Due to the expected snow & ice, slick sidewalks and parking lots are likely to exist @ all three sites (Seip Earthworks, Hopewell Mound Group & Mound City). Crews will be working to mitigate any slippery surfaces. Please use caution when visiting. More »
There is a strong consensus in the fields of ecology and conservation biology that invasive exotic species pose one of the greatest threats to the integrity of native ecosystems in the U.S. and around the world. Among the most notable effects are modifications of competitive interactions, promotion of invasion by other non-indigenous plants and animals, hybridization with native species and consequent alteration of the gene pool, changes in the physical structure of ecosystems and communities, increased erosion, shifts in phenology, new disturbance patterns, and altered successional paths.

The first publication of the Smithsonian Institution in 1848 was an extensive survey of archeology sites that included all of the sites at Hopewell Culture NHP. The book was authored by Ephraim Squier (left) and Edwin Davis (right), residents of the town of Chillicothe where Hopewell Culture NHP is located.
