It's a rapid with one single drop. It's not very high, but has a lot of water flowing over it, with a nasty stopper at the bottom. I would not call it a waterfall.
It's notoriously dangerous, having killed several people (at least one of who's body was never recovered).
A lot of rafters say that even though it looks perfectly raftable nobody should attempt to raft it, except at high water levels (when it's not very noticeable, apparently). It didn't look at all raftable to me! We all portaged (walked/carried) around it. It's the last real rapid on the Franklin.
I don't have any photos of it, unfortunately - my camera batteries were flat by then, and my mate didn't send me a copy of the one he took.
PS. It is similar in drop height and water volume to the Pig Trough rapid, of which I have two photos on
this blog page. Big fall is more uniform with less rocks visible amongst the rapid, and probably a slightly higher drop and slightly narrower width of river.
