Nasca Lines, Peru

March 31, 2003
This ASTER sub-image covers an area of 14 x 18 km, and was acquired on December 22, 2000. The data were processed to create a simulated natural color presentation. The Nasca Lines are located in the Pampa region of Peru, the desolate plain of the Peruvian coast 400 km south of Lima. The Lines were first spotted when commercial airlines began flying across the Peruvian desert in the 1920's. Passengers reported seeing 'primitive landing strips' on the ground below. The Lines were made by removing the iron-oxide coated pebbles which cover the surface of the desert. When the gravel is removed, they contrast with the light color underneath. In this way the lines were drawn as furrows of a lighter color.
