1,000-year-old archaeological site bulldozed during construction of Mexico-US border wall

On 24 April, a Department of Homeland Security contractor bulldozed a 1,000-year-old intaglio—a 280ft by 50ft etching in the desert sand—during construction of the US-Mexico border wall in Arizona's Cabeza Prieta National Wildlife Refuge. The site, sacred to local Indigenous communities including the Hia-Ced O’odham, was part of a UNESCO biosphere and contained over 3,000 petroglyphs. Despite warnings from tribal members and refuge staff, the contractor destroyed a 70ft stretch of the fish-shaped intaglio, which elders and archaeologists describe as an irreplaceable cultural and archaeological treasure.
