For what it's worth (think Zimbabwe dollars), here's my route for tomorrow. I estimate it at roughly a dozen miles. I have no intention of deviating from the route, but if I did it would be to bail out to the west back to the CR&HT. In the extremely unlikely event I had to hole up and wait for rescue, I would make every effort known to man to get to the aforementioned meat eating bushes in Smith Water (point "O") where there is at least some form of water. I carry a 406 MHz PLB, a whistle, a light, a Verizon cell phone, and a signal mirror.
I plan to do the majority of my searching around points "N" and "O". I probably won't travel in a straight line between the two points. I'm particularly interested in places that would be shielded from the morning sun. Bill's ping was detected early Sunday morning. Assuming he kept moving, he'd have been on the ridge that leads to Smith Water Canyon in the morning. It's possible that he crawled out of the sun... and never resumed crawling. This is part of why I thought glassing the area from the opposite ridge might be worth while (you'd be glassing in the opposite direction from the morning sun, looking directly at areas that would be sheltered from the sun in the morning hours). If possible, I'll hit points "K" and "M" which would be logical points from which to survey one's options on the descent. I consider these low probability, but since I'm there, why not?
Say a prayer for me... and for Bill's family and friends. Speaking from (very) personal experience, closure is a good thing.
