A couple of months ago, the BBC reported new findings on puquios, which are spiralling holes scattered across Peru’s Nasca region. Through satellite imagery, a team of Italian researchers deduced the purpose of the once-mysterious holes: based on their placement and proximity to settlements, puquios seem to be part of a complex water retrieval and distribution system.
The BBC report carries a standout quote from the lead researcher:
“What is clearly evident today is that the puquio system must have been much more developed than it appears today,” says Lasaponara.
There are a lot of other notable quotes regarding this breakthrough, but that one dredged up a memory from one of the anthropology classes I took in college.
