Drops about 18 feet total. Very clean for an 18 foot slide, but has an undercut rock at the bottom left side. Run down the center with a little right angle if possible to avoid the undercut rock. This would probably not be that difficult of a rapid if it were not for the what it factor.
Be aware that this is the last slide and only has a small pool before you will be running the 70 footer below. This would be a place where you would need saftey set at bottom to make sure no-one runs the big one.
