[Aztlan] Jalisco pecked cross circles count calculation from Joseph Mountjoy

[michael ruggeri]

Sid:

      Turns out I copied the information wrong for the posting.  There  
are 84 pits in the interior circle of the Cerro Chapin design, not 80   
There is, however, a wrinkle to the Cerro Chapin calculation.  The  
Kelleys got 260 by counting the central pit as "0", otherwise, as they  
note, the total count would be 261.  I recounted the Purificación  
petroglyph pits, and assuming symmetry the total count would be 265,  
including the central pit.  Nonetheless, each of the Purificación  
circle-and-cross petroglyphs would seem to have different total  
numbers, although it is hard to calculate on most due to problems of  
incomplete preservation.  I plan to return to Purificación in 2010 to  
recheck the ones we have registered, and to register those remaining  
in the area we have not yet seen.  With all the interest in this  
subject, the Purificación circle-and-cross petroglyphs would seem to  
merit a more careful study, and publication.  Joe.

The part that I was "missing"  was how you got a sum of 260 when the  
sum is actually 256?
