Up past some bushes and to the left of the boulder-choked gully where Platinum Stethoscope begins is a hand crack close to the right edge of the slab. This crack takes gear in the 1.5 - 2 inch range. Climb up the crack and the steepness eases off. Pass a small tree about three feet tall on the right. Then enter into a trough about four feet wide with a thin crack on the right side. This takes very small nuts or perhaps a microcam, but the gear is not great. Climb up this 15 ft. trough and go out onto the 5.0-5.2 slab. Pro is harder to find here, but you will more than likely be comfortable running it out the rest of the pitch. Meet up with the walkoff for the first two pitches of the routes to your right.
We simulclimbed this as one pitch, which is easy to do. The climbing is never sustained and one can easily downclimb the entire thing. Finding your way on the upper slab is easy, as any direction will feel good given the gradually declining steepness. By the time you reach the walkoff, it flattens out.
Approximately ten feet left of Platinum Stethescope. Locate the gully where Platinum begins and then scramble up and left through the trees to find the hand crack.
Standard trad rack for Lumpy, including cams in the 1.5-2 inch range and some microcams/nuts.
