||About 1 miles before the Cal Domes approaches, the road crosses a creek flowing into the river. 100 yards before this is a dirt road that heads up and north. Follow this road until you can't drive further. Now, follow a trail that crosses the aqueduct, and then ascends stairs (down and left is the Stairs cliff), follow around cliff (two nice routes), go up a steep dirt slope, and then down 71 stairs. Another 200 yards further (cross the aqueduct) is Sergeant Rock. There are also nice routes here.
