The summit crater of Las Pilas volcano (also known as El Hoyo) is 700 m wide and about 120 m deep. A prominent fumarole on the SE side of the crater emits a steam plume. Beyond and to the right of Las Pilas is the 900-m-high satellitic cone Cerro Ojo de Agua, itself capped with a 400-m-wide crater. The diagonal line cutting across from the summit crater of Las Pilas to the lower right was formed during an eruption in 1952.
