Highly detailed regional map of the west coast, extending from Bodega Bay, California, to just south of the mount of the Columbia River.
The map tracks the Columbia River to P. Vancouver, showing the area around today's Portland, Oregon. Cape Lookout is named, as are Mount Hood, Cap Foulweather, Cap Perpetua, Cap Gregory, Cap Oxford, Port St. George, Trinidad Bay, Cape Mendocino, and Point Arena. Bodega Bay is illustrated but unnamed.
Large inset map of Trinidad Bay.
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.
