"Corner" rapid

AKA 'Stoney Run' rapid.  The river makes a hard right hand turn against a concrete wall on river left that contains a culvert for Stoney Run and which supports the road (MD 135) and the railroad siding that connects warehouses in Luke, MD to the B&O mainline at 21st bridge.  Set right angle to make the right turn, then there are a couple of ledges generally run in the center.  Class II at 1,000 cfs or lower; might be higher classed at higher levels.
