"Map of Lewis and Clark's Track across the Western Portion of North America, from the Mississippi to the Pacific Ocean, By Order of the Executive of the United States in 1804, 5, & 6."

A black and white engraving measuring 6" x 13 1/2”, this 1842 map is reduced from the original map of the same title, first published in 1814.  The map was published in Lewis and Clark's “History of the Expedition under the Command of Captains Lewis and Clark…” written by Archibald M'Vickar and published by Harper and Brothers, New York. It was engraved by W. G. Evans.

The map is filled with interesting annotations, such as this entry northwest of Council Bluffs: "Here the different Tribes meet in Friendship & collect Stone for Pipes", and "Here Capt. Clark made canoes to descend the R.", noted alongside the Yellowstone River. Indian tribes, forts, rivers, and creeks are located on the map, including “Monnels Ft.” near the Yellowstone River. 

Lewis and Clark laid to rest the dreams of a navigable water route to the Pacific. They did, however, find several routes through the mountains, which could be used by future explorers or emigrants going to the Oregon country. They also made cartographers realize that the Rocky Mountain range was wider and further from the Pacific than had been previously thought. 

The map’s principal impact to the cartography of the United States is its delineation of the Missouri and Columbia River systems and of the Rocky Mountains. By invigorating an interest in the newly acquired territory of Louisiana and in the Oregon country, Clark’s map became a factor in the Westward Movement. 

The original 1814 map was more accurate than any previously published western map and it rapidly became the source for a whole new generation of western maps.
