Marking Sioux Falls History: The Amidon Affair
One of Sioux Falls most prominent landmarks is the Pioneer Memorial of the Amidon Affair located in northern Sioux Falls just south of St. Michael Cemetery on bluffs overlooking the Big Sioux River.
The current memorial was erected in 1991.
According to the Minnehaha County Historical Society and the South Dakota State Historical Society the 1862 Sioux Uprising, a result of unjust government treatment, claimed many Indian and non-Indian lives.
Near this place on August 25, 1862, two of its victims, Judge Joseph B. Amidon and his son, William, were killed while making hay on their claim which was a mile north of their cabin in Sioux Falls.
