San Pablo is a dormant volcano located in the Antofagasta Region of Chile, near the Bolivia border. It is joined to the younger San Pedro volcano by a high col. It is located in the Chilean province of El Loa, city of Calama and Ollagüe. [6]
San Pablo was active in pre- glacial times. After that period, glaciations formed a girdle of moraines and the mountain was covered by ash fall from neighbouring San Pedro. [7] Its central crater was eroded and a glacier formed inside. The volcano itself is formed by three groups of andesite lavas which variously contain pyroxene or hornblende; these groups are known as the Lower Group, the Middle Group and the Summit Group. [8]
San Pablo was first climbed by Hans Berger (Germany) in September 1910. [3] [4]
It has an official height of 6050 meters. [9] Other data from available digital elevation models: SRTM yields 6098 metres, [10] ASTER 6076 metres [11] and TanDEM-X 6143 metres. [12] The height of the nearest key col is 5302 meters, leading to a topographic prominence of 808 meters. [13] San Pablo is considered a Mountain Subgroup according to the Dominance System [14] and its dominance is 13.22%. Its parent peak is San Pedro and the Topographic isolation is 5.1 kilometers. [13]
