Your objective is to climb the splitter cracks on the right side of the dome's south face, and this route follows the easiest path (although not the most direct line) to the base of the cracks.  Starting from the left (west) side of the Upper Dome's south face, traverse right, walking atop a large flake.  Keep traversing right past the end of the flake, proceeding along an inobvious but easy line, to the base of the three cracks, which then lead to the top.   See the photo topo in the excellent online guide.

Last Chance

This small dome forms the summit of the Ribcage crags.  If you've come this far, and climbed Out of Darkness and Winter Solstice slabs, you might as well finish off your multipitch cactus-climbing adventure by ascending the south face of Upper Dome as well.  The excellent online guide lists three short routes up this rock.
