Well-preserved child mummy

I thought perhaps this was a Chachapoya "cloud mummy," but the National Geographic site indicates that the mummy is from Argentina:

They are perfectly preserved child mummies unearthed on top of a volcano in northwest Argentina. As young as 6 years old, these three children were chosen to die as an Incan sacrifice to their gods.

This girl is 500 years old and looks quite fresh, suggesting to me that desiccation is more important to preservation of flesh than any of the other maneuvers performed by Egyptian priests.

The full program is due to air in July, and sounds quite interesting.
