The Hopewell Culture National Historical Park, encompassing mounds for which the culture is named, is in the Paint Creek Valley just a few miles from Chillicothe, Ohio. Other earthworks in the Chillicothe area include Hopeton, Mound City, Seip Earthworks and Dill Mounds District, High Banks Works, Liberty, Cedar-Bank Works, Anderson, Frankfort, Dunlap, Spruce Hill, Story Mound, and Shriver Circle. When colonial settlers first crossed the Appalachians, after almost a century and a half in North America, they were astounded at these monumental constructions, some of which were as high as 70 feet and covering acres.
