Grave Creek Mound

In the mid-1800s several stone towers were found along the Ohio River near Moundsville, West Virginia where the massive Grave Creek Mound is. This is an 1840s illustration by Schoolcraft of a stone tower on a mountain overlooking Moundsville. It is thought that they were used a lookout stations.
