Bishop Gregory J. Hartmayer of Savannah looks over an artifacts found on St. Catherines Island in Georgia Oct. 14. Looking on is archaeologist Matthew Napolitano of the American Museum of Natural History. Earlier in the day, the bishop celebrated Mass at the island’s historic mission site. The mission dates back to the 1570s and has been the subject of study by archaeologists for nearly three decades. Scientists on the island continue to excavate with a sense of urgency as erosion from rising sea levels threaten the remains of a vanished American Indian community.
