Climb the thin crack on the left wall of the chimney that trends deeper into the chimney (watch out for a pile of guano in a jug). When the chimney narrows to an offwidth/squeeze, traverse back out and grunt up through the squeeze chimney (crux, protects with #6 Camalot). Continue grunting up the squeeze to easier terrain, climb over a huge chockstone and continue up a short finger crack to a 2 bolt anchor on the right. Shares anchors with Know Your Enemy.
Location
Far west end of Mighty Mouse Wall. From the start to Elysium, scramble left and up to the first chimney through some scrub oak. See Beta photo on main page.
Protection
BD singles #0-3 C3, #0.4-#6 C4, set of stoppers and slings. 2 bolt anchor at top, rap 75' to the south.
I agree it would be more difficult for a larger person. You would have to traverse further out of the squeeze where the chimney flares and the moves become marginal but not impossible, making the crux a little stiffer. Watch you rope drag over the #6 Camalot at the crux, it could walk back into the squeeze and tip out.
