A post journal of 1799–1800 mentions people trading at the post who can be identified as the ancestors of members of the former Fort St John Band, now the Doig River and Blueberry River First Nations. Doing oral history confirms that the ancestors of present Dane-zaa families were in the upper Peace River area prior to the first contact by Alexander Mackenzie in 1793. Traders provisioned their expeditions with bison meat and grease provided by the Dane-zaa in their hunting on the rich prairies of the upper Peace River area. By the time the Hudson's Bay Company took over the North West Company in 1823, bison were scarce.
