Cerro Sarisariñama Located in the remote Venezuelan wilderness, hundreds of miles removed from the closest roads, is a Tepui, or a tabletop mountain. This mountain is home to a vast array of plant and animal species, but is renowned among the scientific community for its four giant sinkholes. The largest of these sinkholes, called Sima Humboldt, is over 350 meters wide and 315 meters deep. It is suspected that the sinkholes were shaped over time by the erosional forces of groundwater as it percolated downwards.
