The Colombian highlands consist of three parallel mountain ranges (Fig. 1)called respectively the eastern, central, and western cordillera of the Andes.A segment of the range that forms the backbone of the Isthmus of Panama alsoextends into Colombia, along the Pacific coast, as far southward as the mouthof the San Juan River.
These four mountain ranges furnish the key to the varying climaticconditions and vegetation of the country. The river valleys are hot and coveredwith dense tropical growth. This is also generally true of the coastal plain,although in the northern portion there are some fairly open stretches wherecattle are raised and even small districts where semi-arid conditions prevail.The population of this heavily wooded wet lowland depends almost entirely onriver transportation for all intercourse.
The elevated mountainous plateaus of the three ranges are more open and moregenerally cultivated; all traffic is by means of horses, mules, and the burro.The canoe and river-steamer transportation systems of the valleys are connectedwith the highland system of trails and roads by short cross trails and the fewshort railroads of the country. As these cross trails must pass through theintermediate foot-hill region, where the heavy rainfall reaches its maximum,they are exceedingly bad and the life of pack animals is short. The oildevelopment of the Magdalena River valley is in this intermediate region,between the river and the sierras, north of Bogota.
The predominant sedimentary formations in Colombia are those of Tertiary age.They form the floor of the Magdalena River valley and the coastal plain thatborders the Caribbean Sea: this is also true of the southern part of the narrowcoastal belt of the Pacific coast.
