In Salta, the high-mountain archaeological museum (MAAM) was created after the discovery, in 1999, of three mommies of children from the Inca civilization on the Llullaillaco, the third highest active volcano in the world (6.739 m), after the Ojos del Salado and the Pissis.
A special sarcophagus has been set to keep and exhibit the mommies: only one of them is exhibited, then changed every six months. They are in exceptional state. A special sarcophagus is prepared to preserve the mommies while exhibiting them: only one of them is exhibited, then changed every six months.
