Elk Point lies on I-29 in the narrow southeast finger of the state, between
Vermillion and
Sioux City, Iowa, with Nebraska on the west. It is the county seat of
Union County, in the
Dakota Heritage & Lakes Region.
Elk Point is famed for its role as a major stopping point of the Lewis & Clark Expedition, which camped there on the way west in 1804, and on the return trip in 1806. The city hosts a Lewis & Clark Heritage Days festival each August.
