Nevado Sajama is an extinct
stratovolcano and the highest peak in
Bolivia. The mountain is located in
Sajama National Park in the southwest area of the country some 16-24 km (10-15 mi) from the border with
Chile. The structure of the peak is complex, with
lava domes of
andesitic and
rhyodactic composition overlain by an andesitic stratovolcano. The date of the most recent eruption is uncertain, although
Holocene activity is assigned to the volcano by many.
Joseph Prem made the first attempt to climb the mountain in
1927 by the northwest ridge but was stopped short at 6,200 m. After several more attempts, Prem along with Piero Ghiglione reached the top in August 1939 by a more difficult southeast ridge.
