The terrific upper half is a bolted crack, but I'm not complaining. Start in the alcove to the right of the giant boulder, as for Adventure Kayak and River Dance. Up & right easily on the slab (R of RD) and follow a vertical face to a roof. The roof (crux) is wild, pumpy and complex for the legs/feet. (Note, there is a tempting and large wedged block midway through this passage which moves when gently pulled from some directions.) Above the roof, gain a good rest then follow an interesting 5.10 handcrack most of the rest of the way to the anchors. Use long slings on the 6th and 7th bolts to avoid rope drag.
Felt pretty solid in the grade, on a par w/ Hey Good Looking at Wall of the '90s.
Route 13 in the beta photo. This is the pitch described by Josh Finklestein under the comments for Slacker.
I've moved my comment to its proper location. This is the route that begins from the first belay bolts right of the AKT belay and trends generally right, pulling a roof to gain a rest at a chockstone followed by a pumpy jam crack. It's not to be missed--one of the best 5.11s in Clear Creek, on par with Curvaceous at Wall of the '90s but certainly harder. Beautiful rock, interesting movement, and spectacular position on the upper wall. Probably my favorite route on the River Wall, and there are some very fine routes there.
If you're a decent crack climber, the upper section will not feel that difficult. Beware of rope drag--unclipping the second to last bolt below the roof (after clipping the last bolt below the roof, of course) is advised. Long slings in other spots may help as well, although I didn't use them.
