latest discovery from the site is the best find yet: a burial pit of the Delmarva Adena culture radiocarbon dated to 80 to 240 CE. Actually there are five or six such pits at the site, only one of which has been excavated to date.
What Delmarva Adena means is much disputed, and it is a very interesting question. To begin with, what was Hopewell culture about in its homeland? I follow the interpretation of Robert Hall, who argued that the extraordinary funerals of the Mound Builders were part of their political system. In many Indian societies, political transitions were managed largely through funerals and fictive kinship. When a big chief died, a new man would assume his identity and name, and then ceremonially renew his relationships with important allies, vassals, and so on; in Indian parlance these people were now his brothers, children, cousins, or whatever kin term seemed appropriate for the relationship. These political ties were cemented at the funeral, so men with big ambitions had to stage very impressive funerals for their predecessors.
