Arguably most difficult at 4-5'. Above 5', things begin to wash out, though there are some BIG holes and waves.
The biggest drop on the Lower Yough. From the big eddy at the top on river left where Cucumber Run comes in, work your way staying mostly left through a rocky boulder garden. The current in the boulder garden will begin to move you to the right as you approach "Guide Rock" and the main drop. To the immediate right of "Guide Rock" is a tongue - try to stay as far left on this this tongue as possible (a last minute current off "Guide Rock" will try to push you to the right - don't let this happen). Take the drop on the tongue and keep paddling through some splashy waves. Eddy left. River racers take a line to the left of guide rock (it's faster) and there is a line that requires some aggressive paddling to the right as you approach "Guide Rock" to catch an right side eddy from which there's a rocky drop into the main current. At most levels, the tailwaves have some play potential. (At summertime levels this is not a good place to flip as there's a barely submerged rock that will clock ya upside the head if you invert without seriously tucking, and, at really low water, whether you tuck or not.) Between the high 3's and the high 4's the preferred line starts to shift to the right side of the main drop. At higher levels [above 6'] "Guide Rock" and the ledge form a huge hole from the left shore to the center of the river; the line is to stay right on the main current and punch the standing waves. Also [above 6'] the loop rapids run into each other, resulting in a wild ride from "Cucumber" down, with only a little break before "Railroad."
