A Caltech professor who outraged Native American tribes by drilling holes in an ancient petroglyph site while doing research without a permit near Bishop, Calif., has issued a public apology, saying he was “horrified” by what he had done.
“While the area’s geology is of significant interest, it is also of cultural and historical importance,” the scientist, Joseph Kirschvink, wrote in a statement. “I am horrified that I inadvertently collected samples from a sacred area that I too cherish and respect. I sincerely and deeply apologize for the disturbance we caused.”
But even as Kirschvink and officials at Caltech seek to make amends for damage caused at a protected archaeological site, a growing number of Indigenous groups and academics say more needs to be done to protect cultural resources from unfettered scientific inquiry.

What caused residents to abandon the ancient settlement that made the area near Cahokia, Illinois, home to the biggest city in the Western world? At its peak approximately 1,000 years ago, the settlement was bigger than London. But by A.D. 1400, it was virtually deserted.
Cahokia’s collapse has long been a subject of speculation. For several decades, one of the most persistent theories has blamed self-inflicted ecological disaster. First suggested by researchers at Southern Illinois University-Edwardsville in 1993, the theory held that the Mississippians who inhabited the city cut down forests in the nearby uplands, leading to erosion and flooding.
But the evidence underlying the theory was negligible, said geoarchaeologist Caitlin Rankin. The researchers knew that the people living in the area used wood, and that “there was increasing use of upland trees, happening more towards the end of Cahokia’s occupation,” she explained on Tuesday’s St. Louis on the Air.

One by one, the archaeologists stumbled upon pieces of junk. Using techniques typically reserved for documenting stone tools and bones, the team recorded such items as plastic spoons, eye glasses, bottle caps, straws, mobile phone batteries, paint can lids, candy wrappers, and plastic wrap. By the time the experiment was over, the archaeologists had uncovered nearly 3,000 items, the vast majority of them made of plastic.

Native American use of galena at Kincaid Mounds, a settlement occupied during the Mississippian period (1150 to 1450 CE), resulted in more than 1.5 metric tons of lead pollution deposited in a small lake near the Ohio River. New data from IUPUI researchers found the lead did not originate from this Southern Illinois settlement, but instead was brought to the site from other Midwest sources.

A project to produce detailed maps of all the land on Earth through laser scanning has been revealed by researchers who say action is needed now to preserve a record of the world’s cultural, environmental and geological treasures.
Prof Chris Fisher, an archaeologist from Colorado State University, said he founded the Earth Archive as a response to the climate crisis.
