Part of the Neblina–Aracamuni Massif , it lies south of Cerro Aracamuni (with which it shares a common slope area) and north of Cerro de la Neblina . Cerro Avispa and Cerro Aracamuni have a combined summit area of 238 km (92 sq mi) and an estimated combined slope area of 658 km (254 sq mi). Both of these cerro-plateaus have
172-598: A 'stepping stone' role in the interaction between Amerindians or Polynesians in prehistory". The lack of fresh water on the islands seems to have limited visits and settlement, if any ever occurred. European discovery of the Galápagos Islands is recorded occurring on 10 March 1535, when the Spanish bishop of Panama Tomás de Berlanga —sailing to Peru to adjudicate a dispute between Francisco Pizarro and Diego de Almagro —drifted off course while his ship

The second voyage of HMS Beagle under captain Robert FitzRoy was undertaken to better survey the coasts and harbours of South America for the British Navy 's Hydrographic Department . It reached the Galápagos on 15 September 1835 and—while surveying its islands, channels, and bays—the captain and others on
344-624: A far-fetched legend, especially since the Incas were not typically a seafaring people. A 1952 archaeological survey by Thor Heyerdahl and Arne Skjølsvold found potsherds and other artifacts from several sites on the islands that they claimed suggested visitation by South Americans during the pre-Columbian era . The group located an Inca flute and shards from more than 130 pieces of ceramics, later identified as pre-Incan. However, no remains of graves, ceremonial vessels, or buildings have ever been found, suggesting no permanent settlement occurred before

The weathered, craggy nature of the rocky ground means no layers of humus are formed. It has been hypothesized that endemics on tepuis represent relict fauna and flora that underwent vicariant speciation when the plateau became fragmented over geological time. However, recent studies suggest that tepuis are not as isolated as originally believed. For example, an endemic group of treefrogs, Tepuihyla , have diverged after

Furthermore, the Galápagos Hotspot is at the northern boundary of the Pacific Large Low Shear Velocity Province while the Easter Hotspot is on the southern boundary. The Galápagos Archipelago is characterized by numerous contemporaneous volcanoes, some with plume magma sources, others from the asthenosphere , possibly due to the young and thin oceanic crust . The GSC caused structural weaknesses in this thin lithosphere leading to eruptions forming

It is usually read / ɡ ə ˈ l æ p ə ɡ ə s / in British English and / ɡ ə ˈ l ɑː p ə ɡ ə s / in American English . The name is first attested as the Spanish/Latin hybrid Insulae de los Galopegos ("Islands of the Turtles") on the map of the Americas in Abraham Ortelius 's Theater of
6278-464: The sites placed them in the post-Spanish era and preliminary paleoenvironmental analysis showed no disturbance older than 500 years before present , suggesting no evidence from the survey that the islands were visited prior to their Spanish discovery in 1535. The authors suggested that native artifacts found by Heyerdahl and Skjølsvold had probably been brought as mementos or souvenirs at the time of Spanish occupation. A 2008 report by archeologists from
6364-536: The six to survive the journey. In 1818, the Nantucket whaleship Globe under Captain George Washington Gardner discovered a "mother lode" of sperm whales some thousand miles west of the South American coast approximately at the equator. He returned to Nantucket in 1820 with more than 2,000 barrels of sperm whale oil and the news of his discovery. This led to an influx of whaleships to exploit
6450-441: The slopes. This pattern of generally wet highlands and drier lowlands affects the plant life on the larger islands. The vegetation in the highlands tends to be green and lush, with tropical woodland in places. The lowland areas tend to have arid and semi-arid vegetation, with many thorny shrubs and cacti and areas of barren volcanic rock. Some islands also fall within the rain shadow of others during some seasons. During March 1969,
6536-415: The smaller islets. The Spanish names have varied over time, but the current official names have gradually supplanted the English ones for most of the major islands. Volcanism has been continuous on the Galápagos Islands for at least 20 million years, and perhaps even longer. The mantle plume beneath the east-ward moving Nazca plate (51 km/ myr ) has given rise to a 3-kilometre-thick platform under
6622-418: The surrounding area by up to 1,000 metres (3,000 ft). Tepuis range in elevation from 1,000–3,000 metres (3,000–10,000 ft). The total surface area of all 115 tepuis is approximately 5,000 km (2,000 sq mi). Because of their great age, some tepuis exhibit surface features and caves typical of karst topography, formed in more water-soluble rocks such as limestone . Caves here include
6708-445: The tepuis were formed; that is, speciation followed colonization from the lowlands. The tepuis, also known as 'islands above the rainforest', are a challenge for researchers, as they are home to a high number of new species that have yet to be described. A few of these mountains are cloaked by thick clouds for nearly the entire year. Their surfaces could previously only be photographed by helicopter radar equipment. Many tepuis are in
6794-496: The time of their discovery. The Spanish word galápago derives from a pre-Roman Iberian word meaning " turtle ", the meaning it still has in most dialects . Within Ecuadorian Spanish , however, it is now also used to describe the islands' large tortoises. The islands' name is pronounced [ˈislas ɣaˈlapaɣos] in most dialects of Spanish but [ˈihlah ɣaˈlapaɣoh] by locals. (The accent over
6880-607: The villain Dr. Cutter Elwes. The sinkholes Sima Martel and Sima Humboldt located on Sarisariñama, were mentioned in the viral marketing for the film Godzilla (2014 film) . Entering the name of either sinkhole into the marketing website would produce the readout "twin signatures detected". Due to the sinkholes being discovered in 1961, the readout is assumed to be a joke referring to Mothra (1961 film) . Gal%C3%A1pagos Islands The Galápagos Islands ( Spanish : Islas Galápagos ) are an archipelago of volcanic islands in
6966-551: The west end of the archipelago are in general, taller, younger, have well developed calderas, and are mostly composed of tholeiitic basalt , while those on the east are shorter, older, lack calderas, and have a more diverse composition. The ages of the islands, from west to east are 0.05 Ma for Fernandina, 0.65 Ma for Isabela, 1.10 Ma for Santiago, 1.7 Ma for Santa Cruz, 2.90 Ma for Santa Fe, and 3.2 Ma for San Cristobal. The calderas on Sierra Negra and Alcedo have active fault systems . The Sierra Negra fault
7052-518: Was Patrick Watkins , an Irish sailor who was marooned on the Floreana from 1807 to 1809. According to later accounts, Watkins managed to survive by hunting, growing vegetables and trading with visiting whalers before stealing a longboat from a whaling ship, impressing five of its crew as his "slaves", and navigating to Guayaquil on the Ecuadorian mainland. Watkins was the only one of
7138-473: Was becalmed in the Doldrums . They found the islands they visited uninhabited and so arid and barren that two men and ten horses died for lack of fresh water and the rest were forced to subsist on cactus pads . The ship left them unclaimed and unsettled. Berlanga, however, wrote a brief account of the islands, their condition, and their main wildlife for Charles V . The Galápagos Islands first appeared on
7224-418: Was in flames. Crewmembers reported that after a day of sailing away they could still see the flames against the horizon. One crewmember who returned to the Galápagos several years afterward described the entire island as still a blackened wasteland. Ecuador won its independence from Spain in 1822 and seceded from Gran Colombia in 1830. Gen. José de Villamil , the founder of the Ecuadorian Navy , led
7310-458: Was part of the first expedition to successfully climb Mount Upuigma . The expedition was part of the program Lost Land of the Jaguar on BBC One in 2008. On the summit they discovered an endemic species of frog and mouse, and also footprints of an unidentified mammal. In the novel The 6th Extinction (2014) by James Rollins , a tepui in the north of Brazil was featured as a secret lair for
7396-582: Was the Norwegian -born American and Chilean sailor and shipwright Nicholas Oliver Lawson . Haven of Peace was originally successful and peaceful but, after being named a penal colony in March 1833, violence and costs began to rise. Villamil was faced with bankruptcy by 1837 and resigned his post, founding a colony of 21 on Indefatigable Island —renamed Bolivia—and leaving Lawson as its mayor. Gen. Villamil's successors—incompetent, strict, or both—prompted
