82 22 na_thmb_lelost_photo Plane WreckPlane WreckExplorers and scientists have ventured to the region since the 1830s, traveling by boat and on foot. Now explorers and tourists alike visit the Lost World by plane. But the trip may be dangerous. Several plane wrecks, including this DC3, litter the tepuis landscape. Black CurassowBlack CurassowCurassows are the largest types of game birds called pigeon-toed fowls. These roosting birds whose meat is considered a delicacy are found in other parts of the world -- from Argentina to Texas. They are named for the island of Curaçao although none are found there. Spider MonkeySpider MonkeyAmidst the tropical forests of the tepuis are spider monkeys. These monkeys, found in forests throughout Central America, are known for their extreme agility in trees and rarely venture down to the jungle floor. Carrao RiverCarrao RiverSeveral rivers crisscross the Lost World's savanna -- many of which are only navigable during the rainy seasons. Travel via a dugout canoe on the Carrao river and you'll encounter giant otters as well as monkeys and birds living in the jungles on either side of the river. Seedeater BirdSeedeater BirdJust as the plants are peculiar to the tepuis, many birds are also unique species. They are, for the most part, seedeaters and nectar feeders who have adapted to this hostile environment and learned to forage for food anyway they can. StegolepisStegolepisPlants have adapted to the unique environment of the Lost World. Many are carniverous (see Eco Explorer, Florascope) while some have no permanent anchorage -- moving where flash floods take them. This stegolepis (Stegolepis guianensis) grows at the summit of Mount Roraima. River of GoldRiver of GoldExplorers and adventurers are drawn to the Lost World by its legendary rivers of gold. Jimmie Angel, who discovered Angel Falls, was actually in search of gold when he spotted the waterfall that now bears his name. This river of gold atop Auyantepui gets its color from plant tannins. Valley of the CrystalsValley of the CrystalsAtop Mount Roraima, quartz crystals sprout from the ground in profusion, giving rise to the legend that the Lost World has fields of diamonds. The layers of quartz are revealed when soft sandstone erodes. Sarisarinama SinkholeSarisarinama SinkholeExplorers traveling to the region via airplane discovered new worlds: sinkholes. Here a 1,000-foot hole in the Sarisarinama tepui contains an isolated forest with many unique species. Vulture RockVulture RockMillions of years of wind, sun, and rain have created rock sculptures. These black rocks, often covered with lichen and moss, take on the shape of dinosaurs, animals, and humans -- adding myth and mystery to the region. Autana CaveAutana CaveAutana tepui has caves whose tunnels pass through one side to the other. These caves were formed 3 billion years ago by an underground river system. One cave, formed entirely of quartz, measures 1,300 feet in length and 130 feet in height. Gran SabanaGran SabanaThe diverse terrain of the region includes the flat plateaus of the Gran Sabana as well as the towering tepuis. The origins of the savanna are unclear but some scientists say that it may have resulted from regular burning by indigenous inhabitants during prehistoric times. Angel FallsAngel FallsAt 3,212 feet Angel Falls is the world's highest waterfall. It pours from the rainforest-covered Auyantepuis and plunges into Devil Canyon. In the wet season (June to December) the falls are voluminous and spectacular. Mount RoraimaMount RoraimaThe Lost World's tabletop mountains or "tepuis" tower over the jungle and savanna grasslands. Mount Roraima, which means "the great, ever fruitful mother of streams" is the tallest rock formation in the region.
