Cerro Singüil (also known as El Cerron) is a large scoria cone SE of Volcán Chingo in the interior valley of El Salvador near the Guatemalan border. The volcano has a well-preserved summit crater and belongs to a young volcanic field of cinder cones and explosion craters.
A young basaltic lava flow, probably less than 10,000 years old, extends to the NNE down the valley of the Quebada La Presa, the headwaters of the Río Guajoyo. The Cerro Singüil volcanic field includes a line of 3 NNE-trending explosion craters north of the city of Chalchuapa, the highest of which is 1035-m-high Cerro Tablas.
