Gilles Robert de Vaugondy's rendition of Samuel Engel's map of 1764 with the Asian and American coasts slightly altered. The myth of a Northwest Passage continues to persist, here linking the Detroit d Anian with Lac Michinipi by a system of rivers and a large Lac des Conibas. There is also a River of the West that connects to another large lake, L. des Tahuglanuks that is located near a remnant of Lanhotan's R. Longue. Alaska is shown as a series of large islands. The Northwest coast is labeled Grand Quivira and the entire west is labeled Allies des Sioux.
