Chacaltaya (Aymara for "cold road") is a mountain in the Cordillera Real, one of the mountain ranges of the Cordillera Oriental, itself a range of the Bolivian Andes. Its elevation is 5,421 meters (17,785 ft). Chacaltaya's glacier - which was as old as 18,000 years � had in 1940 an area of 0.22 km (0.085 sq mi), reduced to 0.01 km (0.0039 sq mi) in 2007 and was completely gone by 2009. Half of the meltdown was done before 1980 (measured in volume). The final meltdown after 1980, due to missing precipitation and the warm phase of El Ni?o, resulted in its final disappearance in 2009. The glacier was one of the highest glaciers in South America, located about 30 kilometers (19 mi) from La Paz, near Huayna Potos� mountain
