Right most problem on creek boulder. Sit start with right hand on one of the 2 side pulls that you use to start pop rocks. Climb right and top out.
Just above the amphitheater in the middle of the wash. It is before the valley that opens up but after a narrow section of wash with gray, smooth, water washed walls. The best entrance I have found is scrambling up the left side of the amphitheater like you are going to the top of the boulder pile in the middle of the valley. Then drop back down into the wash from the top of the hill.
