Beautifully engraved, large-scale, map featuring the coastal topography from Point Arena to just below the mouth of the Columbia River. The track of Vancouver's exploration in 1792 is shown complete with soundings. Inset of "Baie de la Trinidad". During the summers of 1792-94, George Vancouver and the crew of the British naval 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. Taking the art and technique of distant voyaging to a new level, Vancouver eliminated the possibility of a Northwest Passage and his remarkably precise surveys completed the outline of the Pacific.
