El Abra

El Abra is an archaeological excavation site, located in the valley of the same name, east of the city of Zipaquirá, department Cundinamarca, Colombia; in the Altiplano Cundiboyacense, at an altitude of 2,570 m. This cave system is one of the first Human settlements in America, used by the Homo sapiens inhabitants of the late Pleistocene epoch.

Stratigraphy

The first research in the place was developed in 1967, and the stratigraphy of lithic instruments, bones and vegetal charcoal with radiocarbon dating established the date of the settlement in 12,400 BCE ± 160 years.

Archaeological Research

In 1960, the Indiana University collaborated in a deeper research. In 1970 the Netherlands Foundation for the Advancement of Tropical Research (NWO-WOTRO) discovered four new Pre-pottery sites and the analysis of lake sediments allowed a more accurate understanding of the original weather and flora.

Fúquene stadial

From 15,000 BCE to 12,500 BCE. It is characterized by a cold weather, flora typical of Páramo ecosystem, and stone tools.
