Blackwater, North Fork - Rt. 219 to confluence with Blackwater River (WV)
Below Gluteal Mash, there is a good rock garden best run down the left, over a few small drops. Catch the next eddy on the left and get out and scout. The very next rapid is called The World's Ugliest Rapid. It is not super difficult but the whole right bank is undercut (where most of the water is). The idea is to boof far left off a 2-foot ledge, land and immediately boof left off a 4-foot ledge. These two boofs keep you away from the undercuts. If you blow the first boof, the water will want to pull you to the right and make it difficult to avoid the undercuts.
