Cordillera Blanca

 

the highest mountain range in the Corsdillera Occidental of the Peruvian Andes. It is part of the interoceanic drainage divide between the Santa and Marafion river basins. About 180 km long, the range has 35 peaks over 6,000 m in elevation, the highest of which is Mount Huascaran (6,768 m). It is composed primarily of intrusive rock. The Cordillera Blanca is the largest glacial region not only of the tropical Andes but of the earth’s equatorial and subequatorial zones as well, with contemporary glaciation covering 1,000 sq km. Perennial snows begin at elevations of about 5,000 m. The slopes are mainly covered with dry mountain-steppe vegetation.
