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]

Elevation
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]
