“Map of Missouri River and Vicinity from St. Charles to the Mandan Villages of North Dakota made by James Mackay (1759-1822) with the assistance of John Evans (1770-1799).” This detail shows Missouri River roughly between the Platte and Kansas Rivers.
In January 1796, James Mackay of the Commercial Company for the Discovery of the Nations of the Upper Missouri, a Spanish enterprise commonly called the Missouri Company, made a voyage up the Missouri River, accompanied by James Evans (1770-1799). The most important material outcome of their expedition was a remarkably precise and detailed map of the Missouri River from St. Charles to the Mandan villages, which quickly was recognized as the most accurate made up to that time. Mackay, who had turned back at Fort Charles, the trading post he built on the Missouri somewhere between the mouths of the Platte and Niobrara Rivers, drew the final version. It included many of the early French names of the Missouri’s tributaries. Thomas Jefferson sent a copy of it to Meriwether Lewis in 1803. It was one of the most valuable tools the captains had.

Clark’s Fort Mandan Maps
by Joseph A. Mussulman
While wintering over at Fort Mandan, Clark made a series of maps based on Indian information and previous traders such as John Evans and François Larocque.
The Corps of Discovery had been, as James Ronda phrased it, “only the latest in a long series of traders and travelers” to visit the tribes living along the Missouri. The Mandans had been visited in 1738 by la Vérendrye from his base on the Assiniboine River.
