Peter, I read this morning about Federal officials that mistakenly published confidential information on locations and descriptions of about 900 ancient cliff dwellings, spiritual structures, rock art panels and other Native American antiquities in Utah. The Bureau of Land Management posted a 77-page report online that included unique identifiers for priceless artifacts as it prepared to auction the most archaeologically rich lands ever offered for industrial use. The report exposed ruins spanning 13,000 years of Native American history to vandalism and looting, and experts say the BLM violated federal regulations that prohibit publicly sharing information about antiquities.
