Members of an Argentine indigenous organization are trying to legally block the display of the remains of 500 year old Inca children at the Museum of High Altitude Archaeology in Salta, saying it dishonors their "little brothers and sisters." Rival museum officials in Buenos Aires dismiss the exhibit as morbid. And the explorer who discovered the bodies six years ago worries that a rushed showing could permanently damage them.

Their facial features are clear, and their muscles are firm. The blood remains frozen in their veins, and the vivid clothes they wore the day they died remain intact.

The three Incan children -- believed to be victims of a mountaintop sacrifice about 500 years ago -- are among the best-preserved mummies ever found.
