David Thompson (1770-1857) spent much of his career as a company man and clerk. He avoided battles with native Indian tribes and rival fur traders. But Thompson was still a true mountain man who, in the late 18th and early 19th centuries undertook extraordinary explorations of the rivers, lakes, and wilderness of the Canadian and Oregon territories, overcoming the hardships of bitter winters, lack of food, and unforgiving terrain. His masterwork, the great map of the Canadian West remains a treasured artifact of Canada’s history and heritage.
Author D’Arcy Jenish tells Thompson’s tale in a bright, straightforward narrative that quotes liberally from Thompson’s Narrative of his explorations, written in his old age, and from the detailed journals that he maintained for many years. It is a rich resource. After a while, however, someone like me, unfamiliar with Canadian topography, can become dizzy with even Thompson’s routine canoe trips on icy rivers and narrow lakes, portages around waterfalls, and treks through forests and snowfields.
Ironically, a book about a celebrated cartographer lacks any contemporary maps that would allow us to trace Thompson’s travels, such as this typical excursion: “Grand Portage to Pigeon River to Rainy River to Lake of the Woods and down the Winnipeg River to the big lake of the same name … up the Dauphin River to Lake Manitoba…” and finally to a post on Swan River. And we haven’t even gotten to Thompson’s later journeys around Lake Athabasca, much less his trek over the Rockies to the Columbia River in Oregon. He never lost a man on any of these expeditions.
Thompson was first employed as a clerk tallying trade good and fur pelts with the Hudson’s Bay Company, then later joined their rival, the Montreal-based North West Company. His true love, however, was exploration and surveying to make maps of the vast Canadian interior from Hudson’s Bay and Lake Superior to — in an epic march — the Oregon coast and the mouth of the Columbia River. (He was bitterly disappointed when the later U.S.-Canadian Boundary Commission drew the border at the 49th parallel, ceding the Oregon Territories to America.)
Thompson the man — stoic, low-key yet driven — remains opaque in Jenish’s account. We learn of Thompson’s frustration when weather or distance frustrated his travels, but little of the interior man. He loved astronomy, even apart from using the sextant for mapping. One First Nation tribe gave him the name “He Who Looks at Stars.” He had a successful marriage, although several of his children did not survive to adulthood. Of his wife, Charlotte, we learn little, except that she supported Thompson’s career and travels without serious complaint. Apparently, Thompson’s journals are all business, with few if any private asides.
The descriptions of encounters with First Nation peoples, however, are fascinating. Native tribes were numerous, greatly outnumbering the European traders from the Hudson’s Bay and North West companies. The tribes essentially functioned as independent contractors who supplied the prized beaver pelts and other furs in exchange for manufactured trade goods like clothing, and more crucially, guns and liquor.
For native tribes like the Peigon — part of the Blackfoot Confederacy — access to weapons and horses could tip the scales in their constant warfare against their rivals. Thompson, fluent in French and several Indian languages, negotiated with these tribes very carefully, even with the constant provocation of horse theft. The traders’ most common ploy was alcohol, although Thompson, a teetotaling Christian, was vehemently opposed to providing liquor to his own men, much less Indians.
After twenty eight years of wilderness trekking and surveying, Thompson retired to prepare his great map. The “Map of the North-West Territory of the Province of Canada” measures six feet-nine inches by ten feet-four inches, and provides a detailed and highly accurate depiction of the Canadian West. Nothing like it existed at the time. Thompson received gratitude but little remuneration for his efforts, and after a succession of business failures, he and his family fell into bankruptcy.
Only in recent years, with publication of Thompson’s narrative of his travels, has he achieved widespread recognition for his achievements, both as an explorer and mapmaker.
