Following his return from participating in John Franklin's first overland expedition (1819–1822), Willard Wentzel, a clerk for the North West Company, produced a map of the Mackenzie River and a brief account of its geography, native peoples, and history and significance as it related to the North West Company. This map and the account, which is one of the few early descriptions of the Mackenzie River area, are held in the Royal Commonwealth Society Papers at the University of Cambridge. They have not previously been published.
