New day new ideas

Mom and I hiked back out to the site today. It was even hotter and muggier than yesterday but we pushed onward. Today we decided to start at the southern end of the earthworks and work our way inward. We probed and flagged two more possible pit locations.
Hiking in from the South gave us a better view of the ravines that are running through the area, there are three ravines that run through the middle of the enclosed space. We probed some more and took photos. Then went to the observation deck which is in the southern half of the earthworks right on the cliffs. Looking down from this vantage-point really put a new perspective on the entire thing. If this were a fort how could people from the village site across the river see what was coming? How could they scale the 100-foot high shale bluffs in a timely manner. This site would not be one that you could easily access from the river. You can get to it, but it would be difficult. I'm looking into reformatting my research question a little bit to possibly include an analysis and comparison of the earthworks as a ceremonial site to other known earthworks sites along the Olentangy and Scioto rivers. The more I walk around this site the more I think that this is a ceremonial site and not a fortification.
Another exciting discovery was made by mother who took a look at Baby's field notes that are located int the Ranger station/Nature center. As we walked through the woods to the site we ourselves noted that there seemed to be a second ring of earthworks, or at least what looked like some. Baby, in his notes, says that there is in fact a second ring and that he excavated a trench from one ring to the other. This discovery has prompted me to look over Baby's notes again in the OHS, so I will organize a time sometime this week and hopefully find something I did not the first time.
This, accompanied by the fact that the location is hard to get to and that the center of the earthworks is red clay, something not local to the park itself, makes me believe even more that this is a ceremonial site and not a fort.
I'm going to be researching a lot more in the next week or so and looking into links between this and other sites in the area.
