History History of Sioux Falls, South Dakota Falls of the Big Sioux River The history of Sioux Falls revolves around the cascades of the Big Sioux River . The falls were created about 14,000 years ago during the last ice age . The lure of the falls has been a powerful influence. Ho-Chunk, Ioway, Otoe, Missouri, Omaha , Quapaw, Kansa, Osage, Arikira, Dakota, Nakota and Cheyenne people inhabited the region previous to European descendants. Numerous burial mounds still exist on the high bluffs near the river. These people operated an agricultural society that built fortified villages on many of the same sites that were previously settled. Lakota populate urban and reservation communities in the contemporary state and many Lakota, Dakota, Nakota, and other Indigenous Americans reside in Sioux Falls today. The first documented European visit was made by French voyagers/explorers, in the early 18th century, who mapped the area and took census counts of the Indigenous cities communities at that time . The first documented visit by an American was by Philander Prescott , who camped overnight at the falls in December 1832. Captain James Allen led a military expedition out of Fort Des Moines in 1844.
