Fort Lisa

The first Fort Lisa (1810-1812), also known as the Fort Manuel Lisa Trading Post, Fort Manuel or Fort Mandan, was started by the notable fur trader Manuel Lisa of the Missouri Fur Company in 1809. This fort was likely where Sacagawea died; she had been the guide for the Lewis and Clark Expedition. Fort Lisa superseded Fort Raymond as the uppermost post of the Missouri Fur Company on the Missouri River. This original fort, believed to be where Sacagawea died, was located near present day Kenel, South Dakota. It was not in North Dakota, and every source available places it in South Dakota. In 1812 Lisa built a replacement fort downriver near present-day North Omaha, Nebraska, which he also named Fort Lisa.
