Notes from Baum Earthworks 2000


December 20, 2000. Having called yesterday and gotten permission from the owner of the land, Bob Jones, to explore the mounds, I took a taxi from the motel in Chillicothe. It was partly sunny and about 20 degrees out.
        I start the survey from the (closest to) south corner. The southwest side of the square, wall “E-G”, had a road built upon it, which is still present and in use. All references to gateway nomenclature herein are from the 1880s Middleton-Fowke survey as published by Cyrus Thomas in 1889 and 1894. I will refer to it as “the Thomas data”.
        It is easy to see the southeast wall, “G-A”, as it leaves the road perpendicularly.
When I was there, there were various areas of the field left in moderate stubble of hay of some sort, so not all segments of the earthwork were equally visible. For instance, starting on the crest of and adjoining the entire length of wall G-A on its southwest side was an area of unmown dead growth. Hence the width of this remnant section of the square could not be ascertained. Conversely, the northern parts of the square, northeast of the fenceline crossing the field, were virtually bare of growth and well seen.
        My goal was to replicate the Thomas data layout as per the lengths given. I did not measure the azimuths except very roughly (uncorrected, to a degree or two) with a hand held common compass. By measuring with a 100-foot tape, I was able to relocate gateways. The accuracy was probably good: a few feet at most over the 500+ feet between gateways.
        I began by measuring from the center of the road. This was the best guess since the road is over top of the wall. Following the Thomas data distance, I began measuring toward gateway H. The gateway was quite obvious and matched well the data. The width of the low gateway was still around 30 feet. I could not see the southwest side of the embankment aperture because of the aforementioned stubble and growth.
        Continuing on to gateway A, there is a problem. The Thomas figure puts the tape measurement into a large swale or ditch. The lease-farmer for this piece of land, George Vandermark, related that a prior owner of the land in decades past had rediverted the flow of a runoff creek in the area. In years past there had been a mill not too far away: flooding and water were and are facets of this landscape. The net effect being here is that we cannot be sure of the original placement of this corner of the square, gateway A. Subsequent measures toward gates B and C revealed this error at A by not matching up with the Thomas data.
        AS I measured toward gates B and then the corner gateway C, their placement did not match the Thomas data, at least relative to the best fit I could get on the location of the corner “A”. I am not confident of the location I determined for A.
Subsequent work to place it per the Thomas data could be explored using profession survey equipment by plotting the Thomas azimuths as well.
The wall A-C crosses a fenceline between gates B and C. Here near the fenceline, the embankment is still well pronounced. I have enclosed a photo of this section of the wall. The view of the camera angle is indicated on the site map. In the photo, the far wall of the square is notable as the road. Gateway B, by the way, is poorly defined. It is best noted as a lower area relative to the rest of the wall sections.
Finally arriving at corner gateway C, one sees the feature obviously. Both wall  B-C and wall C-D are distinct where they come close to form gateway C. The wall C-D is very apparent throughout its length. I measure along it following the Thomas data. I marked the gateway D with some stakes.
AT this point, I return to corner gateway G, the starting point. Now I measure back along the road to establish the loci of gateways E and F. It is easy to measure along the road, except for the few cars etc that go by. Gate F is highlighted on a detail map provided herein indicating local features along the roadside.
Corner gateway E is not on the road. The road bends just as it nears this corner of the square. A swelling in the land can be seen at the location of the destroyed corner. There are some buildings quite near not shown on the enclosed drawing. However, it is very easy to see along the bearing of the wall E-G by virtue of sighting along the road.
Sticking with the Thomas data, I measure now along wall C-E toward gateway D. There is excellent agreement with the survey stakes I placed there coming around the other side of the square earlier: the marks are virtually coincident.
Now I have established the axis of the avenue/square. This runs between gates H and D. Unfortunately, right before sunset it clouded over, so I did not get to make the winter solstice set observation!
