I'll answer my own question, but roports are the western descent is possible, but a 70m just reaches the 2 bolted belay. Stay in the gully to the right while facing the wall down to gear, or slings where another rap gets you to the bottom of the upper slabs.
Better descent is on the opposite side of the ridge from what is shown. As you walk down the ridge south from the summit, you can see two sets of anchors. The ones shown on the right, better ones on the left (looking down the ridge). From the left set of anchors, a two rope rap leaves you at the saddle (there is an intermediate anchor of fixed wires that makes this descent possible with a single rope). From the saddle, scramble east for a short distance where another short rap gets you to the walk off back base of the route.
