Very informative and large 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. In the Arctic is a notation describing McKenzie's discoveries including a note where he reported seeing the sea on July 12th, 1789. The watercourse (MacKenzie River) from Slave Lake to the Arctic Sea is shown, along with interesting anecdotal notations (Mountains with bright stones, Strong Bow Indians 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.

A nice impression with contemporary color, some extraneous creasing, very light offsetting, and minor soiling. There are a couple of archivally repaired tears along the edges of the sheet and a damp stain confined to the bottom right margin.
