Fort La Jonquière was one of the two French forts established on the Saskatchewan River in the 20 years between the end of La Vérendrye's push west from Lake Superior in 1731-1743 and the fall of New France in 1763. The other was Fort de la Corne built two years later. It was the westernmost French fort in Canada and was named after Jacques-Pierre de Taffanel de la Jonquière, Marquis de la Jonquière who was the Governor General of New France at the time. The problem is where was it?
