This is a wonderful article surrounding the discoveries by archaeologists in Phoenix from under a parking lot which is being replaced by commercial
buildings.
The parking lot protected the finds which produced many wonderful pieces of history and unlocked some prehistoric pit houses as well.
There is a short video piece at the link for those interested.

The prehistoric pit houses, a century-old cosmetic-cream jar and antique bricks tell the story of the first merchants in downtown Phoenix.
Archaeologists earlier this month found those artifacts deep beneath the downtown parking lot where on Monday crews will begin building a $900 million
hub of shops, offices and restaurants.
