For some reason he went by himself a different way than the boys and the other leaders. Never made it out at the other exit. Other hikers reported seeing him, but apparently he didn't try to contact them for help. I wonder if he maybe ran out of water and got disoriented. It's kind of weird.
If S&R isn't available for some reason (we're waiting on confirmation now), I'll be heading out with two other ward members to go search. Probably start at first light tomorrow morning.
