2012 Peru

The Chimú resided on the north coast of Peru: "It consists of a narrow strip of desert, 20 to 100 miles wide, between the Pacific and the western slopes of the Andes, crossed here and there by short rivers which start in the rainier mountains and provide a series of green and fertile oases." The valley plains are very flat and well-suited to irrigation, which is probably as old as agriculture here. Fishing was also very important and was almost considered as important as agriculture.
