Exhibits at the Museo Arqueológico, run by the University of Buenos Aires, can be a little confusing due to a lack of explanatory labels. The two mummies here are considerably less well cared for than those in Salta's MAAM (Museum of High Altitude Archaeology), but no less fascinating. The clothes, hair, and skin of the first, which was found in San Pedro de Atacama in Chile, are well preserved. Other rooms display Nazca, Inca, Moche, and other remains from the past 2,000
years. Keep your ticket stubs, as they'll get you in to the nearby Pucará de Tilcara ruins, where some of this museum's artifacts were discovered.
