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.
Cordillera del Cóndor
The Cordillera del Cóndor (Condor mountain range) is a mountain range in the eastern Andes that is shared by and part of the international border between Ecuador and Peru.
The range extends approximately 150 km north to south and its maximum elevation reaches approximately 2,900m. The Río Santiago and Cenepa River flow along its eastern slopes on the Peruvian side. For over 160 years, the area of the border was in dispute, and sparked armed conflicts between the two countries in 1941, 1981 and 1995. After the border conflict of 1995, the two countries began diplomatic negotiations, resulting in the 1998 peace treaty that established the exact location of the international border.
