Archaeologists study ancient Hohokam find

PHOENIX Archaeologist Mark Hackbarth had expected to find Hohokam ruins on the site for the new Phoenix Convention Center.
But he never imagined the immensity of the find. Over 30 days this summer, Hackbarth uncovered 40 of the earliest known Hohokam pithouses in the Phoenix metropolitan area. They are three thousand years old.

Now, thousands of artifacts from the dig rest in a Tempe laboratory.
