In January, excavation at the Pima County Regional Wastewater Reclamation Facility at Ina Road and Interstate 10 revealed the ancient irrigation system. It is said to be the most intricate system of its kind uncovered in North America.
“We’ve uncovered dozens of these fields. We can see the actual holes where they planted the corn in many instances” geologist Fred Nials said. “We can completely reconstruct their irrigation system.”
