In spring (September to November), soil conditions have abundant snow on the approach.

The best time is in January and March, where the approach is snow free, except for some specific areas, and the climate is more stable.

[1] During a flight from Santiago, Chile, to Mendoza, Argentina, on 16 July 1932, the Pan American-Grace Airways (Panagra) Ford Trimotor San José crashed on Cerro El Plomo during a severe snowstorm, killing all nine people on board.

The mountain achieved its fame in 1954 when a mummy of an approximately nine-year-old child was found on the summit.
