presenting my revised decipherment of the Cahokia mounds as an Earth Sky Map based on a new map of the mounds sent to me by Steve Burdic (the old decipherment is here).
The maroon, purple and green elements (mounds and lines) are from Burdic's original map. I have added the blue (arrows), red (constellation lines) and black (text explanatory) materials.
The basic decipherment has remained the same, although there are some small additions, and this map will be much easier for most of you to read and understand than the previous one.
There is now no doubt in my mind that this decipherment is correct, since it fits in a number of new elements from Burdic's new map which I was not familiar with before, but which integrate without problem into the previous decipherment.
Steve Burdic suggests that there may also be solar alignments present, and I do not doubt this, but this is not my major scope of interest and I thus leave that research to others.
The Cahokia mounds are seen as being relatively recent by the archaeologists (ca. 800 to 1400 A.D.), but there is no question that the cardinal stellar positions used for the stars must date back much further in time.
