Geoglyphs of Titicaca - 1

Earthworks near Titicaca Lake create "geoglyphs"

These earthworks are known as "raised fields" and "waru-warus".

The image, obtained from Google Maps, shows the network of earthworks separated by canals - near the Titicaca Lake (Huata, Puno, Peru). 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.
