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.
Mount Chirripó
Mount Chirripó is the highest mountain in Costa Rica with an elevation of 3,821 meters (12,536 feet). It is located in Chirripó National Park and is noted for its ecological wealth. The mountain was named "Chirripo," meaning "land of eternal waters", by native Americans because there are many lakes and streams around the mountain. The high peaks in Chirripó National Park and La Amistad International Park host important areas of Talamancan montane forest and Costa Rican Páramo with high endemism and an extremely high biodiversity. The peaks of these mountains constitute sky islands for many species of plants and animals. Snow has not fallen on the peak in the past 100 years or so, according to the University of Costa Rica, but hail is sometimes reported.
