Antisana

Antisana is a stratovolcano covered with a glacier, 5753 meters high. Located west of the recently discovered Aliso volcano. Antisana arose in the Late Pleistocene and was formed in 2 stages. The southeastern part of the volcano is the oldest and occupies most of the volcano. It consists of frozen lavas, pyroclastic flows , breccias . The volcano was modified as a result of the appearance of a glacier, which was preceded by 2 explosive eruptions on the eastern and southern calderas of the volcano. The northwestern slope of the volcano is the youngest and you can see a cone-shaped relief on it. It contains a large number of frozen lavas that flowed from the summit cone of the volcano. The composition of the cured lava consists of porphyrites .

One eruption of the volcano officially occurred in 1801-1802. Then the lava flowed out of the volcano cone along the western slope and traveled a length of 15 kilometers.

For the first time, the peak of the volcano was conquered on March 9, 1880 by the English explorer Edward Wimper and the Italian climber Jean-Antoine Carrel .
