PROLOGUE

Here we have reached the remotest region of the earth … a wilderness without a footprint.

—Aeschylus, Prometheus Bound, fifth century BC

AHEAD OF US LAY the pitiless expanse of frigid ocean known as Hudson Bay. Behind us lay countless miles of windswept tundra, trackless swamp, and impassable muskeg. Half-famished polar bears roamed the desolate coastline. It wasn’t a place one should travel alone—or at all, really.

For the past two weeks my friend and expedition partner Brent Kozuh and I had been hacking and paddling our way across this still largely unexplored wilderness, battling hypothermia and insufferable clouds of mosquitoes and blackflies.

Once we reached the bleak shores of Hudson Bay, Brent finally cracked.

I had seen this moment coming—for the past few days he had fallen into a stupor, his resolve corroded by the millions of bloodsucking insects and the grimness of our journey. We were ankle-deep in icy water, dragging a heavily laden canoe behind us while staggering against fierce winds sweeping off the sea when Brent finally seized up altogether.

“Adam,” he said mechanically, “I can’t go on … I want to go home.”

“We can’t quit. We haven’t reached the river yet,” I replied.

“I don’t care about the river. This is about survival. Let me have the satellite phone. I’m going to call a pilot and try to get him to land here.”

The wind howled across the treeless tundra, biting into our bearded faces. For a fleeting moment, I thought about Brent’s proposal to abandon the expedition. But as I stood there shivering in the salt water, I felt I would never be able to live with failure. I needed to reach the river we had come to find.

“No,” I said shaking my head, “quitting isn’t an option.”

“What does it matter? We’ve done enough,” Brent said.

“We’ve barely done anything.”

Brent didn’t reply. To him, the nameless river we were seeking wasn’t some priceless prize, but just another subarctic river like all the others we had paddled since we began our journey. To me, however, this river represented something more—it was a mystery, and a promise of a pristine place untouched by the modern world, a river so obscure that no known person had ever previously explored it. That made it irresistible. But I could see that all Brent had in mind when he thought of another river was more discomfort, more cold, more swarms of mosquitoes and blackflies.

So I tried to appeal not to the explorer in him, but to the athlete. To quit now, I told him, would be to admit defeat. It would open the door for someone else to explore the river instead of us. Brent slouched down against the canoe’s oak gunwale. “No one in their right mind is ever going to do that.”

“Someone has to do it,” I replied.

Brent sighed, “It doesn’t have to be me.”

My feet were numb from standing in the cold water. With the sun sinking below the horizon, I was keen to get moving. “Let’s push on a little farther. We’ll make camp, get a fire going, warm up, and then you’ll feel better.”

Brent didn’t budge. “I won’t feel better until I’m home on my couch with a roof over my head.”

“There’s the rest of your life for that. This is a chance to do something different.”

Brent just stared at the canoe. The wind continued to howl around us. We both shivered in the cold. Snow geese flapped across the sky. I scanned the tundra in either direction. There were no bears in sight.

“Each day feels like an eternity out here,” mumbled Brent. “It’s freezing, I’m hungry, tired, and wet. There are polar bears all over the place, and we’ve no idea what might be on that river.”

“Things will get easier. We’ve just had some bad weather,” I replied, but without much conviction, knowing that things would likely only get worse.

“Adam,” Brent said slowly, “sometimes you’re insane.”

“I can’t do this alone.”

Brent shook his head, “I can’t do this at all.”

Clearly, appealing to Brent’s competitive side would now get me nowhere. So I appealed to the one thing I thought he still valued: “If you quit now, you’ll have to pay for the entire cost of the flight out of here. The Geographical Society won’t cover any of it. It’ll cost you a fortune.”

“I’d gladly spend my entire life’s savings to get out of here.”

“You’d really leave me alone in polar bear territory?” I was grasping at straws.

“There’s no reason you can’t get on that plane with me.”

“Not until we’ve succeeded.”

Brent just kept staring at the frigid sea. I was sympathetic. I knew he was cold. I knew the truth of his words—a day can drag on endlessly when you’re hungry, exhausted, and wet. When you have only the dimmest sense of what lies ahead. When polar bears are stalking you. I knew it must be hard to put one foot in front of the other if you aren’t drawn magnetically toward your destination—as I was.

Brent tossed his hands in the air. “We can just lie about it. We can say we explored the river.” His expression finally showed some life.

“Brent!”

“What?”

“We obviously can’t do that.”

“Who’d know?”

“We’d know.”

It became clear that nothing would convince Brent to push on deeper into the wilderness. His will was broken, his mind made up. Now I had to accept the inevitable. To argue any further while standing idly in the estuary would just give us both hypothermia. “All right,” I said after a very long pause, “we’ll head back to the old goose hunting shack and you can try to contact a pilot.”

With that, we grabbed hold of our loaded canoe and dragged it back upriver, wading through frigid water and fighting our way up several sets of rapids to the relative safety of a dilapidated hunting cabin. The next day, I knew, the pilot would arrive for Brent … but I wouldn’t be getting on that plane with him. Daunting as I found the prospect, I would have to remain behind to somehow finish the expedition on my own.

As of tomorrow, I’d be alone against the North.
