Lethe, the river of forgetfulness of the five rivers of Hades. If you're climbing this route you may have forgotten that there's better routes very nearby. That said, its not a bad route, just not much to it. Climb the slab and overhang left of Evelyn, and follow the easy crack from the ledge to the top.

I don't feel this is a 5.7 but closer to a 5.5 which is rare for the lake. It was on ok climb. The belay station is on a slope so make sure you keep up with rope management. Leading it wouldn't be too bad because there are trees you can wrap off on and a flaring crack you could throw some bigger nuts in. I'll be leading this one in April when I get back for a beer festival. Beautiful rock up there.
