[.ca] First Across the Continent: Sir Alexander MacKenzie (ISBN 0806130024)

From Amazon.com:
The first white man to cross North America, Scottish-born Alexander Mackenzie (1764-1820) was typical of his generation of explorers: this bold adventurer who surveyed the untamed wilderness with impressive accuracy was also a hardheaded businessman who ventured into unknown Canadian territory in search of profits from fur trading. Canadian historian Barry Gough admires Mackenzie's toughness and daring without glossing over the towering ego and knack for self-promotion that won him a knighthood from England in 1802. First Across the Continent is another enjoyable entry in the University of Oklahoma's Western Biographies series.
