In late February, Ajo Station agents patrolling on foot came across what they believed to be an ancient bowl hidden in a shady outcropping of rock, the Border Patrol said.
Officials from the Organ Pipe Cactus National Monument were notified and identified the clay vessel as an olla, an ancient pot that was used to hold water and was stored in shade to keep the water cool, the Border Patrol said.
Agents patrolling in the same mountains in March discovered a second site with similar artifacts that were hidden in the entrance of a cave. The agents photographed the objects and passed the photos along to Organ Pipe officials for removal and preservation, the Border Patrol said.
