[Aztlan] AZ: Q Locks on Netzahualcoyotl's Dike- Lake Texcoco

[Tomas Filsinger]

Estimad at s listeros,

	I have been making some reconstructive maps of Tenochtitlan trying to 
incorporate all the information I have come across in several years of 
research, you can see a small  QTVR sample with four nodes or points of 
view (Chapultepec, Cerro de la Estrella, Cerro del Tepetzingo, Cerro 
del Tepeyac)  at:

http://www.mexicomaxico.org/Tenoch/qtvr.htm

I have incorporated the "compuerta" (lock?) of Atzacualco at its north 
end and the one near Iztapalapa in its south end.  My question is if 
anyone has come across any reference to the "compuerta(s)" they might 
have had in the center of the "dike" near the hill  "El Peñon de 
Tepetzingo"?

   I read that this hill was sometimes used as a beacon for dusk or 
night rowing and it seems logical to me to have one near there to avoid 
having to row to the north or south extremes (the dike was more than 12 
km long!), specially if one was heading to Tenochtitlan/ Tlatelolco 
from Texcoco or viceversa.

Any pointers would be greatly appreciated.
