___ Lines (ancient Peruvian geoglyphs)

NAZCA

These mysterious desert etchings, best viewed from above, were created by a pre-Inca civilization and include designs of animals and geometric shapes.

This clue refers to the famous Nazca Lines, a series of massive ancient geoglyphs etched into the desert floor of southern Peru. The blank signals you’re looking for a single word that completes the phrase, and "Nazca" fits as both the name of the civilization and the location. The lines, created over 2,000 years ago, depict animals, plants, and geometric shapes visible from the air.
