Join us at Fort Ancient Earthworks & Nature Preserve, 6123 State Route 350, Oregonia, on July 3 at 12 p.m. for Blazes in the Woods with Historian Keith Bengtson. As we celebrate the 250th anniversary of our country, Bengtson will explain why the Fort Ancient Earthworks began in what is now Virginia.

Visit a recreated surveyor’s camp to learn how Ohio’s land was divided, try hands-on measuring activities to see the size of an acre and explore how Native American techniques may have been used to create precise earthworks 2,000 years ago.
