Seeking the Northwest Passage and the fabled link to Russia, Japan, and Cathay, Alexander Mackenzie drove himself and his men relentlessly, by canoe and portage, across the uncharted rivers, valleys, and mountains of North America. Mackenzie's 1789 journey to the Arctic Ocean and his arduous journey to the Pacific in 1793 predate the Lewis and Clark expedition. By the age of thirty-one, Alexander Mackenzie had become the first man to cross North America from the northwestern hub of the interior trade, Lake Athabasca, to the Pacific Ocean. He had opened the continent to trade and exploration. In his research, Barry Gough traveled from Mackenzie's birthplace to his tomb and from Montreal to both the Arctic Ocean and the Pacific. He takes the reader along with Mackenzie on his hazardous travels and voyages, using contemporary accounts to bring to life the perils faced by the young explorer. First Across the Continent reveals the international impact of Sir Alexander Mackenzie's expeditions and places him among the elite of New World Explorers, illuminating his vital role in the history of the fur trade and the American West.
