Adam Shoalts was no stranger to the wilderness. He had hacked his way through jungles, stared down bears and climbed mountains. But, one spot on the map called out to him irresistibly. Cutting through the forbidding landscape of the Hudson Bay Lowlands is a river no hunter, no explorer, has left any record of paddling. It was this river that Shoalts was obsessively determined to explore.    

What Shoalts discovered as he paddled downriver appeared in no satellite imagery or map: a series of waterfalls that could easily have killed him. Just as astonishing was the media reaction when he got back to civilization.
