Alejandro Selkirk Island is the largest and most westerly island in Chile’s Juan Fernández Archipelago. Previously known as “Más Afuera,” it was renamed after 18th-century marooned sailor, Alexander Selkirk, who is thought to have inspired the title character in Daniel Defoe’s “Robinson Crusoe” novel. The island is densely wooded and mountainous, with tremendous coastal cliffs up to 1,000 meters (3,281 ft) high on its east coast.—-33.751111°, -80.783333°
