3-Star 

You can get too and from this route via the top rock trail between hanger 18 and area 51 easier than from the caves trail. After you re-enter the woods from the brush-field that was clear-cut a few years ago heading towards area 51, walk a few hundred feet and look for white splotches painted on the trees to your right. If you follow these (there is no trail, just bushwacking) and trend a bit left off of them, after about 200 yards, you'll end up at the top of 3 star. It's tough if you've never been there because the climb faces away from you in kind of a pit, you can't see it coming, it is not a large outcrop visable from this approach. You have to downscramble to get to it's base. If you're too far right, you'll end up on looking at a messy down scramble, but if you turn and look left, you can see the face of 3 star about 100 feet away.
