Spirit Mound is a distinctive geological formation known as a roche moutonée. This means it's a bedrock knob that was shaped, but not leveled, by the last Pleistocene glacier approximately 13,000 years ago. This unique glacial sculpting contributes to its prominent hill shape on the Great Plains.

The primary and most popular trail is the .75-mile path leading directly to the summit, which is designated a National Recreation Trail. While there aren't extensive networks of other marked hiking trails, the 320-acre prairie offers opportunities for exploration off the main path, especially for those interested in birdwatching or observing prairie flora and fauna.

The restored prairie is home to a rich variety of wildlife. Visitors often spot prairie wildflowers, Fritillary butterflies, and numerous bird species. Other prairie animals also inhabit the area, making it a great spot for nature observation.

Spirit Mound holds deep historical significance, particularly for Native American tribes who believed it was inhabited by 'little people' or 'devils.' It is also famously one of the few places where historians can definitively say the Lewis and Clark Expedition stood, having visited it on August 25, 1804, to investigate the legends.

No, there are no fees or permits required to visit Spirit Mound Historic Prairie. It is a state park that is free and open to the public.

Spirit Mound is unique among Lewis and Clark sites because it is one of the last remaining locations where visitors can walk in the exact footsteps of the expedition and witness a landscape that closely resembles their descriptions. Many other areas visited by Lewis and Clark along the Missouri River are now submerged due to damming, making Spirit Mound a particularly well-preserved historical landmark.
