Highly detailed regional map of Alaska showing the region from Prince Frederick Sound in the North to Queen Charlotte's Island and the contiguous Pacific Coast of Canada in the south, and including Juneau, Sitka, Ketchikan, etc.

The chart is one of the sectional charts from the French edition of Vancouver's Voyages and comprise the first detailed printed maps of the regions covered.

During the summers of 1792-94, George Vancouver and the crew of the British ships Discovery and Chatham mapped the northwest coast of North America from Baja California to Alaska. Vancouver's voyage was the last, and longest, of the great Pacific voyages of the late eighteenth century. A skilled and competent sailor and explorer, Vancouver eliminated the possibility of a Northwest Passage. His remarkably precise surveys completed the outline of the Pacific.
