Map of Eastern Canada extending above the Arctic Circle, derived from de l’Isle’s landmark map of 1703. There is much uncertainty regarding the western shore of Hudson Bay, and Baffin Island is split into three parts.

Early settlements are shown at Detroit and Chicago. The source of the Mississippi is indicated, although too far west.

The fabled river to the West, as described by Lahontan, is pictured leading to the Rockies. Beyond lies the Great Salt Lake, described according to native reports. The map is filled with geographical and historical notes, and a large inset contains a summary of major events in the discovery and exploration of Canada.
