Geography

The caldera is about 10 km across, and in places the walls tower 2000 m over the caldera floor. The highest point is the Roque de los Muchachos on the northern wall, at 2426 m altitude, which can be reached by road. The Cumbrecita is at a lower point in the south-eastern part of the caldera's rim. In the south-west, the caldera opens to the sea, through a riverbed called the Barranco de las Angustias. The Cumbre Nueva is a ridge that starts at the caldera and continues to the south. The caldera originated some 2 million years ago, with a massive

where he was taken to the Caldera de las Cañadas. He visited La Palma after he had been to Tenerife, and in his journal he makes it clear that he was able to distinguish between a caldera of volcanic origin and the erosional origins for the caldera Taburiente. Following his return to Germany he published his journal and he introduced the term ''caldera'' to the geological vocabulary. In the 1830s, the caldera provided inspiration for some art that combined a study of geology with botany, such as the work of Sabin Berthelot and Felix-Achille St. Aulaire.Met Museum New York, "A Memory of Caldera" by Felix-Achille St. Aulaire, online at http://www.metmuseum.org/art/collection/search/356782
