The Arc of Appalachia Preserve System manages 14 nature preserves throughout southern Ohio.

The Arc of Appalachia Preserve System

The Spruce Hill works are owned by the Arc of Appalachia Perserve System and co-managed by Hopewell Culture NHP and Ross County Park District. Spruce Hill is one of the best remaining examples of hilltop enclosures fabricated by the Hopewell Culture. The non-profit Arc of Appalachia Preserve System was founded in 1995 as a grassroots organization to preserve forest and associated Eastern eco-systems, as well as ancient earthworks and historical buildings. Visit The Arc of Appalachia website to learn more about their organization. Read the Spruce Hill story to discover how The Arc rescued the site from auction.

Ohio History Connection

Since the early 20th century, much of the Seip Earthworks unit was owned by the Ohio History Connection (OHC) (formerly known as the The Ohio State Archaeological and Historical Society and the Ohio Historical Society). Between 1992 and 2014, The National Park Service partnered with the Ohio History Connection in co-owning and co-managing the Seip Earthworks site.

More recently, after a decades worth of arranging and planning, the deed of ownership to Seip Earthworks was officially transferred from OHC to the National Park Service on September 3, 2014. Even though the government-owned majority of Seip Earthworks is now solely under the possession and management of Hopewell Culture NHP, we will continue our proud partnership with OHC in meaningful and creative ways to preserve and protect the remnants of the Hopewell Culture.

Ross County Park District

Recreational trails at the Hopewell Mound Group are the result of a partnership with the Ross County Park District. This partner helped convert a mile of abandoned B & O railroad corridor to the Tri-County Triangle Trail. The Ross County Park District also co-manages Spruce Hill works with Hopewell Culture NHP and the Arc of Appalachia Preserve System.
