Here clouds are banked up on the east side, snow covers all higher slopes and mountain peaks, and glaciers occupy lower slopes. This prominent but short mountain range (25 kilometers in length) boasts twenty peaks of remarkable steepness and ridge sharpness.

Although only 100 kilometers from the coastline, six of the peaks reach above 6,000 meters (more than 19,500 feet), the highest of which is Nevado Yerupaja, Peru’s second highest peak, variously estimated as 6,617 and 6,635 meters high. Generally considered the most spectacular peak in South America, Yerupaja is so steep that it has seldom been climbed.

The best climbing approach is from the southwest, the face seen in this view. Yerupaja is locally known as El Carnicero (The Butcher) because of its blade-like ridges, features typical of mountains that have been heavily eroded by glacial ice.
