Tuco, Mountain peak in Cordillera Blanca, Peru

Tuco is a mountain in the Cordillera Blanca whose summit reaches 5,479 m, one of the southernmost snow-capped peaks of the range. It lies in the Áncash Region, on the border of the Bolognesi and Recuay provinces, northeast of Caullaraju and between Challhua to the west and Pastoruri to the east. Its broad, rounded summit is capped by a snowfield broken by dark rock, with bare brown and grey rock descending into steep ridges and gullies below the snowline.

Tuco lies at the southeastern end of the Cordillera Blanca, on the border of the Aquia District in Bolognesi Province and the Catac District in Recuay Province, Ancash. Raju Cutac, further south, is the only Cordillera Blanca peak beyond it. Its summit is given as 5,300 m in some sources and 5,479 m in others; the Quechua name Tuco may derive from tuku, owl.
