Innocence is located on the east face of the Red Slab Buttress between Congestion Chimney and Puffs Plus. Climb up the face just right of the corner using nice face features. After a few moves head right onto a less-steep slab of rock.
Three years later ... someone was just reminding me that my belay at the top was a sling wrapped around a swaying tree limb.
What I remember at this point is 5.7ish moves, and having to work for one of the pieces in the initial steep section. The crack is what attracted me to that piece of rock. I doubt I led a 5.4 there. It's possible I just missed something, or its possible I was imposing route rules on myself. There are tons of contrived routes in Swartling & Mayer.
