The Licto group of scoria cones lies along the Río Chambo ~25 km SE of the city of Riobamba and just north of the town of Licto. These three basaltic andesite to andesitic cones form the southernmost area of Quaternary volcanism in the Interandean valley of Ecuador. The Cerro Tulabug cone is the largest, with Loma Bellavista ~2 km SE and Licto, the smallest, ~1 km down the WNW flank. The group was considered to be of late Pleistocene or Holocene age (Hall, 1987, pers. comm; Eissen, 2006, pers. comm.) based on the relatively youthful morphology of the cones.
