When the "real" map came to light, the 1681 map, now known among scholars as the Thèvenot Map, was until the mid-19th century thought to be an engraving of a legitimate map of Marquette. Now called the Thèvenot Map, it has recently been put up on the Library of Congress map site. What this 1681 map affirms is the Jesuit's limited knowledge of the continental interior. This map, based on the Manitoumie Map, exists in several versions, the circumstances of its creation have yet to be studied.

More accurately, the most advanced knowledge of the continental interior in the early 1680s was the result of the explorations of La Salle. Whether disingenuous or naive, the Jesuits, and others, have, to our day, claimed for Jesuit Father Jacques Marquette the honors rightfully due Robert Cavelier, Sieur de La Salle.
