Halfway between the 170' rappel above the lunch ledge and the lunch ledge rappel itself: the shadows of the groove, above the chickenheads for S-direct, there is another bolted station.
This station landed us about 15 feet short of the lunch ledge rappel. Had to set up an interim anchor for easy down climbing to the rap.
Here is my crappy update to Lee Jensen's nice topo (Sorry I hijacked your topo Lee). We brought 2 ropes, and everything went pretty smooth. I think it took us about an hour to descend, and we were a party of 3.
