The Nazca Lines are a series of ancient geoglyphs located in the Nazca Desert in southern Peru. They were designated as a UNESCO World Heritage Site in 1994. The high, arid plateau stretches more than 80 kilometres (50 mi) between the towns of Nazca and Palpa on the Pampas de Jumana about 400 km south of Lima. On the ground, most of the lines are formed by a shallow trench with a depth of between 10 cm (3.9 in) and 15 cm (5.9 in). Such trenches were made by removing the reddish-brown iron oxide-coated pebbles that cover the surface of the Nazca desert. When this gravel is removed the light-coloured clay earth which is exposed in the bottom of the trench produces lines which contrast sharply in colour and tone with the surrounding land surface. This sublayer contains high amounts of lime which, with the morning mist, hardens to form a protective layer that shields the lines from winds, thereby preventing erosion.
