NAZCA Geoglyphs Permanent

Why don’t NAZCA erase?

The lines are known as geoglyphs – drawings on the ground made by removing rocks and earth. The rocks which cover the desert have oxidized and weathered to a deep rust color, and when the top 12-15 inches of rock is removed, a light-colored, high contrasting sand is exposed. Because there’s so little rain, wind and erosion, the exposed designs have stayed largely intact for 500 to 2000 years. However, in addition to personal injury such as driving in, it is also considered that the loss by El Nino phenomenon.
