A 3,000 year old settlement with an extensive canal system has been discovered in Arizona.
The settlement dates from at least 1200 B.C., during an era of Southwestern history archaeologists call the Early Agriculture Period.
Positioned near the confluence of the Cañada del Oro, Rillito Creek and Santa Cruz River, research at the site has provided scientists with a glimpse into the transition from roaming bands of hunters and foragers to a society of skilled farmers — a snapshot of human progress in the Southwest.
