The Mystery of Zewapeta
Zewapeta appears on maps in a location north of Commerce in Scott County, Missouri. Because Commerce is 39 and a half miles north of the mouth of the Ohio, and the locations on maps place Zewapeta at River Mile 41 or 42, the location is too far upstream for Hamtramck’s estimate. Nonetheless, it is only an estimate.
