Geography
Robinson Crusoe Island has a mountainous and undulating terrain, formed by ancient lava flows which have built up from numerous volcanic episodes. The highest point on the island is 916 m (3,005 ft) above sea level at El Yunque. Intense erosion has resulted in the formation of steep valleys and ridges. A narrow peninsula is formed in the southwestern part of the island called Cordón Escarpado. The island of Santa Clara is located 1.5 km (0.9 mi) off the southwest coast.
Robinson Crusoe Island lies to the west of the boundary between the Nazca Plate and the South American Plate, and rose from the ocean 3.8 – 4.2 million years ago. A volcanic eruption on the island was reported in 1743 from El Yunque, but this event is uncertain. On the February 20, 1835, a day-long eruption began from a submarine vent 1.6 kilometres (1.0 mi) north of Punta Bacalao. The event was quite small, only a Volcanic Explosivity Index 1 eruption, but it produced explosions and flames that lit up the island, as well as tsunamis.

Famous quotes containing the word geography:
“At present cats have more purchasing power and influence than the poor of this planet. Accidents of geography and colonial history should no longer determine who gets the fish.”
—Derek Wall (b. 1965)
“Where the heart is, there the muses, there the gods sojourn, and not in any geography of fame. Massachusetts, Connecticut River, and Boston Bay, you think paltry places, and the ear loves names of foreign and classic topography. But here we are; and, if we tarry a little, we may come to learn that here is best. See to it, only, that thyself is here;—and art and nature, hope and fate, friends, angels, and the Supreme Being, shall not absent from the chamber where thou sittest.”
—Ralph Waldo Emerson (1803–1882)
“The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
—Willard Van Orman Quine (b. 1908)
