A final view of visitors on the raft that floats over Kitch-iti-ki-pi as they gaze down through the transparent waters to the churning sand shapes forming constantly on the bottom. There is a submerged viewing port in the center of the raft all the visitors are gathered around which allows viewing without reflections. The raft itself is moved by a cable which the riders operate themselves.
