BLACKWATER RAFTING

n.

A sport that involves riding inner tubes on rivers that run through caves.

"In a typical black-water rafting session, the rafters settle onto their tubes, turns on their headlamps, grasp the legs of the person in front of them, and then ride the underground river as a group. (This linked chain method of rafting is known as 'eeling'.)"
