Peru's Chan Chan Archaeological Zone, site of what was the largest earthen architecture city in the pre-Columbian Americas, recently offered up a new surprise for archaeologists: a mass grave with the skeletal remains of 25 mostly young female members of the Chimu civilization.

Investigators at the Chan Chan site, located in the northwestern Peruvian region of La Libertad and inscribed on Unesco's World Heritage List in 1986, documented in October a multiple funerary context within the excavations of the Utzh An (big house in the Chimu language) citadel, or earthen-walled complex.
