Which Flag Really Flew Here? | The Flags of Elk Point

Eight flags fly in a circle in a little park in Elk Point, South Dakota. Every one of them once claimed the ground under your feet — France, Spain, France again, the United States, and the Yankton and Ponca nations who were there before any of them. And one flag in that circle has not a word about it anywhere online. We walk the circle and ask every flag two questions: how did you come to hold this ground, and what is still a mystery?
