More from Jim Allen's website:

Geoforms - agricultural formations on the Bolivian Altiplano

Contrary to the opinions of some modern scientists that the Altiplano was a place unsuitable for agriculture, satellite imagery shows that practically every square foot of earth, whether on level ground or steep mountainside, has been cultivated at some time in the past. Although the impression on the ground may be of an abandoned empty desert at times, the satellite imagery shows there must have been an occupation in the millions of people - who developed many diverse forms of agriculture varying from the mountain terraces for which the Andes are famous, maze-like parcels of raised land surrounded by irregular water channels called "suka kollus", regular plots of land bounded by parallel straight canals, modified mountains with artificial radiating walls, irregular stone walled enclosures, irregular irrigated mountainside plots, artificial fish ponds with interconnecting channels, semi-aquatic cultures living on artificial islands, regular and irregular modern field patches.
Some of the old patterns have been eliminated by later cultivations but many can be still detected on the satellite imagery, which also shows up extensive earthquake damage in places where old terraces have been virtually demolished and in others where ancient iregular walled fields have been buried beneath extensive sand dunes.
