This chart details the St. Lawrence River just northeast of Quebec City and Ile d'Orleans, which is the large unnamed island at far left. The chart shows a number of small islands in the St. Lawrence to the east-northeast of Ile d'Orleans. Three navigable channels are identified -- the Iberville Channel, the "ancient" channel, and the "traverse" channel hugging the northwest shoreline. Rococo-style cartouche is inland of the shoreline and a fleur-de-lys lies above the intersection of rhumb lines.

An excellent example on watermarked paper with wide margins and a few spots of foxing confined to the blank margins.
