Ecuador
Ecuador's capital is Quito, which is in the province of Pichincha in the Sierra region. Its largest city is Guayaquil, in the Guayas Province. Cotopaxi, just south of Quito, is one of the world's highest active volcanoes. The top of Mount Chimborazo (6,268 m, or 20,560 ft, above sea level), Ecuador's tallest mountain, is the most distant point from the center of the Earth on the Earth's surface because of the ellipsoid shape of the planet.
Carihuairazo
Carihuairazo was climbed by Edward Whymper, the cousins Louis and Jean-Antoine Carrel, and Ecuadorians David Beltran and Francisco Campaña, during their 1880 Ecuador expedition. It is not entirely clear from Whymper's description, but some people believe that they climbed the "Mocha" (4,960m) and not the "Maxim" summit (5,018m). The first ascent of the "Maxim" summit is therefore attributed to Arturo Eichler, Horacio Lopez Uribe and Jean Morawiecki in 1951. Whymper and his companions ascended in cloudy conditions, believing the east peak (Mocha) to be the higher one. When the clouds cleared on their descent, Whymper said they could see they had climbed the west peak. It is likely that he meant the central summit, which is just west of Mocha.
