Stalactites
The underground river is pitch black. The front person in our canoe had a battery operated light that was swung around at the behest of the guide paddling the boat from the rear. He described the formations of stalactites and stalagmites.
The light wasn’t strong enough for pictures so I threw a flash on my camera which enabled me to capture a few of the underground formations. Most, however, were too distant to be photographed.
