| staircase |
When used anywhere near Pennsylvania, usually refers to the section of the Shenandoah River at Harper's Ferry. The Staircase itself is about a mile of the river, just about its confluence with the Potomac, which contains dozens of diagonal ledges ranging from a few inches to several feet high. It's class II-III at most levels, but becomes significantly harder at high flows due to the continuous nature of the rapids.
