Raised fields in Bolivia

The image shows the "raised fields" near the Titicaca Lake, in Bolivia.
Note the "snake": eye, tongue and teeth. 

This image, obtained after processing a Google Maps image, shows the network of waru-warus, that is, of the "raised fields" - earthworks separated by canals - near Tiwanaku. This is an ancient agricultural technique used by Andean people starting from the first millennium BC. Each raised field is approximately 10 meters large and more than one hundred long.
