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.
Pichincha (volcano)
Pichincha is an active stratovolcano in the country of Ecuador, whose capital Quito wraps around its eastern slopes. The two highest peaks of the mountain are Wawa Pichincha (Kichwa "wawa" child, baby / small, Hispanicized spelling "Guagua Pichincha") () and Ruku Pichincha (Kichwa "ruku" old person, Hispanicized "Rucu Pichincha") (). The active caldera is in Wawa Pichincha on the western side of the mountain.
