This is only the eastern two-thirds of this famous and extraordinarily accurate first map of the Trans-Mississippi West. It was published in the second London edition of "Travels to the source of The Missouri River and Across the American Continent to The Pacific Ocean performed by order of The Government of the United States in the years 1804, 1805, and 1806. By Captains Lewis and Clarke. Volume I." It was engraved by Samuel John Neele and published by Longman, Hurst, Rees, Orme & Brown in 1815. It covers the area between Lake Superior to St. Louis, centered on the Missouri River and tributaries, and extending to the Rocky Mountains with extensive notes concerning the epic expedition. The map is very rare and generally found in very poor condition. Therefore, even though this is but a part of the map, it is still a fascinating part of U.S. history and a great addition to any Americana collection. Includes photocopy of the title page.
