Mariñaqui, Laguna
"Volcán Laguna Mariñaqui is a minor volcanic center that lies SSE of Copahué volcano and ENE of Tolguaca volcano. It consists of two craters of Holocene age (González-Ferrán, 1995) 2 km apart along a NE-trending fault that produced andesitic pyroclastic material and lava flows with columnar jointing. Cerro Chapulul is a 2143-m-high Holocene cinder cone in this area of the Malleco province of central Chile (Moreno 1985, pers. comm.). The cone occupies a plateau ranging from 2000-2300 m in altitude."  -Smithsonian Volcano Archive
