The small pyroclastic cone Cerro Chopo (also known by the religious names of Anunciación, Coronación, or Asunción) lies south of the main Guanacaste Range and north of the city of Canas. The 250-m-high basaltic pyroclastic cone was constructed over regional ignimbrites and andesitic lava flows. The crater is oriented to the NW and was the source of olivine-basaltic lava flows. Cerro Chopo was roughly estimated by Alvarado (2000) to be of late Pleistocene age (perhaps 40,000-10,000 years old). The interior of the cone, which lies along the well-traveled road from Canas to Tilarán, has been exposed by quarrying for road construction materials. Another small isolated cinder cone of similar age, Corobici, lies along the Río Corobici to the west.
