Alice Cunningham Fletcher observed in her 1902 publication in the American Anthropologist that there is ample evidence that some ancient cultures in Native America, e.g. the Pawnee in Nebraska, geographically located their villages according to patterns seen in stars of the heavens. See Alice C. Fletcher, Star Cult Among the Pawnee--A Preliminary Report, American Anthropologist, 4, 730-736, 1902. Ralph N. Buckstaff wrote: "These Indians recognized the constellations as we do, also the important stars, drawing them according to their magnitude. The groups were placed with a great deal of thought and care and show long study.... They were keen observers.... The Pawnee Indians must have had a knowledge of astronomy comparable to that of the early white men." See Ralph N. Buckstaff, Stars and Constellations of a Pawnee Sky Map, American Anthropologist, Vol. 29, Nr. 2, April-June 1927, pp. 279-285, 1927. In our book, we take these observations one level further and show that megalithic sites and petroglyphic rock carving and pictographic rock art in Native America, together with mounds and earthworks, were made to represent territorial geographic landmarks placed according to the stars of the sky using the ready map of the starry sky in the hermetic tradition, "as above, so below." That mirror image of the heavens on terrestrial land is the "Sky Earth" of Native America, whose "rock stars" are the real stars of the heavens, "immortalized" by rock art petroglyphs, pictographs, cave paintings, earthworks and mounds of various kinds (stone, earth, shells) on our Earth. These landmarks were placed systematically in North America, Central America (Meso-America) and South America and can to a large degree be reconstructed as the Sky Earth of Native America.
