Teuchitlan
Recently excavated in December 1999.
Some details of the excavation:
"Guachimonton is the nickname given to the circular architecture of the Teuchitlan Tradition, the name given to the largest of the circles at this site (as noted by Adela Breton at the turn of the century - Huaerchimonton), and the name given to this site. It is the largest and most complex site with this architecture, and is located in the center of the Tequila valleys, in the very greatest concentration of public and residential architecture in the region. The map really only depicts the central collection of public architecture, but smaller circles and residential architecture are continuously and closely distributed over a large area beyond this. The section shown here sits on the slopes just behind the town of Teuchitlan and the site is sometimes referred to by this name."
