Detailed map of the North Pacific, based upon the explorations of James Cook in his third Voyage.
Hawaii (Sandwich Islands) are shown, as is the Coastlines of the Northwest part of America and the Northeast Coast of Asia, in remarkable detail for the period.
Many place names are given along the coast, much of which is laid down with much greater accuracy than earlier maps. The known and conjectural coasts of California, the Northwest and Alaska are delineated, reflecting the significant advances in the knowledge of the coastline, yet at the same time leaving significant room for improvement over the coming decades.
The Russian explorations along the Northeast Coast of Asia in the first half of the 18th Century are in evidence. In addition, the discoveries noted by the Spanish are annotated, some real, some mythical.
