Doane Robinson, who had investigated the pre-settlement history of the Upper Missouri Valley thoroughly and intelligently, had this to say in his History of Dakota regarding the fur trade in the Northwest and how it influenced settlement of the area: “From 1764, the French of St. Louis begun trading up the Missouri. There is very little of record indicating how far up the river this trade extended, but it is certain that long before 1800 they were trading within the South Dakota Territory. Loisell’s Post, a strong, fortified trading house,was built on Cedar Island in the Missouri River, thirty-five miles below Pierre, in 1796. In the fall of 1796, Treaudeau, a St. Louis trader, established a house for trade with the Pawnees on the east bank of the Missouri, and a little above the site of Fort Randall . . . . It may be said that it is highly improbable that South Dakota was explored by the Spaniards in the early portion of the sixteenth century, or that any white man saw the territory during the sixteenth century at all.”
