Explorer, fur trader, and mapmaker David Thompson was a pivotal figure in the early exploration of Canada and the Northwestern United States and is considered by many as “the greatest North American land geographer of his time.” Thompson and his party were the first Europeans to travel the full length of the Columbia River.

KSPS's Uncharted Territory explores Thompson’s relationships with Native peoples of Canada and North America and sheds light on his dynamic accomplishments as explorer, astronomer, surveyor, and mapmaker. The documentary focuses on the years 1800-1812—the time period that he explored the Kootenai area of Alberta, south through the Inland Northwest and down the Columbia River to the pacific. 

Help students use primary and secondary sources to gain a deeper understanding of David Thompson’s explorations and contributions with these video segments and accompanying learning guide. Visit KSPS Education for additonal educator resources.
