Image from Google Maps: a geoglyph near the Titicaca Lake, Peru.
This image shows a plain area covered by a network of waru-warus, that is, of the "raised fields" - earthworks separated by canals - near the Titicaca Lake. This is an ancient agricultural technique used by Andean people starting from the first millennium BC. Note that the structure of the network is created after a careful planning. Each raised field is approximately 10 meters large and more than one hundred long.
