Recovering the raised fields - Peru

Google Maps give beautiful pictures of the Earth. We have seen and shown in several posts that the satellite eye is able to display in great detail the archaeological remains and ruins. Let me show you here three images of some raised fields near the Lake Titicaca. These waru-warus (raised fields in Aymara language) are near Caritamaya.

According to a private communication (ConNuestroPeru), the archaeologists

are recovering some waru-warus having circular and radial shapes.

In fact, several waru-warus create geoglyphs featuring animals. 

The "raised fields" are earthworks separated by canals. 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.
