitive bears.

“Pick us up a mile down the coast in exactly two hours,” Zak ordered the pilot, waving an arm to the west. Then he helped shove the Zodiac back into the water and watched as the rubber boat sped to the Otok, idling a half mile away.

Zak could have stayed in the warmth of his cabin, reading a biography of Wild Bill Hickok that he had brought along, but he feared the geologists would dawdle in the cold. What actually drove him ashore, he didn’t want to admit, was the disappointment he felt with their geological assessment of the Mid-America mining camp.

While it was hardly a surprise when they confirmed the rich ground content of zinc and iron on the south side of the island, he had expected that some trace elements of ruthenium might be present. But none were found. The geologists in fact found no evidence of any platinum-related elements in the exposed stratum.

It meant nothing, he assured himself, since he knew exactly where the ruthenium would be found. Digging into the pocket of his parka, he pulled out the journal pages that he had stolen from the Miners Co-op. In heavy charcoal was a hand-drawn circular diagram that clearly resembled West Island. A small X was marked on the northern shore of the island. At the top of the page, a different hand had written “Royal Geographical Society Islands” with a quill pen in a Victorian script. It was, according to an earlier page in the journal, the copied diagram of an Inuit map where the Adelaide seal hunters had obtained the ruthenium they oddly called Black Kobluna.

Zak matched the contours with a modern map of the islands and identified the targeted spot slightly west of their landing site.

“ The mine should be a half mile or so down the coastline,” he announced after the group had hiked over the ice to a rock-covered beachfront. “Keep your eyes open.”

Zak marched off down the beach ahead of the geologists, anxious to make the discovery himself. The cold seemed to fade away as he envisioned the potential riches that waited just down the coast. Goyette would already owe him for ridding the Canadian Arctic of American investors. Finding the ruthenium would be frosting on the cake.
