"Chart of the Northern Passage between Asia & America", Thomson, John

Very informative map showing the development of the Alaskan and northwest coastline. Alaska is still a bit misshapen with virtually no interior topography. The tracks of Cook's voyage in 1778 and 1779 are traced and in the Arctic is a note of McKenzie's discoveries. The watercourse from Slave Lake to the Arctic Sea is shown, along with interesting anecdotal notes ("Mountains with bright stones" and "According to Indian Report, a Sea a short way to the West"). Includes great detail of the Pacific coast with the exception of Puget Sound, which is quite tiny.
