Found this little map when researching canals:
Drawn by Dr. Omar Turney in the 1929 of the canals dug by the Hohokam's of (now) Arizona.
-Rob A>One of the most prominent features of Hohokam culture is a vast network of hand-dug irrigation canals. The main canals fed thousands of smaller ditches that brought water to an estimated 25,000 acres of cultivated fields. The Hohokam established villages at regular intervals along the main canals to create a complex, interlocking social and economic system that provided them with great success for many years.
