Canada's real-life Indiana Jones reminds us that the age of exploration is not over. When Adam Shoalts ventured into the largest unexplored wilderness on the planet, he hoped to set foot where no one had ever gone before. What he discovered surprised even him, and made him a media sensation. What struck a chord with people was the realization that the world is bigger than we think. We assume that because we have mapped it from space, it must be exhaustively known. But it is wilder, stranger, less homogenous than we assume. We hardly know it. And, contrary to popular wisdom, it is certainly not flat. In other words, the age of exploration is not over.
