The dirty rail is a unique roof climb located up the hill in the wash in the Calico Basin area. It's definitely a problem worth checking out.
Park at Kraft and hike west until you see the old foundation. There's a trail that goes south and into the wash up the hill. It can take 30-45+ minutes to get to the boulder. It's not very far in terms of distance, but it's uphill and the terrain can be a bit difficult to maneuver through with a crash pad.
