Tuco, Mountain peak in Cordillera Blanca, Peru
Tuco is a mountain peak in the Cordillera Blanca range, standing at 5,479 meters and positioned between Challhua and Pastoruri peaks in the northwestern central Andes. The mountain features steep slopes and glaciated sections typical of this alpine region.
The mountain was first successfully climbed in 1963 when mountaineers reached the summit via the northwest slopes. This expedition marked the beginning of the mountain's modern climbing history in the region.
The name comes from the Quechua language, where 'tuku' means owl and reflects the indigenous traditions of the Ancash region. This linguistic connection shows how deeply rooted the mountain is in local culture.
Altitude acclimatization is essential since oxygen levels drop significantly above 4,000 meters in this part of the Andes. Visitors should allow time to adjust gradually and ascend slowly to avoid altitude sickness.
A mountain stream originating from the peak feeds the lakes Aguashcocha and Conococha, forming the source of the Santa River. This water system links the high peaks of the Cordillera Blanca to the river valleys below.
