The ancient earthworks depicted to the left once lay along waters of the East Fork of the Little Miami River in Ohio, about 20 miles above its mouth near Milford, and about 25-30 miles east of Cincinnati. They have long since been plowed level, and their orientation and exact location are unknown.
Ohio had dozens of such large-scale earthworks, attributed to the Hopewell Culture of circa 100 BC to 500 AD.
The larger image in the link showing the entire area and multiple structures. The structure on the left, even with 9 on a clock, with a small circle. I use to live inside the small circle and is when the majority of my visions came to me.
