Important map of Guillaume de L'Isle corrected by Philippe Buache and edited by Dezauche in 1783 ,after the conclusion of the American revolutionary war and the treaty of Paris Dezauche updated the new frontier from the 1703 original first De L'Isle drawing .This map is full of interesting historical fact , one is the doubt express by De L'Isle about Baron de Lahontan presumed " great northern passage " supposed to connect to the Pacific , another is the report that there was native town and large presence of native in Louisiana .Overall a fascinating map to study.Although Delisle depicts the river and indicates the point at which the Baron de Lahontan's journey is supposed to have ended and the point his reports from Native American information began. De l'Isle himself is skeptical, stating: "…a moins que le dit Sr. de Lahonton n'ait invente tout ces choses ce quil est difficile de resoudre etant le seul qui a penetre dans cest vastes contrees" ("Unless the Seigneur de Lahonton has invented all of these things, which is difficult to resolve, he being the only one who has penetrated this vast land.") The map includes a note referring to a large body of salt water to the west--"…sur la quelle ils navigant avec de grands bateaux"-a possible, early reference to the Great Salt Lake or a tantalizing hint of access to the Pacific. The cartouche include the " fleur de Lys " since the French revolution did not occur yet . It would make a great set framed on a wall .
