Valle del Cauca Department
Summary
Valle del Cauca, or Cauca Valley (ˈbaʎe ðel ˈkawka), is a department in western Colombia abutting the Pacific Ocean. Its capital is Santiago de Cali. Other cities such as Buenaventura, Buga, Cartago, Palmira and Tuluá have great economical, political, social and cultural influence on the department's life. Valle del Cauca has the largest number of independent (i.e., nonmetropolitan) towns with over 100,000 inhabitants in the country, counting six within its borders. Buenaventura has the largest and busiest seaport in Colombia, moving about 8,500,000 tons of merchandise annually.
The department of Valle del Cauca is located in the western part of the country, between 3° 5′ N and 5° 1′ N latitude and 75° 42′ W and 77° 33′ W longitude. It borders the departments of Risaralda and Quindío to the north, Cauca to the south, Tolima to the east, and Chocó and the Pacific Ocean to the west. The valley is geographically bounded by the Cordillera Central and Occidental and is watered by numerous rivers that empty into the Cauca River. The department is divided into four zones: the Pacific Fringe, which is humid and mostly jungle; the western mountain range, also humid and full of jungle, heavily deforested because of the paper industry; the Andean valley of the Cauca River, whose surrounding lands are the most fertile in the country; and the western ridge of the Cordillera Central. Valle del Cauca also administers Malpelo Island in the Pacific.
Palynological analyses performed by experts have determined that during the Superior Pleistocene some 40,000–10,500 years ago, the valleys of El Dorado and Alto Calima had Andean forests and sub-Andean vegetation. The discovery of projectiles indicated that there were communities of hunter-gatherers at the end of the Pleistocene and the beginning of the Holocene. The extinction of the Pleistocenic megafauna in the beginning of the Holocene forced humans to adapt to their new environment, becoming hunter-gatherers.
