You get an expansive view of Ajo's ugly gash of an open-pit mine, almost 2 miles wide, from the New Cornelia Open Pit Mine Lookout Point. Some of the abandoned equipment remains in the pit, and mining operations are diagrammed at the volunteer-run visitors' center, where there's a 30-minute film about mining. The mine is always "open," but the visitor's center hours are sporadic. The mine is about a mile southwest of the plaza; take La Mina Road or Estrella Road to Indian Village Road.
