Sairecabur proper is accompanied by a wide caldera. Before the formation of this caldera the volcano may have been high and thus one of the highest volcanoes on Earth. After the formation of this caldera lava effusion occurred during the Pleistocene and Holocene; there is no reported historical activity, however. Eruption products on Escalante and Sairecabur include andesite and dacite. The climate is dry, cold and very sunny.
