Nice example of Lizars map of Canada, Alaska and the Polar Regions.
Excellent early map of Canada, Alaska and the Northwest part of America and contiguous regions covered by Lewis & Clark.
The map provides a fine treatment of the search for the Northwest Passage and the progress of the Hudson's Bay Company in its exploration and exploitation of Western Canada.
The treatment of Western Territory (Oregon Territory) is excellent quite nice topographically, correctly placing the Fraser River and the Columbia, and showing a credible course of the Missouri River and tributaries. 54-40 or fight Oregon Territorial Border. The river from San Francisco to Salt Lake still appears. A N.W. Company outpost is shown. Alaska is Russian Territory.
The NW Coast of America and northern coast of Alaska and Northern Canada are treated in excellent detail. Marvelous detail east of the Canadian Rocky Mountains. A terrific regional map with excellent detail for the period.
