This is the first map reporting the last two expeditions of La Salle which related La Salle’s celebrated Mississippi exploration and became the first accurate delineation of the river system of the vast French empire. In spite of the hardships of Joutel in making his way back to Canada after the tragic death of La Salle and the breakup of the ill-fated expedition, he produced a fine account and one of the best maps to his time of the Mississippi River.
