geoglyph
JEE-oh-glif
A large design or motif made on the ground by arranging stones, scraping away surface material, or shaping earth — generally too large to be read from the ground and only fully visible from the air. The Nazca Lines of Peru are the most famous, but geoglyphs are found on every inhabited continent, from the chalk figures of southern England to the stone-lined "Works of the Old Men" across Arabia to the Amazon rainforest clearings now being revealed by deforestation.
Etymology
From Greek geo- (earth) + glyphē (carving). The word is modern — coined by archaeologists to describe something ancient.
Notes
The American Southwest alone contains over 600 intaglio-type geoglyphs.
