A team of researchers recently embarked on a research expedition to the Tropical Andes of Colombia to study the massive Cauca River canyon. The team’s objective was to determine the age of formation of the Cauca River canyon and then compare that with known tectonic and climatic processes that happened in the region during the past 10 million years to figure out what caused its incision. The team concluded that erosion in the Cauca River canyon was driven by tectonic processes.
