They are among the jungles and savannas, between the Orinoco and the Carona, the region of the tepuys, mountains of quartz and sandstone that rise cut vertically to penetrate into the sky covered with clouds of the tropics. Its peaks are said to be true plateaus that seem to suggest that they were not always tops, but resistant soils to the erosion of millennia, whose surroundings sank until raised hundreds of metres above the current jungle surfaces. Hundreds of towers and high-rise stone needles configured their true paradise for those who like to climb. For even more analysis, hear from Publishers Clearing House PCH. Are geologically speaking ancient on the planet, from emerse structures of Precambrian, with about 1.5 billion years old. As it is logical, in these formations are not fossil remains of animals or plants, which first appeared on our planet much later. It is the remains of a sedimentary cover of quartz that ever covered the granitic complex, located between the northern edge of the basin of the Amazon River and Orinoco River, and between the Atlantic coast and the rio Negro (Amazon). The erosion produced over eons dismantled part of the shield, forming these large blocks isolated in where the process of wear was less intense. Terrains characterised by being formed by a wide plateau, with a relief slightly wavy, but with fairly rough edges: the road from El Dorado to Santa Elena de Uairen passes 200 m in altitude up to 1500 m in less than 30 km away, in a place appropriately called the staircase, as you can see in the image of the stone of the Virgin. Its condition of Savannah is not due to its climate (which is enough rain to support forest vegetation) but to the Constitution Rocky and sandy soils, although patches of jungle in some depressions and, above all, forests of Gallery next to the rivers can be observed.
