Probably one on the most dangerous passage in this circuit. It's a large rock that forms a natural bridge over a deep crevice. The rock is bent and slippery, so we cross it using a rope. If the rope was to break or if we let go the rope, we would fall in a the deep hole under the rock and likely die. No room for mistake at this one. Also, if your feet slip on the rock, you could hit it with your head and get knocked out. So the best way it to bend backward to put the body perpendicular to the rock, which means that most your weight is on the rope. You just have to pray that the rope and its anchors are strong, and to make sure you hold the rope very tight.
This is our guide, Roland, showing us the technique.

The Clearwater System is believed to be the largest interconnected cave system in the world by volume and the 9th longest cave in the world at 189 Km (as of 2011). For more photos, information and cave map, view my Clearwater cave photo series.
