Finally, about 2 million years ago, waters withdrew permanently. This resulted in the canyon that we see today.Ībout 4 million years ago, the shallow sea began to subside, as the limestone deposits emerged. At the time the Amazon flowed from south to north, originating in Brazil and forming a large delta in present-day Colombia.Īs the Central Andean mountain range emerged in Colombia, the limestone sediments that were deposited during the Devonian Period were transformed into marble crystals that were gradually exposed and sculpted by Rio Claro’s waters. The Rio Claro area formed part of a large shallow-sea that received sediments deposited by the Amazon River. The formation of Rio Claro’s watershed, has its origins in sedimentary deposits from the Devonian Period (419-358 million years ago). The karst formations include deep caves, stalactites, stalagmites, rock ripples and ladders. And the sieve-like topography provides striking artistic evidence of 6 million years of hydropower. It is literally a marble canyon with a river running through it.



The reserve sits atop the remnants of a shallow sea and coral reefs. It is located about 94 miles (152 km) southeast of Medellín on the Medellín – Bogotá highway.
