“We want to show you some petroglyphs located not far from Arandas. We’ve never seen anything like them before.” This email message immediately grabbed my attention because it had been sent by two archaeologists, Rodrigo and Cyntia Esparza. If the Esparzas considered this rock art extraordinary, I told myself, it must be extraordinary indeed. So, I made an extra effort to try to set up an expedition to Arandas—no easy task because the site was at the end of “un camino feo” (literally, an ugly road) and only high-clearance vehicles would be suitable for reaching the place.
