Phoenix's history runs deep. Block 23, otherwise known as that empty parking lot next to CityScape, has seen its share of activity over the years: a theater, a JCPenney, and, before that, the city's first fire station. But when construction crews broke ground for what will eventually become a mixed-use development, they uncovered something older than all the previous tenants combined: five Hohokam pit houses believed to date back as far as 300 B.C. The site was remarkably intact given the centuries of activity above, but takeaway artifacts were few and far between. And while construction ultimately resumed, tearing up the remaining houses in the process, archaeologists were able to preserve some shards of pottery, which will be recorded, carbon-dated, and eventually gifted to the Pueblo Grande Museum.
