The creek is split into a right or left channel by a jumble of boulders in the center.  The left entrance requires a sketchy move against an undercut in the cliff wall at the entrance.  The right line has less water but is relatively clean.  We all ran left, but I gave it a careless scout and hit the 10 foot horizon line in the wrong place.  Unable get a proper boof, I went completely vertical and pitoned an underwater rock hard.  Fortunately my nose caved in and my bulkhead did its job to soften the blow.  Even though this drop is fairly straightforward, I learned to always scout carefully.
