Irrigation canals in ancient Peru?


The initial discovery was made in 1989, but it took years of further excavations, radiocarbon dating and other analysis before Dr. Dillehay felt ready to announce the find.

"We wanted to make sure that the dates were correct and to find more early canals," Dr. Dillehay said. "There are now four sites with canals and probably more."

From this interesting article about a recent paper on the discovery of irrigation canals that existed some 4000 to 6400 years ago in what is now Peru.
