@inti I call this Pueblo Colorado Circle. Are #geoglyph or #intaglio better?
Another #GreatCircle on #PachaMama. Outlines in my graphic are relative sizes.
#Stonehenge fits inside the tiny circle beside #NewarkOctagon.

@inti
Another #GreatCircle etched on #PachaMama, smaller than Tumi Chucua #Zanja, larger than the #Newark Great Circle. The three circles in my graphic illustrate their relative sizes.
The tiny circle in the center is the margin of error for their center-on-center arc distances ratio from Eagle Mound at the center of Newark's Great Circle. The ratio is #Phi squared to one, 2.618034 to 1.0.
Phi is 1.618034...
