Granite Falls is almost a perfect reverse of House Rock with the bend coming on river right instead of left, rated an 8 with an 15 foot drop.  The approach is similar and the run is similar but with one major difference.  The location of the rocks at the mouth and submerged along the right wall creates massively exploding waves that appear at irregular and unpredicatable intervals off the wall.  We hit the rapid just fine when one of those rogue waves smashed into the boat, tossing Mark into the river at the top of the rapid.  He was ok but it was one scary ride as he essentially ran the entire rapid in his lifejacket.  Bill almost joined him, but Brian's quick thinking and highsiding on the right side stabilized the boat and we made it the rest of the way ok.
