Heather Pringle, the terrific western Canadian writer who has made herself one of North America's leading archaeology journalists (yes, there is such a thing) covers the demolition of a treasure of American archaeology to provide dirt fill for a new Wal-Mart building project. It's not new, but I just came across it, and no one else seems to have mentioned it.
Update, August 7: For a sense of the history being destroyed, consider Timothy Pauketat's new study of Cahokia, the 12th century city state located near what is now St. Louis, Missouri.
