From the main zone drive south, go right at the fork on warm point road and drive past warm point. Make a left on Blind Canyon road and drive for quite a long ways, past Snake Canyon road, to Garrison-Black Rock Road. Hang a right and drive towards the obvious Crystal Peak in the distance. Pass Crystal Peak and proceed down the other side of the mountain. At the bottom of the hill about 3 miles past the peak is a pasture, on the far side of this a smaller road takes off to the left. Take this road heading south. Drive until you see some big cattle watering troughs on the right. Past the second of these, find a faint jeep trail that leads east. Follow this til it peters out, then hike towards the quartzite cliffs over a big sand dune, bearing uphill and to the right. At the base of the cliff you will find the Scorpion boulders, it is only a little bit further to the main area and the Sand Woman area.
