Nanchoc District
Nanchoc is located in an irrigated and cultivated valley about 1 kilometre (0.62 miles) wide and 60 kilometres (37 miles) from the Pacific Ocean to the west. Between the valley and the ocean is a low range of mountains and the Peruvian coastal desert. East of Nanchoc the Andes rise sharply and the greater precipitation in the Andes feeds the Nanchoc River and its tributaries, permitting irrigated agriculture to flourish in the valley.
History
Nanchoc district was created 2 December 1958 by Law No. 13039 del 2, during the second government of President Manuel Prado Ugarteche. At the time the district included the population centers of Carahuasi, Bolívar, El Espino, Trigal, La Aventuraza, El Diamante, La Tambora and Tingues. Most of these communities were separated from Nanchoc district in 1989 and placed in Bolivar District.
Archaeology
On the western side of the Nanchoc river, about 3 kilometres (1.9 miles) from the town of Nanchoc, archaeologist Tom Dillehay found evidence of the oldest known irrigation canals in the Americas, radiocarbon dated to at least 3400 BCE and possibly as old as 4700 BCE. The canals built by the people of Nanchoc at that time were utilized to irrigate crops such as peanuts, squash, manioc, and chenopods, a relative of Quinoa.
