The name was given in honor of King Ferdinand II of Aragon, who sponsored the voyage of Columbus. Fernandina has an area of 642 square kilometres (248 sq mi) and a maximum altitude of 1,494 metres (4,902 ft). This is the youngest and westernmost island. In May 13, 2005, a new very eruptive process began on this island when an ash and water vapour cloud rose to a height of 7 kilometers (4.4 mi) and lava flows descended the slopes of the volcano on the way to the sea. Punta Espinosa is a narrow stretch of land where hundreds of Marine Iguanas gather largely on black lava rocks. The famous Flightless Cormorant inhabits this island and also Galápagos Penguins, Pelicans and Sea Lions are abundant. Different types of lava flows can be compared and the Mangrove Forests can be observed.
