A map of the discoveries made by Capts. Cook & Clerke in the years 1778 & 1779 between the eastern coast of Asia and the western coast of North America when they attempted to navigate the North Sea, also Mr. Hearn’s discoveries to the north westward of Hudson’s Bay.

Scarce map of north-west America and north-east Asia, showing the tracks of the Resolution 1778-1779 based on Cook’s chart which was one of the great contributions to the charting of North America.

While searching for a north-west passage, Cook charted the Alaskan coast, east to Hudson Bay and the north-east coast of Asia including Kamchatka. His chart confirmed the absence of the much sought after Northwest Passage. The map also includes Samuel Hearne’s who was the first European to reach the shore of the Arctic Ocean by an overland route. By tracing the Coppermine River to the Arctic Ocean he had established there was no Northwest Passage through the continent at lower latitudes.
