Cerro el Hoyo lies at the SE end of a subsidiary NW-SE-trending chain of pyroclastic cones of the Lake Yojoa volcanic field about 2 km NE of the lakeshore. The cones are surrounded by lava fields that are partially tholeiitic in composition, but mostly consist of trachytes, trachybasalts, and trachyandesites with large phenocrysts of sanadine and anorthoclase.
