Rare map of the United States with inset maps of the region around Washington DC, Boston, Philadelphia and New York. The map is not only rare, it includes nice detail, including Forts, Indian Villages, Towns, Roads, Railroads, Canals, Waterfalls, Ports, Universities and Colleges and other features. Very nice detail along the Upper Missouri River and in Oregon Territory, which shows in its 54-40 or Fight pre-1846 configuration. Two Salt Lakes and rivers connecting each to the Pacific Ocean are prominent in the Cartography of California. Texas' border appears to track the Neuces River. Several Plains Indian boundaries are shown, along with a Lewis & Clark note or two. A wonderful scarce map, last offered in a dealer catalogue in 1989. Minor crease.
