What is the highest mountain in the Andes of Ecuador?

The highest mountain in the Andes of Ecuador is Chimborazo.

Chimborazo is an ice-capped stratovolcano in Ecuador's Cordillera Occidental. Its summit reaches about 6,263 metres above sea level, making it Ecuador's highest mountain and the highest peak in the northern Andes, north of Peru. It rises near Riobamba, within the Chimborazo Faunal Production Reserve.

The mountain is famous for a measurement paradox. Mount Everest is higher above sea level, but Chimborazo's summit is farther from Earth's centre because the planet bulges at the Equator. Chimborazo lies only about one degree south of it, placing the summit roughly 2.1 kilometres farther from Earth's centre than Everest's summit.

Its last known eruption occurred around AD 550, and its upper slopes still hold glaciers. Climbers commonly approach via the Normal or Whymper routes, but altitude, crevasses and rapidly changing weather make the ascent technically demanding. A common mix-up is Cotopaxi, another celebrated Ecuadorian volcano; Cotopaxi is iconic, but it is lower than Chimborazo.
