29 déc. 1791 - David Thomson
Description:
In 1790, with his apprenticeship nearing its end, Thompson requested a set of surveying tools in place of the typical parting gift of fine clothes offered by the company to those completing their indenture. He received both[12]:10-11. He entered the employ of the Hudson's Bay Company as a fur trader. In 1792 he completed his first significant survey, mapping a route to Lake Athabasca (where today's Alberta/Saskatchewan border is located).[13] Between February and May 1793, Thompson made 34 observations of the longitude of Cumberland House using lunar distances.Ajouté au bande de temps:
