San José Mogote was the first major cultural center of the Zapotecs in the Etla valley of Oaxaca. There is evidence of a farming community as far back as 1500 BC, and significant political power with the attendant construction of temples, etc, beginning in 1300 BC, or 800 years prior to Monte Alban. Most of the site has yet to be unearthed, which is probably a good thing, as INAH, the Mexican governmental agency tasked with administration and protection of such sites, has barely enough to continue operating established tourist operations. There was no controlled entry here at all, and paths cris-crossed the entire site, with grafitti defacing some upper walls.
I chose to present these in B&W to accentuate the age of the site. Afterwards, we walked around the town of Guadalupe Etla a bit.
I really hope INAH gets the funding they need to properly excavate and preserve this and other priceless heritage sites around Mexico. It would be a shame to lose this history.
