El Misti, also known as Guagua-Putina
El Misti has three concentric craters. In the inner crater fumarole activity can be seen. Near the inner crater six Inca mummies and rare Inca artifacts were found in 1998 during a month-long excavation directed by the archaeologists Johan Reinhard and Jose Antonio Chavez. These findings are currently stored at the Museo de Santuarios Andinos in Arequipa.
There are two main climbing routes on the volcano. The Pastores route, which is more used, as its starting point is nearer to the city of Arequipa, starts in 3,300 metres (10,800 ft). Usually a camp is made in 4,500 metres (14,800 ft) at Nido de Aguilas. The second route, the Aguada Blanca route, starts at 4,000 metres (13,100 ft) near the Aguada Blanca reservoir and a camp is made in 4,800 metres (15,700 ft) at Monte Blanco (the name of the camp comes from the fact that it has more or less the height as the summit of Mont Blanc). Neither climbing routes presents technical difficulties but both are considered strenuous because of the steep loose sand slopes.
