Where did the Nazca Lines on the Peruvian Plains Come From?

The Peruvian coastal plain in South America is home to a wonder of archaeology.

The ground is scarred by images, or geoglyphs, known as the Nazca lines, thought to have been constructed by the people of Nazca between 500 BCE and 500 CE. The ancient artworks, most easily viewed from the air, were created by methodically removing dark colored gravel from the surface to reveal lighter material below.

The plains’ unique climate has preserved the lines for thousands of years.

Each year, the region receives just 20 minutes of rainfall on average, and the ground is mostly stone and gravel, which prevents the striking images from eroding in the wind.
