The cave system has the greatest proven depth potential in the world as proven by a dye trace from its main entrance to the resurgence 2547 meters lower. The current terminus of the main Chevé system is a large breakdown pile reached after diving through two sumps. It is just over 9 kilometers from the entrance, making it currently one of the most remote underground locations on earth. Due to the logistical difficulties of continuing exploration from this point, current expeditions are focusing on finding mid-way entrances that might provide a quicker route into the middle Chevé system.
