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.
Chimborazo
Under clear conditions, the summit of Chimborazo can be seen from the coastal city Guayaquil, nearly 140 km away. The nearest cities are Riobamba (~30 km to the southeast), Ambato (~30 km to the northeast) and Guaranda (~25 km to the southwest). Chimborazo is surrounded by the "Reserva de Produccion Faunistica Chimborazo", which forms a protected ecosystem to preserve the habitat for the Andes native camelids of vicuña, llama and alpaca.
Chimborazo is at the main end of the Ecuadorian Volcanic Arc, north west of the town of Riobamba. Chimborazo is in la Avenida de los Volcanes (the Avenue of Volcanoes) west of the Sanancajas mountain chain. Carihuairazo, Tungurahua, Tulabug, and El Altar are all mountains that neighbor Chimborazo. The closest mountain peak, Carihuairazo, is from Chimborazo. There are many microclimates near Chimborazo, varying from desert in the Arenal to the humid mountains in the Abraspungo valley.
