Burial towers

Burial towers or chullpas have been used for millenia in parts of the altiplano for burying the dead, and still are today in some areas. These are two of the many found in the Desaguadero River valley, which is the main watercourse in the region and flows from Lake Titicaca (its only natural outlet) to Lake Poopo near Oruro.
