DescriptionThis is Section 2 of Rock Run in the Washington D.C. Area. This run passes below the C&O canal and a busy road in two 100yd culverts. These culverts were built in 1963. The section of the river above this passes by a heavily guarded military research facility. If you're wandering around that area or taking pictures you're likely to get some unwanted attention from the military police. According to Steve Ettinger:"At it's end the left culvert drops four feet over a concrete lip and then hits a natural rock slide where it slides 6ft at about 60 degrees into a small pool. This looks like class 5.0 and the right culvert looks even tougher. Ten yards later there is a 5 foot natural ledge."I have wanted to run this drop for a while and I've gotten skunked on it in the past. We got lucky because we got there in the middle of a huge rain and there was enough water. I'd rate the left culvert as class IV+ because the natural ledge below the lip complicates the boof and the current is pushing hard into the rock wall on river-left just below the drop, making it likely that someone could get stuck if they flipped at the bottom. The rocks that form the second drop are very jagged formations and the center and right side don't look friendly. Luckily there is a good line on the far left side of that drop. With a little less water than we had in this video that bottom drop would probably be a lot harder. Big Thanks to Brian Decicco for coming through in the clutch to set safety and capture some of the video used in this edit!
