On July 9, the Corps of Engineers repatriated a large cache of sacred artifacts to the Navajo Nation. The Omaha District, with some assistance from the Albuquerque District, returned the artifacts in accordance with the Archaeological Resources Protection Act. The artifacts were looted from Corps of Engineers-managed land and Navajo tribal lands. A total of 710 artifacts were recovered from lands managed both by the Corps of Engineers and the Navajo Nation. Out of these, 425 were determined to be the property of the Navajo Nation, and were returned.
