The structures that look like domed bread ovens
Might be just that for cooking tortillas. Common for flatbreads in the middle east. Found pics in search for "adobe ovens" and "cob ovens" but couldn't get pics to show with the link
Thanks for the links to the map for the village., and the post has great pics from the flick.
In the pics, I think it is a corn crib that Calvera and his men are riding past - easily done with stained matchsticks cut to length. Nearby there are many examples of what looks like vegetation tied up in pyramid shape

The grouping and location suggests that isn't where they grew. Anyone know if that's how they dried corn on the stalk before harvesting the cobs?
Tinned Fruit - thanks for the close-ups of the individual buildings. Great pictures.
