Thompson map, 1814 |
|
Taught by Philip Turner, David Thompson surveyed for the HBC in northern Saskatchewan and Manitoba before he transferred to the Northwest Company in 1797. Over the next 15 years he surveyed from Lake Superior to the Pacific and, during several years in the Cordillera, unravelled the complex drainage basin of the Columbia River. The map above is a redrafted portion of Thompson's monumental map of northwestern North America. |
