This uncommon map exhibits some speculative cartography on the Pacific coast of North America, including an appearance of the Sea of the West. A huge Mer ou Baye de l'Ouest dominates the northwest coast, but a tentative coastline also reflects the Russian discoveries in the region. The large inset map illustrates the theories of Joseph Delisle and Philippe Buache concerning the potential Northwest Passage and the Sea of the West. In the Pacific, the tracks of early explorers are shown, including Quiros, Mendana, Le Maire, Magellan, and Antoine.
