Supplemental Graphic 5 - Arcs

As a further aid to visualizing any apparent “mirror imaging” between the N and S halves of the Circle, the following arcs are provided: A = normal aspect, S half drawing; B = flipped aspect N half drawing; C= normal aspect S half aerial photo; and D= flipped aspect N half aerial photo. There is simply no support for this thesis that I can see in these data. Weisman, et al (p. 343) do state that field observations supported their depiction. However, I myself, have worked extensively with this material both in the field and with later photo interpretations, and the “is it or isn’t it” decision making is just as indeterminate from photos as from life. And without defined parameters, the issues cannot be resolved.
