The Cordillera Oriental (English: Eastern Ranges) is the widest of the three branches of the Colombian Andes. The range extends from south to north, dividing from the Colombian Massif in Huila Department to Norte de Santander Department where it splits into the Serran�a del Perij� and the Cordillera de M�rida in Venezuelan Andes. The highest peak is Ritacuba Blanco at 5,410 m (17,750 ft) in the Sierra Nevada del Cocuy.

Geography

The western part of the Cordillera Oriental belongs to the Magdalena River basin, while the eastern part includes the river basins of the Amazon River, Orinoco River, and Catatumbo River. Within it, the Altiplano Cundiboyacense and the Sierra Nevada del Cocuy (with the only snowy peaks in this mountain range) stand out. The mountain range contains the most p�ramos in the world.^{[citation needed]}
