Thank heavens for archaeologists. Those digging near the old Mission San Agustín uncovered 2,000-year-old arrowheads mere feet from a 1930s barbecue pit.
The project by Desert Archaeology Inc. gives more evidence to the belief the Tucson area is the longest continuously inhabited region in the U.S., stretching back at least 4,000 years.
The new evidence also shows multiple eras of human beings in one spot going back 2,500 years or more.
The work precedes reconstruction of the mission as the crown jewel in Tucson Origins Heritage Park for the Rio Nuevo development.
Many findings now being unearthed in the core of our city are priceless relics of our extraordinarily deep roots. Tucson is wise to ensure such exploration before construction.
In appreciation we will not comment on the lame joke. That's the whole thing, too.
