Colca Canyon Colca Canyon is a canyon of the Colca River in southern Peru, located about 160 kilometres (99 mi) northwest of Arequipa. It is Peru's third most-visited tourist destination with about 120,000 visitors annually.[1] With a depth of 3,270 metres (10,730 ft),[2] it is one of the deepest in the world. The Colca Valley is a colorful Andean valley with pre-Inca roots, and towns founded in Spanish colonial times, still inhabited by people of the Collagua and the Cabana cultures. The local people maintain their ancestral traditions and continue to cultivate the pre-Inca stepped terraces.
Río de la Plata Basin The Río de la Plata basin (Spanish: Cuenca del Plata, Portuguese: Bacia do Prata), more often called the River Plate basin in scholarly writings[1], sometimes called the Platine basin[2] or Platine region,[3] is the 3,170,000-square-kilometre (1,220,000 sq mi)[4] hydrographical area in South America that drains to the Río de la Plata. It includes areas of southeastern Bolivia, southern and central Brazil, the entire country of Paraguay, most of Uruguay, and northern Argentina. Making up about one fourth of the continent's surface, it is the second largest drainage basin in South America (after the Amazon basin) and one of the largest in the world.[5]
