BackgroundCerro Tilarán, also known as Cerro Tovar, is a small andesitic shield volcano that lies at the NW end of the Tilarán Range west of Lake Arenal. The 634-m-high Tilarán volcano rises immediately SW of the town of the same name. The morphologically youthful Tilarán cone is overlain only by tephra deposits from Arenal (maximum age about 7000 years), however an Ar-Ar date of 1 million years was obtained (Alvarado, 2000) and the volcano is of Pleistocene age (Alvarado 2005, pers. comm.). The Tilarán Range, which lies to the west of the main volcanic chain, is a fault-bounded tectonic block of Miocene-Pleistocene andesitic rocks of the Monteverde formation. The densely forested range is renowned for its abundant exotic birds and wildlife.
