Andenes as level curves, near Ayacucho, Peru
After processing a Google Maps image.

"Andenes are terraces dug into the slopes of mountains for agricultural purposes. They were constructed and much used in the Andes mountain range to provide cultivable hillsides. The majority of these terraces were constructed and used by the pre-Hispanic cultures, and many can still be observed throughout the region."
