Miguel Carmona and I climbed the Third Pillar Headwall in a 20 hour push in September 1990. The two crux pitches on the almost vertical headwall of the Pillar were wonderful mixed free and aid (5.10+ and A2+ new wave rating) climbing. Great route that suffers from being about 100 feet away from one of the best rock climbs in California.
Mixed up our own variation with some of the same pitches, and some of our own a while back. Need to go back and put this together.
