First Permanent Fur Post


PIERRE, S.D. – The first settlers within the present boundaries of South Dakota were French fur traders, who established a fur post on Cedar Island on the Missouri River in 1802, roughly 20 miles below Pierre.

The area in which the fur post was established was part of Louisiana, receded by Spain to France in 1800 and ceded by France to the United States in 1803.  In accordance with the wording on the historical marker located 20 miles down river from Pierre on S.D. Hwy 34, Lewis and Clark stopped at this fur post on September 22, 1804.

Trade activity at the fur post on CedarIsland went on until 1810.  In 1817, Joseph La Frambois established FortTeton on the present site of FortPierre, and settlement has been continuous since.
