Andean condor
The Andean condor is found in South America in the Andes, including the Santa Marta Mountains. In the north, its range begins in Venezuela and Colombia, where it is extremely rare, then continues south along the Andes in Ecuador, Peru, and Chile, through Bolivia and western Argentina to the Tierra del Fuego. In the early 19th century, the Andean condor bred from western Venezuela to Tierra del Fuego, along the entire chain of the Andes, but its range has been greatly reduced due to human activity. Its habitat is mainly composed of open grasslands and alpine areas up to in elevation. It prefers relatively open, non-forested areas which allow it to spot carrion from the air, such as the páramo or rocky, mountainous areas in general. It occasionally ranges to lowlands in eastern Bolivia and southwestern Brazil, descends to lowland desert areas in Chile and Peru, and is found over southern-beech forests in Patagonia.
Eastern Frontal Fault System
The long Afiladores Fault runs through a geographic area of the Andes where the Central and Eastern Ranges merge into a single range known as the "Cordillera Centro-Oriental de Colombia". The fault offsets Precambrian gneisses and schists, metamorphic Paleozoic rocks, Mesozoic granitic rocks, and Tertiary sedimentary deposits. The fault extends south into the Republic of Ecuador and probably connects with the Chingual Fault.
