This is an old photograph of women
Please contact me if you know anything about this.
I have found an alternate old photo, this one with a chinampero along the chinampas. Maybe I will post it at some point.
And what does this have to do with Calixtlahuaca, you might ask. Well, the lakes around Tenochtitlan, and in the southern part of the Basin of Mexico, were filled with chinampas in Aztec times. The high productivity of this form of agriculture is one reason why Tenochtitlan conquered Calixtlahuaca, rather than the other way around.
