The Big Sioux River serves as the winding natural boundary between Lincoln County and Lyon County, marking the border between South Dakota and Iowa. This modern landscape is defined by its agricultural grid and the preservation of natural corridors along the river valley. The small settlement of Granite is situated in the north, while the locality of Klondike sits to the south where Klondike Creek meets the river.
