The return dive through 220-meter-long Sump 2 with two 55-liter packs of equipment. Lead and rocks were used to ballast the packs so that they were approximately neutrally buoyant underwater.

Sump 4 has now been explored in two different tunnels to 170 meters and 350 meters penetration, respectively. The main tunnel averages 8 to 10 meters wide by 5 to 8 meters tall. It continues at 350 meters penetration and appears to be rising. The direction of the tunnel - almost due west towards Cueva Cheve - confused the early exploration efforts. It now promises a potentially quick connection to the main subterranean Cheve river.
