Today, Spirit Mound is one of the few remaining physical features on the Upper Missouri River that is readily identifiable as a place Lewis and Clark visited and recorded.
Spirit Mound is located approximately six miles north of Vermillion, on Hwy. 19. A state park, Spirit Mound Historic Prairie, was established, and the landscape is being restored. An interpretive sign is located at the I-29 Information Center near Junction City, and a small parking lot and day use area will be established by 2004 at the NW corner of the intersection of Hwy. 19 and 312th St.
