Monte Sierpe, also called the Band of Holes, is a long line of more than 5,200 pits in southern Peru. Each pit is about one to two meters wide and up to one meter deep. The site became well known after National Geographic published aerial photos in 1933.
A new study published this month in Antiquity combined sediment analysis and drone photography. Scientists found microbotanical traces of maize and wild plants used for weaving and packaging. Drone images show the rows are segmented and follow a clear mathematical pattern. Researchers suggest local groups used the holes to store goods and keep counts for trade or tribute.
