mysterious no name climb near deckers

I am really wanting to know the rating for this climb I just did near deckers. On the climb for South Murphy Dome they mention this area in the directions as half dome. It was bolted but very dirty from under use. To get there follow the directions for south murphy dome but once headed up off the road head back north (parallel to the road) which this dome is right next to or above the road. We noted maybe 4-5 bolted routes. The area is visible from the parking lot they instruct you to park in for south murphy dome. From the parking lot you can see a distinct crack through the middle of the rocks. The climb we did was the furthest bolted climb left on the south/east side of the dome. It was cramped up against a steep hill. It had 6 to bolts? to a 2 bolt wrap ring anchor. Help if you know anything.
