Cordillera Negra

The Cordillera Negra (Spanish for "black range") is part of the Cordillera Occidental, one of three mountain ranges in the Andes of west central Peru. It is almost entirely located within the Ancash Region.

The range extends over an area about 230 km long and 25–40 km wide, stretching in a NNW-SSE direction parallel to the Pacific coast, its ridge is about 60 km from the coastline. It is part of the Andes mountain range which inland borders on the Costa, the narrow strip of coastal deserts along the South American coast. In the north and east the range is bordered by the Santa River which crosses the coastal ridge at 8° 45' S and runs parallel to the Cordillera Negra for almost all its length. In the south the range is bordered by the Patiwillka River at 10° 30'. In the central part of the range near Huaráz, Casma River breaks through the ridge of the range.

The Cordillera Negra has rocky peaks with very little winter snowfall. The gullies of the Cordillera Negra are gloomy and dark. Most of them are dry or their flow is scarce.
