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 (and Ponca at the time), Quapaw, Kansa, Osage, Arikira, Dakota, and Cheyenne people inhabited and settled the region previous to Europeans and European descendants. Numerous burial mounds still exist on the high bluffs near the river and are spread throughout the general vicinity.
Currently, the area is suffering a draught, the water level was much lower than expected.
Last time I was here I was 10, proudly wearing a turquoise cowgirl hat and a Ballard Bulldog sweatshirt (my grammar school) standing next to my sister.
