A hand colored navigational map of the Pacific coast of the United States, primarily Washington and Oregon. The map includes vast detail along the coast and is less detailed further inland. Coastal cities and towns, water depths, reefs, lights, and buoys are shown. A table of tidal information and seven inset maps are included. The inset maps show Duncan Rock and Cape Flattery, Grays Harbour, Orford Reef, Humboldt Bay, and the entrances to the Umpqua River, the Yaquina River, and the Coos River. Two coastal views are included: Cape Flattery and the entrance to Humboldt Bay. Relief is shown by hachures and spot heights. Depths are shown by soundings in fathoms.
