need to be on top of this one:

Chimborazo is an extinct volcano located in the Western Cordillera, 150 km (95 miles) southwest of Quito. For this climb you need ice-climbing equipment, excellent physical condition and lots of stamina. Climbers must also acclimatize their bodies to the high altitude conditions before attempting to summit Chimborazo. Most of the time, it is not a difficult climb but there are periods when hard ice conditions make it very challenging.

The sight of Chimborazo (6,310 m / 20,702 ft), the tallest peak in Ecuador, is among the most impressive in all of the Andes. Since the Earth bulges near the equator, this snowcapped giant is not only the highest mountain in Ecuador, but also the highest in the world if measured from the core of the Earth outward to the peak.
