Spirit Mound Trust


The little hill known by the Sioux as Paha Wakan was held in awe by tribes for miles around. The Omaha, the Sioux, and the Otoes believe that the mound was occupied by spirits that killed any human who came near.


Spirit Mound is located five miles north of Vermillion, SD. It is one of the few known places Lewis and Clark absolutely stood on their journey West. It is the first place where they observed tallgrass prairie from a high vantage point, and the first recording of a herd of buffalo by the Corps of Discovery. 

Formerly a feedlot, the Spirit Mound Trust has been working to restore Spirit Mound to the conditions Lewis and Clark experienced over 200 years ago, and to promote the beauty and history of Spirit Mound. The Trust works closely with the South Dakota Department of Game, Fish, and Parks.

The Trust works to promote and educate locals and visitors to the site about the historical and cultural significance, geology, and ecology of the area.
