Potomac

This is the infamous Room of Doom. Most of the current pushes against the rock wall just to the left of this feature, making a whirlpool on the right. Really not a good place to be at any level.
This is the eddy halfway into the main LF drop on the VA side. It's definitely where you want to be to avoid Cleaver. From here it's fighting the squirrely current to avoid the Room of Doom.
For those that don't want to run the usual eddy turn VA line, this is a sneak route of sorts. Just watch for rocks on either side, especially the left.
