Hiking & Exploring Seip Earthworks

This large earthwork complex once contained a low embankment forming a small circle and an irregular circle and a square, all connected and enclosing about 121 acres. Within the enclosure was a large elliptical mound, three smaller conjoined mounds, several small mounds, and several structure outlines, all found through excavations. It is estimated that the large mound (Seip Mound) was originally 240 feet long, 160 feet wide, and 30 feet high.

Today, the reconstructed Seip Mound and a portion of reconstructed wall are visible. Additionally, a portion of original wall is visible near Dill Road on the eastern edge of the property. The nature trails located throughout the site offer interpretive panels with information about Seip Mound and details about what has been discovered since the original excavations of the site in the late 1920's. A pavillion with a number of picnic tables is available on a first-come, first-serve basis and is located adjacent to the parking lot.
