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.
Machachi
Machachi is located to the south of the capital of Ecuador, Quito. It is a city surrounded by the volcanos Atacazo, Corazon, Rumiñahui, Illinizas Peaks, Viudita Hill, Pasochoa, and Sincholagua, and owns part of the Cotopaxi volcano, a great active volcano which measures 5,897 m (19,347 ft) in altitude. In fact, the valley owns eight volcanoes inside, one the reasons Alexander von Humboldt named the region "Avenue of Volcanoes".
