Andean natural region
The Andes mountains form the most populated region of Colombia and contain the majority of the country's urban centers. They were also the location of the most significant pre-Columbian indigenous settlements. Beyond the Colombian Massif in the south-western departments of Cauca and Nariño, the Colombian Andes divide into three branches known as "cordilleras" (from the Spanish for "mountain range"): the West Andes run adjacent to the Pacific coast and is home to the city of Cali. The Central Andes run up the center of the country between the Cauca and Magdalena river valleys (to the west and east respectively) and includes the cities of Medellín, Manizales and Pereira. The East Andes extend northeast towards the Guajira Peninsula, and includes the cities of Bogotá, Bucaramanga and Cúcuta.
List of Pyrenean three-thousanders
All the peaks in this list are in Spain (59 peaks) or France (26 peaks), or delimit the border between the two countries (45). The two highest major mountains and their subsidiary summits (Aneto and Posets - Zone 7 and 9) are entirely in Spain, together with the Besiberri peaks (zone 10) while Pic Long and surrounding mountains (zone 5) are entirely in France. Most of the other mountains lie on or close to the border. The small country of Andorra is located in the eastern portion of the Pyrenees and is surrounded by Spain and France; its highest mountain – Coma Pedrosa at – falls below the 3,000-metre threshold. The mountains are listed by height within each of the 11 zones.
